What is hyperthyroidism?

Hyperthyroidism is when the thyroid gland produces too much of the thyroid hormones thyroxine (T4) and triiodothyronine (T3).

An overactive thyroid can cause a wide range of symptoms, including:

• nervousness, anxiety and irritability
• mood swings
• difficulty sleeping
• persistent tiredness and weakness
• sensitivity to heat
• swelling in your neck from an enlarged thyroid gland (goitre)
• an irregular and/or unusually fast heart rate (palpitations)
• twitching or trembling
• unexplained weight loss

What causes hyperthyroidism?

The most common cause of hyperthyroidism is the autoimmune condition Graves Disease, which is much more common in women than in men and typically seems to be activated by a stressful event or an emotional shock. There is also a genetic component, as well as a susceptibility to gluten sensitivity or coeliac disease.

Iodine supplementation when levels are already adequate is also a predisposing factor for someone to develop hyperthyroidism/Graves disease.

Most common symptoms are nervousness, irritability, sweating, palpitations, insomnia, loose and frequent bowel movements, weight loss and in some people their eyes can start to protrude, and they might develop a visible goitre.

Nutrition support for hyperthyroidism

Assessing whether gluten is problematic in the diet is recommended to assess the autoimmune side of the condition[i]. Also removing iodine[ii] sources and caffeine[iii] has been seen to have some benefits. Make an appointment to see one of our nutritional therapists to find out the root cause of your symptoms. In holistic medicine, it is believed everyone has an individual health journey, so we can consider your unique health history and the functioning of all the body systems in order to create a protocol just for you.

Supplement suggestions for hyperthyroidism

Carnitine[iv] has been shown to be an antagonist of thyroid hormone in tissues therefore supplementing should be considered. Try L-Carnitine 500mg.

· Vitamin D[v] is a key nutrient for modulating the immune system. It is difficult to get this from the diet and only available from sunshine, therefore supplementing October to April may be helpful. Try Liquid Vitamin D3 (50ml).

Low levels of iron have been linked to hyperthyroidism. Organic red meat and fish are good sources of haem iron and green leafy vegetables are sources of non- haem iron. It is best to pair non-haem iron sources with vitamin C, such as lemon juice, to help with iron absorption. Try Spatone (naturally occurring, iron-rich water) or Nano iron (200ml)[vi].

In a similar way to iron, low levels of selenium have been linked to hyperthyroidism. Food sources of selenium are brazil nuts, seafood and organ meats, however supplementing will be beneficial to increase levels. Try Selenium (60 caps)[vii].

Lifestyle recommendations for hyperthyroidism

Stress management is an important part of a hyperthyroidism protocol. Ensure to get regular walks in nature, Epson salt baths, meditation and breathing exercises in your weekly schedule.

Testing options for hyperthyroidism

Thyroid function: it is worth checking thyroid function, as this commonly changes around menopause. Thyroid function is also inextricably linked to reproductive health and hormone production and function. Usually testing for markers such as: TSH (thyroid stimulating hormone), FT3 & FT, thyroid function tests can be sought privately or through your GP. Talk to us for further advice.
