Factors That Affect Your Thyroid Function

In my second book, Living The Healthy Life, I talk about how the thyroid is at the core of all bodily functions. By controlling the metabolic function, it controls everything.


Here are some factors that can interrupt thyroid function – even I had no idea about some of them until hypothyroidism became a part of my life!

  • Stress and adrenal glands. High cortisol levels can reduce the conversion of T4 to T3, which is essential.
  • Hormone levels. High oestrogen can interfere with thyroid hormone production.
  • Leaky gut syndrome. When your gut lining is ‘broken’ (due to stress, a poor diet or allergies), food fragments can escape into the bloodstream, causing the body to react with an autoimmune response. This, in turn, can lead to the rise of thyroid antibodies.
  • A high intake of iodine (including iodine supplements) can, in some cases, ‘feed’ the thyroid antibodies.
  • Environmental toxins and heavy metals such as mercury toxicity.
  • Gut parasites.
  • Mineral levels. The body needs the right amount of iodine, selenium and iron to make thyroid hormones – not too little, and not too much.
  • Pituitary gland function. That peanut-sized gland in your brain is a powerhouse. Stress can cause it to slow down.
  • Vitamin D levels. This plays a role in immunity, and low vitamin D levels are associated with autoimmune conditions.
  • Low carb diets. A lack of carbohydrates can put stress on the thyroid as well as the adrenal glands.
  • The state of your immune system. Particularly if you have another autoimmune condition or a history of picking up colds and flu easily.
  • Experts say gluten can trigger thyroid diseases, especially Hashimoto’s.
  • Goitrogenic foods. When eaten in excess or in their raw state, foods like cauliflower, broccoli, kale and soy can affect the thyroid.
