New formulations of thyroxine for treatment of hypothyroidism

New formulations of thyroxine available in Australia

A new brand of thyroxine is now available in Australia. The Therapeutic Goods Administration has approved a new generic and new strength brand of thyroxine under product names of Eltroxin, Aspen thyroxine and Thyroxine Aspen in 2014, sponsored by Aspen Pharma Pty Ltd. This brand of throxine has been widely used in Europe and other countries. Previously we only had two brands of thyroxine in Australia, Oroxine and Eutroxsig.

Eltroxin tablets come in a plastic bottle in new strengths of thyroxine sodium – 25, 50, 75, 88, 100, 112, 125, 137, 150 or 200mcg tablets. They also do not need refrigeration (not above 25 degrees C) which may be useful when traveling for example or for finer adjustment of hormones. Eltroxin might be an easier option for some people who are taking two doses of Eutroxsig at different days of a week (like myself). When changing from on brand of thyroxine to another, it is important to note that dosing may not be interchangeable due to different fillers present in tablets as they may change the bio-availability of thyroxine in individuals. It is important to monitor hormonal levels when changing from Eutroxsig/Oroxine to Eltroxin, which may be slightly less bio-available when compared to Oroxine (you might need to take a slightly higher dose). I have not tried Eltroxin but would be very interested in any comments from people who take it or switched from one brand to another.

New liquid thyroxine (not available in Australia just yet)

SERB company in France has developed a liquid formulation of thyroxine, levothyroxine in drops. One drop contains 5 mcg of thyroxine. This formulation might be beneficial for young children and older people who have problems swallowing tablets.

FDA in USA has also approved a liquid formulation-Tirosint-SOL (levothyroxine sodium oral solution; IBSA). It is supplied in unit gel capsule containing following strengths (mcg/mL): 13, 25, 50, 75, 88, 100, 112, 125, 137, 150, 175, 200 (colour labelled). It contains only levothyroxine, gelatin, glycerin, and water.  It has been developed by Italian Swiss Company IBSA and it has been available in Italy since 2012.

Hypothyroidism and a low resistance to colds and flu- natural remedies

Hypothyroidism and a low resistance to colds and flu- natural remedies

This blog will only discuss scientific research on natural remedies which may help to fight off a respiratory infection during the flu season. The flu and the common cold are caused by different viruses with flu being generally more severe than a cold and harder to overcome.

My experience with sub-optimal thyroid hormonal replacement made me aware that my risk of getting common colds and flu increases when I was hypothyroid. In fact, I used to have a constant cold during winter which lasted for months when I was hypothyroid. The flu was also more severe and hard to overcome. Number one resistance from colds and flu in thyroid patients is to have optimal levels of thyroid hormones (TSH, T4 and T3) in my opinion. This is important as sub-optimal hormonal replacement affects all body systems negatively, including the immune and digestive systems.

Nutritional deficiencies are common with hypothyroidism which affect cause a lowered resistance to viruses. Common deficiency with thyroid autoimmunity are iron, B vitamins and vitamin C, D and vitamin A with hypothyroidism. It is also important to have adequate vitamin D levels. Vitamin D is a steroid hormone that balances the immune system obtained from the sun, therefore a reasonable sun exposure is beneficial. I personally supplement with vitamin D during winter months to have optimal levels. It is common do have low levels of vitamin D with thyroid autoimmunity.

The winter season is approaching in the southern hemisphere and so too here in Australia. However I feel that the warmer months are the time to boost the immune system. Vitamin D from the sun, fresh seasonal fruits and vegetables, swimming in the ocean, outdoor walks, relaxing summer holiday, all these enjoyable things leave healthy deposits in our body so that we are stronger during the colder months and are more able to fight off colds and flu virus faster. We need strong adrenals to overcome winter illnesses. Certainly when we are stressed, our immune system is not strong enough to be effective in fighting viruses. When we are hypothyroid we are severely weakened, we have lowered immunity and other hormonal imbalances. Therefore resistance to flu viruses involves a whole body approach.

Viruses are tiny (much smaller than bacteria) and they only replicate inside of a host cell. They can attach and then invade a human cell. Viruses are like tiny protein robots which carry genetic material that instructs the host cell to make more viruses, destroying the host cell in the process. Respiratory viruses like the Influenza virus are spread by coughing and sneezing. They can be breathed in but viruses can survive on surfaces for up to 24 hours so touching a contaminated surface and then touching your nose, mouth or face can cause an infection. Really, our immune system is our best defense against a viral infection.

Viruses can be ‘killed’ by heat (75-100 degrees C) and by some cleaners, detergents, soaps or hand gels. Hand gels and sanitizes are mainly antibacterial but also work for viruses given sufficient time of contact so it is good idea to rub the gel until hands feel dry.

Viruses are not really killed as they are not alive to start with but their protein and genetic material becomes damaged so they become are unable to invade a host cell. Antibiotics work only on bacteria and do not work on viruses and there are limited antiviral medications. Antibiotics are given for secondary bacterial infections as  mucous membranes damaged by viruses are easily invaded by opportunistic bacteria.

Here I would like talk about some of the current research into natural remedies for overcoming colds/flu much easier.

It is beneficial to have lots of colorful vegetables in a diet, mainly because they can alkalize body cells which then become are more resistant to invasion by viruses. Anthocyanins (a type of flavonoid) is a group of compounds with amazing antioxidant effects. A scientific study (3) has discovered that certain gut bacteria called Clostridium orbiscindens, degrades flavonoids to produce a metabolite called desaminotyrosine which boosts the immune system and prevents influenza-related lung damage in the mice.

Colostrum may also be an effective supplement for flu prevention. Italian researches have stated in their study (20) on Colostrum: “Colostrum, both in healthy subjects and high-risk cardiovascular patients, is at least 3 times more effective than vaccination to prevent flu and is very cost-effective.”

We all know benefits of garlic for combating colds. A study (21) of one hundred forty-six volunteers investigated allicin containing garlic supplement for flue prevention. It has  concluded that: “An allicin-containing supplement can prevent attack by the common cold virus.”

Raw apple cider vinegar is believed to be great for the immune system as it improves the balance of gut bacteria. It also stimulates absorption of nutrients from food.

A prominent physician in 1925 has made an observation that Bicarbonate of Soda had some protective effects on fighting influenza while working for U. S. Public Health Service during 1918- 1919 flu epidemic. Some people believe that small amount of baking soda in water can help to resolve colds, taken on onset by alkalizing the body. I have not tried this myself and have not found any current research in support of this remedy but for those interested, there are a number of interesting websites which discuss it, I include some (15, 16 and 17).

A great alkalizing fruits are lemons, even though they taste acidic, they change in the body to alkalizing substances.

People with autoimmunity need more antioxidants in their diet. One amazing vegetable with incredible amount of anthocyanins is red cabbage. It is a worthwhile vegetable to include in your diet in winter. Fruits such as blueberries also contain lots of anthocyanins and if you can have these in winter months, it might be beneficial. Fermented foods and probiotics might also help.

Adrenal support might be important especially if you are stressed or overworked. Good sleep is important for the immune system. Adrenal glands need lots of vitamin C and B to function well. Adequate levels of zinc and magnesium are also important. Zinc tablets and lozenges are beneficial for sore throats. Epsom salt baths or rubbing with magnesium gels may be beneficial to increase magnesium levels as it gets absorbed through skin. Very warm Epsom salt feet soak is wonderful when you have a chill. It is beneficial to keep your feet warm. Last winter I found that if I had a teaspoon of vitamin C powder 3 times a day in some water, it helped with my cold and muscular aches.

Everybody has their own cold remedies passed through generations. The goal is to get over a virus as soon as possible without getting a secondary infection which would require antibiotics. Having an appropriate rest is important.

A study has found that some essential oils attenuate influenza virus infections. These oils are: wild orange peel, clove, cinnamon, eucalyptus, thyme and rosemary. A scientific study (5) has shown that several oil blends such as On Guard™ have antiviral activities.

Few drops of these oils may be added to some vodka in a small spray bottle and used to spray in the house. The oils may be used in diffuses or vaporizers.

Good old chicken soup or bone broths provide many glutathione building nutrients. Glutathione molecule is important for the immune system to function well. Most of us know the benefits of garlic, black elderberry, cinnamon, ginger, raw honey in fighting of colds. A hot toast with butter, honey and sprinkled with cinnamon is soothing as well as garlic and butter toast. My friends swears by a smoothie containing lemon juice, ginger, garlic and parsley. Some people like the benefits of Echinacea extract. It was found to stop the virus binding to cells in an in vitro study (6). However some people with ragweed or pollen allergy might be allergic to Echinacea as their molecules are similar. Ragweed or pollen allergy are quite common in people with thyroid autoimmunity. Lots of warm drinks with lemon, ginger and honey helps to soothe a sore throat. Green, black and liquorice teas have some antiviral activity. Polyphenols in black tea called theaflavins have antiviral activities (7). Coffee components (such as caffeic acid and natural flavonoids) have also been shown to have anti influenza virus activities. Resveratrol in grapes is also known for antiviral properties. Guava leaf tea was shown to have a stronger anti-virus activity than green tea in a study, probably due to the presence of flavonoids (8). Olive leaf extract has also shown to have anti influenza effects (11). Gurgling a sore throat with olive leaf tea may bring some relief. Hibiscus tea may help as it is rich in vitamin C.

A study (1) on mice has shown that extract from leaves of wild black currants (500 micrograms) given to mice through nose stopped the replication of the human influenza A virus in lungs by 85% when compared to other mice. The extract was also effective in cell cultures infected with influenza virus. The scientist believe that this extract may also be beneficial to humans. The leaves are rich in phenolic compounds in particular flavonoids and tannins which are believed to be responsible for the antiviral effects.

Cistus incanus tea may also be beneficial for influenza. A scientific study (2) has shown that Cistus inacus extract has anti influenza virus activity in cell cultures study blocking the virus entry into the cells.

Herbs known for its antiviral properties include rosemary, thyme, sage, fennel seeds and oregano. Marshmallow root and black elderberry extract (Sambucol) can soothe inflamed membranes. Inhalers with tea tree oil, rosemary, eucalyptus, lemon, thyme, oregano or lavender may be beneficial. The oils can be used in steam breathing, vaporizers, baths, compresses and for rubs in massage carrier oils.

Andrographis paniculata (King of bitters) study (18) has shown Kan Jang tablets containing this herb had a preventive effect against common colds during the winter period.  Astragalus root is also known for the anti-viral and immune boosting properties.

Let’s not forget about iodine, a potent killer of viruses. Iodine is used to make a thyroid hormones in the thyroid gland. Some people with hypothyroidism may be iodine deficient. Iodine should be used carefully by people with Grave’s disease as it may aggravate the symptoms in some cases.

Aerosol sprays with iodine can kill viruses, iodine gargling preparation from your local chemist may also be effective. Scientists, Burnet and Stone had experimented with iodine and influenza viruses on mice in Melbourne laboratories in 1945 and had found out that putting iodine on mice snouts prevented the mice from being infected with live influenza virus from 10 min exposure in high concentration virus mists.

I always make sure that I have my own herbal remedies for winter (recipe below) for winter coughs and colds. This tea is helpful for coughs, irritated throat and it makes sleeping easier.

 

Soothing tea for colds and coughs:

4tbl spoons dry marshmallow root

2tbl spoons thyme dried

2tbl spoons dried fennel seeds

2tbl spoons dried sage.

Gut and autoimmunity connection

Gut and autoimmunity connection

The health of digestive system is very important for people with autoimmunity problems. Our immune system is closely connected with our gut. The intestines can be compared to the roots of plants that absorb nutrients for them to grow. If the soil is poor and roots weak, the plant will be struggling to survive. Unhealthy gut has been connected to autoimmunity.

There are few factors which can benefit the health of our digestive system. These are: healthy diet, lots of vegetables (including some cruciferous ones like broccoli, cabbage, horseradish, wasabi), herbs, fiber, fermented food, limiting processed food, avoiding foods one is sensitive too (like gluten) and avoiding stress. Frequent use of antibiotics and some other medications (like steroids, NSAIDs- aspirin, ibuprofen and others ) can also affect the balance of bacteria in our gut and promote imbalances with a loss of beneficial bacteria. Antibiotics and some other medications can damage the lining of our intestines. Frequent infections may also have a negative effect. Hormonal balance is also very important for gut health. Imbalance of thyroid hormones for example may lower the stomach acid, digestive enzymes and bile and change the time food travels through the digestive system, ultimately causing an imbalance in gut bacteria, nutrient deficiencies and health issues.

The gut flora consists of over 500 species of bacteria (Firmicutes/Bacteroidetes most common), fungi and viruses. Beneficial bacteria help to digest food, absorb and make vitamins (B and K2), help to metabolize hormones and other chemicals (such as short-chain fatty acids used for energy by our body) that keep our body healthy and our immune system balanced. They help to remove toxic heavy metals (6, 7). Lactobacillus strains were found to be able to absorb and remove cadmium from culture mediums in a study (8). Cadmium toxicity has been implicated in thyroid autoimmunity.

We live in a symbiotic relationship with our gut microflora as it interacts with the cells of the intestines. The live microorganisms in our gut interact with our nervous system and our immune system as well, they can induce a production of certain immune-regulatory molecules which are also absorbed by our intestines. Balanced gut flora can help the immune system not to over-react. Most of our immune system is associated with our gut. Serotonin, happy molecule is produced predominantly by our gut. Beneficial microorganisms in our gut protect our body from bad, pathogenic organisms. If there is imbalance of gut flora and ‘bad’ inhabitants predominate over ‘beneficial’ inhabitants, the nervous system and the immune system of an individual will be affected. Some bacteria can influence our mood for the better, there is a saying healthy gut, happy person. It was found in animal study (2) that Lactobacillus rhamnosus (beneficial bacteria) in our gut can reduce anxiety by producing molecules which directly interact with our brain. Interestingly, Lactobacillus species can be depleted by overgrowth of Candida yeast. Even though having some Candida in the gut is normal, overgrowth can be a problem. Many people with autoimmunity may have imbalances in their gut microbiota (dysbiosis). An example of that is the lack of Lactobacillus or Bifidobacterium species in the gut. As mentioned before, lack of Lactobacillus can make a person more anxious. Different bacteria can have a specific effect on our body, for example Styreptococcus thermophiles may improve lactose intolerance.

Low stomach acid may play a havoc with the balance of bacteria in the digestive and immune system. Low stomach acid may be seen with thyroid hormonal imbalance and stress. Low stomach acid may allow harmful bacteria like H. pylori to survive (this bacteria may cause stomach ulcers). Low stomach acid is connected to a poor absorption of minerals and vitamins. This then causes loss of essential nutrients. Eating processed packaged food and food with preservatives (after all, preservatives do not allow bacteria to reproduce) will affect our gut flora. Diet high in sugar, high carbohydrate diet, predominantly wheat flour based products, fatty food, low in vegetables, fiber and low in fermented food and essential fatty acids can lead to an unhealthy gut. One more reason for imbalanced gut flora is stress. Stress activates the sympathetic nervous system in place of parasympathetic nervous system which is responsible for proper digestion of food. We cannot also forget about vitamin D which is absolutely vital for people with autoimmunity as it activates pathways to make antibacterial molecules which are designed to kill harmful bacteria in our gut and generally in the body. Vitamin D balances the immune system. Frequent use of some medications like the anti-inflammatory NSAIDs, steroids and antibiotics negatively alters the gut microbiota. High consumption of alcohol also alters the balance of bacteria in the gut.

Complete stool analysis test can determine the health of the digestive system, digestion and gut health. This test is generally requested by the integrative medical doctors so that the specific problems can be rectified. If you have bacterial gut imbalance (or parasites), you might be given specific probiotics or herbal remedies by your holistic doctor (such as those containing oregano, thyme, licorice, slippery elm, marshmallow root, olive leaf, garlic and other herbs) to correct the problem. If you have digestive problems, HCl-betaine (for a low stomach acid) or enzymes may be prescribed.

Gas, burping, bloating, heartburn, constipation, diarrhea, indigestion would be the obvious signs that there is something wrong with your digestion. However other signs can be allergies, itching and anxiety. Therefore, signs of gut microbiota imbalance can be difficult to recognize. Obviously if you suffer from thyroid problems, have imbalanced of deficient hormones, the digestive system will not work well. It is common problem with hypothyroidism. I had poor digestion and stomach ulcers as a direct consequence of being on sub-optimal thyroid hormonal treatment. Personally, I saw a great improvement in my gut health by adding NDT to my levothyroxine hormonal replacement, making sure my hormonal balance was the best I could achieve. My integrative medical doctor put me on a quality probiotic for a month.

Fermented food can help to balance gut bacteria (such as sauerkraut, other fermented vegetables). Eating organic, non- processed and non-preserved food can help. Soluble fiber was found to benefit intestines (found in oats, beans, lentils, peas, flax seeds, other seeds and some fruits and some vegetables). Supporting your adrenals, good sleep, rest and relaxation can help with stress and limiting frequent infections requiring antibiotics. Some people find colostrum beneficial for balancing their gut flora. Apple cider vinegar also helps to re-balance the gut. Hormonal balance is also very important. The health of the gut can be achieved back through a healthy diet, fermented foods, probiotics, herbal remedies, improving digestion with specific supplements (glutamine), avoiding food one is sensitive to, balancing hormones and limiting stress. Glutamine is great for a leaky gut but some people should avoid it, especially if they get more nervous after taking glutamine and in specific conditions) so consult your doctor regarding glutamine. I personally took glutamine supplement for a month (1 tsp) per day to improve my gut. The positive steps you will take in the direction of your gut health, can greatly benefit your overall health and help with autoimmunity problems.

Naltrexone – a promising medication for autoimmune disorders

 

Naltrexone – a promising medication for autoimmune disorders

Naltrexone is a medicine used in high doses to treat people with substance addiction problems. Naltrexone binds to opiate receptors.

When a person receives low doses of Naltrexone, it works only for a short time but manages to send signals to the body to increase the production of endorphins which assist in balancing of the immune system. Naltrexone is believed to have little side effects on the body in low doses taken at bedtime and it may help with metabolic processes. There are some positive reports from people with thyroid autoimmunity on internet forums. Many report a reduction in thyroid antibodies.

There has been some small pilot studies on use of Naltrexone for other autoimmune disorders (doses around 1.5 to 4.5mg/daily), such as Crohn’s disease, MS and fibromyalgia with positive outcomes. There are also reports of positive benefits in other autoimmune disorders and illnesses by pioneering physicians, such as Dr. Bihari.  However there are no scientific studies on Naltrexone and Graves’ disease or Hashimoto’s thyroiditis at the moment. Even though it has not been approved for treatment of Graves’ disease, some doctors prescribe it.

Naltrexone can increase the levels of endorphins in the brain. The levels of endorphins are lowered in Graves’ disease, also due to chemical imbalances in the brain and lowered levels of GABA, a calming chemical.  

So, why endorphins are so important? Endorphins are ‘feel good’ chemicals produced by the body like natural opiates, similar to morphine. They are a reward system for our body cells, which enhance our life experience. Endorphins are produced in the brain when we experience happiness, love and relaxation. They are reduced on exposure to chronic stress and pain, with levels varied among individuals. The levels of these ‘happy molecules’ may be reduced in people with autoimmunity. We can see that when describing what endorphins do in the body. They strengthen and balance the immune system, reduce blood pressure, heart rate, dilate blood vessels, slow down breathing, reduce stress, lower pain, slow down neuron firing, improve digestion, excretions of harmful toxins and give feelings of pleasure, love and reward.

To enhance levels of endorphins in the brain, smelling scents and oils, such as lavender, chamomile, rosemary, mint, vanilla and grapefruit may help. Rhodiola rosea herb may also help to increase endorphins. Nutritional yeast (or brewer’s yeast) is high in inositol, which may help to enhance endorphins. Flaxseed oil and fish oil enhance the release of endorphins. Cacao and chocolate stimulate the secretion of endorphins. Craving for chocolate and fatty foods might indicate low level of endorphins in a person. Other pleasurable activities, such as listening to slow rhythmic music, looking at beautiful pictures, smiling, loving, exercise, massage and laughter may all increase endorphins levels. Living peaceful life with positive attitude and expression of one’s feelings would enhance endorphins. Being in a secure, loving and stable relationship is also beneficial. Even acupuncture, reasonable sun exposure and spending time in nature increase endorphins levels. Meditation is also beneficial as alpha rhythms (electrical patterns or waves in brain), which increase during meditation, tend to stimulate the release of endorphins. Lack of vitamins C and B and other minerals reduces endorphins.

Thyroid hormonal imbalance and blood sugar problems

Thyroid Hormone Imbalances and blood sugar problems

Thyroid hormones imbalances, both hyper and hypothyroidism can cause poor blood sugar control, increase the risk of insulin resistance and the risk of developing type 2 diabetes due to effects of thyroid hormones on the production, demand and performance of insulin in the body and common genetic factors. There is plenty of scientific evidence supporting the contribution of thyroid hormonal imbalances to Type 2 Diabetes Mellitus. All hormonal system are intertwined. Autoimmune thyroid conditions also increase the risk of Type 1 Diabetes Mellitus ( autoimmune illness) and vice versa.

Blood sugar needs to be kept at between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). It is regulated by few factors: glucose storage and release from glycogen by the liver, intestinal absorption, glucose uptake in muscles and fat cells and the production of insulin by pancreas. Insulin is a hormone made in pancreas which takes the sugar out of blood when it gets too high.

Thyroid hormone imbalances change expression of certain genes and production of proteins which can affect insulin sensitivity of cells. They also cause changes in plasma fatty acids which also modulate insulin sensitivity.

Insulin resistance happens when the insulin receptors in body cells do not respond properly to insulin and so the sugar from blood cannot be taken inside of cells to produce energy. Insulin resistance can progress and lead to Type 2 Diabetes Mellitus, a conditions where pancreas can no longer produce enough insulin to overcome insulin resistance.

Thyroid hormone is the hormone that starts the energy production inside of the cells and insulin helps to supply the cells with fuel-glucose. The hormonal systems work together so it is clear that imbalance of one will imbalance the other.

Hyperthyroidism

The increase in thyroid hormones signals the body to rapidly increase energy production and stimulates liver through the sympathetic nervous system. That is the main reason for glucose intolerance. The needs for glucose increase to keep up with an increased metabolic rate. Growth hormone somatotropin is released accelerating the production of liver glycogen to glucose. There is also a rapid glucose absorption from the intestine. In Graves’ disease, more proinsulin is secreted from the pancreas. It is however not properly converted to insulin. Insulin is also more rapidly degraded in kidneys. Hyperthyroidism is associated with insulin resistance of liver cells. The liver cells overproduce glucose and are ‘deaf’ to insulin signals. However, the skeletal muscle cells have an increased glucose absorption. The production of energy from glucose is changed towards glycolysis and lactate formation in muscles. It has been shown in Japanese studies that people with Graves’ disease are twice as much of a risk of developing non insulin-dependent diabetes (type II) diabetes when compared to a healthy population (1).

A medication, called thiazolidinedine, used sometimes to increase insulin sensitivity should not be given to people with type 2 diabetes, thyroid autoimmunity and ophthalmopathy as it may worsen the eye condition (7). Also when people with thyrotoxicosis (excessive thyroid hormones) and diabetes are given too much insulin, they at risk of diabetic ketoacidosis, which increases the risk of a cardiac arrest, therefore these two conditions of hyperthyroidism and diabetes need to be controlled properly.

Unfortunately, there is also an increased chance of developing Type 1 Diabetes, which is Insulin Dependent Diabetes Mellitus, an autoimmune condition. People with thyroid dysfunction (not related to autoimmunity) do not have an increased chance of developing Type 1 Diabetes Mellitus which is an autoimmune illness. Type 1 Diabetes Mellitus can co-occur with Graves’ disease as both are autoimmune conditions and they have common genetic components. This is often seen in younger people with Graves’ disease. The chance of having another autoimmune illness with Graves’ disease is about 9-10% and slightly higher for Hashimoto’s thyroiditis (19).

Hypothyroidism

T3 is an extremely potent elixir of life. Hypothyroidism and insulin resistance go together. Lack of T3 (even sub-clinical) may lead to blood sugar problems, insulin resistance and type 2 diabetes. The risk of developing type 2 diabetic is higher in hypothyroidism than hyperthyroidism. Low T3 causes liver and pancreatic function to be poor, lowers the secretion of insulin and stresses those organs. Low T3 also causes impaired glucose metabolism in peripheral tissues. The peripheral muscles become less responsive to insulin. The transport of glucose inside of cells is impaired due to lowered expression of transport genes due to hypothyroidism. Also there is reduced disposal of glucose. Under methylation issues has been postulated as a possible mechanisms, which increase insulin resistance. Another one is the dysregulation of metabolism of leptin, hormone which regulates hunger. Hypothyroid people store less glucose in the liver as glycogen and are more prone to low blood sugar. As a consequence, both adrenaline and cortisol start rising at night.  Adrenaline can peak around 2am and a person can wake up with heart palpitations. Cortisol hormone may be high in early morning, raising fasting blood sugar. I certainly had that happen to me when I was hypothyroid as mentioned in my previous post. I used to get up and have a snack in the middle of the night, which always stopped the heart palpitations.

Thyroid is a major player in the part of brain called hippocampus which is very vulnerable brain region in general as it modulates glucose metabolism and insulin signalling. Damage to hippocampus has been connected to hypothyroidism, memory problems, special navigation problems, dementia and Alzheimer’s disease. It may also be connected to the development of type 2 diabetes.

Metformin is sometimes given to people with insulin resistance to improve their insulin sensitivity, however optimal thyroid hormonal replacement may also be effective in increasing insulin sensitivity in some cases. Metformin may deplete vitamin B12 so it is important to watch your levels. It was noted that the levels of TSH decrease with metformin in people on levothyroxine hormonal treatment which indicates that there is an improvement in hypothyroid state (10, 11) without a change in FT4 levels, thyroid hormones seem to work better with improved insulin sensitivity. This is not surprising as too much insulin is antagonistic to thyroid hormones and blocks thyroid hormonal receptors.

In my personal case, I had blood sugar issues when I was on levothyroxine only hormonal replacement and also when I suffered from thyrotoxicosis. My glucose tolerance test was impaired.

Natural desiccated thyroid and levothyroxine combination had normalised my blood sugar. Natural bio-identical progesterone hormone which I was taking while on levothyroxine only hormonal replacement also helped in improving my blood sugar. Progesterone enhanced my T4 into T3 conversion all by itself and improved my hypothyroid symptoms.

Obviously type 1 diabetics need insulin hormone for survival as the pancreatic beta cells producing insulin are destroyed by an autoimmune reaction.

Ways which may improve insulin sensitivity and lower blood sugar:

Vitamin D helps thyroid autoimmunity and insulin resistance and increases insulin secretion from pancreas (16).

Optimal thyroid hormonal levels, proper control of hyperthyroidism and hypothyroidism is important.

Optimal hormonal replacement for hypothyroidism, consider NDT or levothyroxine/NDT combination to improve blood sugar control

Balancing other hormones

Other:

Vitamin B1 especially (Benfotiamine, fat soluble form of B1 might be beneficial)

Chromium mineral, vanadium, and B vitamins (Brewer’s yeast can provide these)

Magnesium

Vitamin C, clinical study shows that vitamin C can lower blood sugar (9)

Changes to nutrition (sugar limiting, healthy vegetable rich diet, more fibre, less saturated fat and more essential fatty acids (fish oil, flaxseed, and olive oil), not combining protein and sugar in a meal)

Essential fatty acids, coenzyme Q10, alpha lipoic acid, zinc

Exercise (short bursts of intense exercise were shown to reduce insulin resistance)

Limiting stress as cortisol produced during stress, increases blood sugar

Apple cider vinegar

Herbs which may help:

Gymnema sylvestre (good formula is GlucoBalance by Mediherb which also contains vitamins and minerals), small human study (18) showed positive blood sugar lowering effects.

Others: Bitter melon (also available in capsules), garlic, onion, prickly pear, soursop, chaste berry, Rhodiola rosea, guava leaves, fenugreek used in cooking and cinnamon

Thyroid problems and blood pressure connection

Thyroid problems and blood pressure connection

Blood pressure can be affected by many factors. Thyroid hormone imbalances affect blood pressure greatly. In my previous post, I had talked about body temperature being indicative of thyroid dysfunction. Blood pressure is also a strong indicator of thyroid function for people with thyroid hormonal imbalances. It is important to observe body signals as they are number one indicators that something is not right with thyroid hormones for people with thyroid issues.

I remember one day driving to my doctor for a check- up visit in heavy traffic while munching on chocolate coated coffee beans. I was almost late and when I saw my doctor, I was a bit flustered. I had a busy, stressful day. During a consultation with my doctor, she measured my blood pressure and it was through the roof. I do not know about you but I always get a bit nervous when my doctor is about to measure my blood pressure despite trying to stay calm and breathing deeply. Just feeling stressed, uncomfortable can raise blood pressure by itself. Blood pressure often fluctuates throughout the day. However it is not the temporary spikes of blood pressure we have to worry about but the sustained, chronic high blood pressure. Some people are not aware of their raised blood pressure. Blood pressure problems may be silent. For me, headaches, general tension, pins and needles in my arms and whooshing sound in my ears in the evening points to a possible blood pressure problem and possible hormonal imbalance. During my consultation that day, I had found out that my TSH value was 0.22, too low for me. I operate best at value of 1.7 so the dose of my hormonal replacement was slightly reduced and blood pressure came down. I also stopped drinking coffee and went to have decaffeinated variety and no more chocolate coated coffee beans!

I will explain how thyroid hormones affect blood pressure. When your doctor measures your blood pressure with a blood pressure monitor (sphygmomanometer), she or he inflates a cuff on your arm to collapse and then release the brachial artery under the cuff. A doctor usually uses a manual sphygmomanometer and listens to your brachial artery through a stethoscope. However there are digital blood pressure monitors available as well. When the pressure is released slowly from the cuff, the doctor listens to a first whooshing sound in your artery. This sound represents your systolic reading, it is when the blood starts flowing again in the artery, forced through by a heartbeat. Then as the cuff falls farther, the sound stops and the reading of diastolic blood pressure is taken at that moment. That reading represents the blood pressure in your artery between the heart beats, at the resting phase of the cardiac cycle. Therefore, blood pressure represents the force of blood against the arterial wall. The systolic pressure shows the power of the heart contraction and the force of blood being pumped in the artery. The second diastolic pressure represents the dilation and flexibility of the arteries.

Normal blood pressure is around 120 (systolic) and 80 (diastolic), 120/80.

High blood pressure is 140/90 or above.

The operating centre for blood pressure is present in the brain stem where signals from the body are processed. Blood pressure system is regulated by renin- angiotensin- aldosterone system and by sympathetic nerves and hormones adrenaline and noradrenaline.

While, there are many factors which can influence blood pressure, I will concentrate on thyroid dysfunction specifically in this post. Both the sympathetic and hormonal systems are deregulated in thyroid dysfunction. It has been suggested in scientific literature that there is a disconnection in the renin-angiotensin-aldosterone system in both hyperthyroidism and hypothyroidism as the functioning of kidneys is affected. Thyroid and renal function are interrelated.

 

Hyperthyroidism

People with Graves; disease have an increased rate and depth of respiration as well as higher blood pressure and a rapid heartbeat. There may be over 100 heart beats per minute. The systolic blood pressure is usually considerably higher than 120 and more raised than diastolic. Normal blood pressure is around 120 (systolic) and 80 (diastolic). In hyperthyroidism the reading for blood pressure is generally (≥140/<90 mm Hg). It is called systolic hypertension. It is also called secondary hypertension as thyroid hormones are the underlying cause of the high blood pressure. The pulse pressure is the difference between the systolic and diastolic pressure. The normal resting pulse pressure is therefore around 30-40 mmHg. People with GD have widen resting pulse pressure.

Too much thyroid hormones in blood increases metabolic rate. The heart and cardiovascular need to adjust. The excess of thyroid hormones increases the use of oxygen in the body. The sympathetic nervous system (SNS) is dominant in Graves’ disease, activated by excessive thyroid hormones. It is a system which is normally responsible for a ‘fight of flight’ body response to a dangerous and stressful situation and it releases catecholamines- epinephrine and norepinephrine from adrenal glands to accelerate the heart rate and increase blood pressure. The effects of hyperthyroidism include increased cardiac output, contractility, tachycardia, widened pulse pressure and dilation of peripheral blood vessels. Heart often goes into a ‘marathon run’. Heart related problems, such as palpitations (strong and fast beating of the heart) is a common symptom of Graves’ disease. This can also cause irregular heartbeat sometimes. Atrial fibrillation (type of a heart arrhythmia) can be seen.

Thyroid hormones increase other hormones such as aldosterone (from adrenals) and renin (from kidneys) secretion. This also increases blood volume and blood pressure by causing water to be reabsorbed along with sodium while more potassium is excreted in urine. Thyroid hormones and kidneys stimulate the development of red blood cells which also increases blood volume. Kidneys increase in mass with hyperthyroidism. Long term hypertension may lead to heart disease as it strains the heart. 

Hypothyroidism

Generally, hypothyroidism can in time significantly increase diastolic pressure, raising it above 90 mm Hg. It is often called hypothyroid hypertension. This is due to the fact that over time, continuous hypothyroidism causes changes to blood vessels, they become ‘stiff’ and constricted. The systolic blood pressure reading may also become elevated. However, there is a narrow pulse pressure.

Hypothyroidism is very stressful for the body. The body has to increase blood pressure to fight the slow metabolic rate and consequences of negative effects of low thyroid levels. It tries to do it with other hormones and molecules. The sympathetic and adrenal system is activated. The levels of adrenal norepinephrine were found to be elevated in hypothyroidism. Adrenal aldosterone hormone imbalance is connected to hypothyroidism and its increased levels may result in a constriction of blood vessels and elevated diastolic (bottom number) blood pressure. Cortisol hormone levels spike at times, especially in the morning in order to raise blood pressure and to increase the heart rate. Aldosterone hormone can spike about 2am. I had found myself  awake at 2am with heart palpitation when I was on a levothyroxine hormonal replacement only. I discovered that if I had something to eat in the middle of the night, my palpitations would stop. Aldosterone hormone increases blood pressure to deliver more glucose to body tissues when levels get too low due to hypothyroidism. At the same time the kidneys function is slower and they can get smaller in size. It was found that plasma renin (produced in kidneys) and angiotensin levels were lowered with hypothyroidism. Water clearance is reduced. Hypothyroidism is a low-renin hypertensive state, which means that levels of sodium in body decrease causing fluid retention. Low thyroid hormonal levels result in the inflammation and plasticity loss of blood vessels. Arterial stiffness is an important determinant of arteriosclerosis, which increases the risk for heart attack and strokes. Thyroid hormones promote the synthesis and action of vasodilators which acts directly on muscles in our arteries. However with low levels, the vessels become less flexible. The synthesis of nitric oxide (a powerful chemical, which dilates blood vessels) from L-arginine is stimulated by T3. Imagine your heart trying to pump blood through blood vessels in the body, which cannot effectively dilate and a resulting stress and damage to the cardiovascular system.

My own experience

The levothyroxine hormonal replacement after my thyroid surgery has raised my T4 levels high over time (in the top of the T4 reference range) while my T3 hormonal levels were low borderline. I suffered from T4 thyrotoxicosis and T3 deficiency. I had developed severe high blood pressure, felt stressed, had needle and pins in my arms and suffered from severe migraines. I went to see a doctor who prescribed a beta blocker -propranolol for my blood pressure problems. I started taking the medication but after few weeks I developed severe muscle spasms, horrible pains in my jaw and terrible muscular pain coupled with some degree of depression. I went to a doctor again and I got prescribed strong antibiotics because he believed my inability to open my mouth and the pain in my jaw and ears indicated some severe throat infection. I came home, while drinking water through a straw and shaking, I had a light bulb moment and realized that propranolol stopped the conversion of T4 (levothyroxine) to T3 (active hormone) in my body. The blood pressure medication had severely depleted my T3 levels which were low to start with. I did not have throat infection or some other terrible illness, I had a severe T3 deficiency. The balance between T4 and T3 is vital. It seemed that in my case, the high T4/low T3 levels caused my high blood pressure. Both, my systolic and diastolic readings were increased but my diastolic blood pressure was significantly raised.

My experience has lead me on a journey of discovery. I had learned that balancing my hormones is important for lowering my blood pressure. I added Natural Desiccated Thyroid (NDT) to my levothyroxine treatment, which ended my blood pressure problems at the time.

Since then, I had invested in blood pressure monitor and check my blood pressure occasionally. It is important to make sure the thyroid hormonal replacement is optimal as any imbalance will eventually show in blood pressure changes. Also, levothyroxine only treatment created a state of oestrogen dominance in my body, which farther decreased T4 into T3 conversion. Natural progesterone cream also helped to get my blood pressure to completely normal levels. More on that in later posts.
