This gland is located at the base of the neck, below the Adam’s apple. It’s shaped like a butterfly. It is small but plays a vital role in your body. Every aspect of your metabolism is controlled by the hormones it secretes.

How does thyroid and the hormones work?
Despite its small size, the gland secretes two types of hormones: thyroxine (T4) and triiodothyronine (T3). They together affect every cell in the body by controlling the way cells consume energy. That is to say, these hormones help manage your temperature, heart rate and how fast your body consumes carbohydrates, fats and proteins. Besides, the gland can secrete a hormone called calcitonin which helps regulate the amount of calcium in your blood.

What causes hyperthyroidism?
Hyperthyroidism occurs when the thyroid makes too much T4, T3, or both. Hyperthyroidism is usually a problem brought by other disease. For example, Grave’s disease (an autoimmune disorder), Plummer’s disease (toxic multinodular goiter), toxic adenoma and thyroiditis all can lead to this problem.
In addition, other causes of hyperthyroidism include:
excess iodine, a key ingredient in T4 and T3
inflammation of the thyroid, which causes T4 and T3 to leak out of the gland
tumors of the ovaries
benign tumors of the thyroid or pituitary gland
large amounts of tetraiodothyronine taken through food or medication
If you feel dizzy at times, have shortness of breath and irregular heart rate, you stand the risk of getting hyperthyroidism. If so, go to your doctor for help. It is vital that you get timely treatment for your condition.
