Thyroid

The thyroid gland is found in the neck. It produces hormones that are released into the bloodstream to control the body's growth and metabolism. These hormones are called thyroxine and triiodothyronine. They affect processes such as heart rate and body temperature, and help convert food into energy to keep the body going.

Thyroid hormone

Thyroid hormone tablets can be taken to keep your thyroid levels normal. Hypothyroidism is treated with tablets called levothyroxine (often referred to as thyroxine). The aim is to cure the symptoms of hypothyroidism by replacing the lack of thyroid hormones in your blood.

Thyroid-stimulating hormone (TSH)

Thyroid-stimulating hormone (TSH) is made in the pituitary gland in your brain and controls the production of thyroxine and triiodothyronine. When the level of thyroxine and triiodothyronine in your blood are normal, your pituitary gland stops releasing TSH. When the level of thyroxine or triiodothyronine drops, the pituitary gland produces more TSH to boost the level.

Thyroid-stimulating hormone (TSH) test

This involves taking a sample of blood and testing it for levels of thyroid-stimulating hormone (TSH) and thyroxine and triiodothyronine (the thyroid hormones)

Thyroidectomy
