Hi, I recently discovered that my thyroids is quite high 6/4 (hyperthyroidism). The GP order to start taking 25mg of Thyroxine pills. The GP said that it was due a problem with the immune system, but I'd like to verify that as the blood results does not specify anything about it. Is it worth it identify the cause of this problem? And, will improving my diet help me to increase the function of my thyroids? and if so which food is recommended for it? Many Thanks

The answer

Thank you for your question. We feel that you may have slightly confused the issue following your consultation with your GP. If you have been commenced on Thyroxine medication, it would be because you have an underactive thyroid (Hypothyroidism).

Hypothyroidism is when the Thyroid gland is not producing enough of the hormone required to help the body metabolize food.

An underactive Thyroid usually occurs when the immune system, which usually fights infection, attacks the Thyroid gland, therefore causing damage. The Thyroid is then unable to produce enough of the hormone Thyroxine, and that would be the reason that your GP has prescribed this medication for you.

There is no dietary changes that will make any difference to your levels, but please avoid any supplements containing Iodine (such as Kelp).

About your prescribed medication


Levothyroxine is otherwise known as thyroxine, it is a thyroid hormone prescribed to those with an underactive thyroid gland. These hormones work by maintaining a normal rate of metabolism in the body. When the thyroid gland is unable to make normal amounts of thyroxine, the level thyroid hormones in the blood drop. The dosage of levothyroxine prescribed will vary from person to person depending on your thyroid hormone levels. Your dose may be increased gradually over a few weeks until your thyroid hormones fall into the correct range.

How should I take levothyroxine?

It is advisable to take levothyroxine on an empty stomach before breakfast, at least 30 minutes before eating breakfast, drinking caffeine-containing drinks e.g. tea and coffee. This is because all these things can interfere with the absorption of levothyroxine from your gut and make it work less effectively.

You may need to have regular blood tests to monitor your thyroid hormone levels while taking levothyroxine; this helps your doctor to prescribe the correct dose to get your thyroid hormones into the normal range.
