What is Hyperthyroidism?

Hyperthyroidism is a medical condition typically characterized by an excessive secretion of the thyroid hormone by the thyroid glands in the body or simply put ‘’overactive thyroid”. The thyroid is home to two major hormones in the body and these are the “thyroxine (T-4) and the triiodothyronine (T-3).

Collectively, these two hormones affects how the body works as they can play key roles in body metabolism. When the thyroid produces too much T3 ,T4 hormones or even both, it can speed up your body’s systems and lead to distress.

A Timely diagnosis and treatment can relieve symptoms and help prevent further complications. The most reliable method of diagnosis of hyperthyroidism is to simply undergo a thyroid function test to check for levels of the thyroid stimulating hormone (TSH).

Cause of Hyperthyroidism

Apart from the general knowledge that we have of hyperthyroidism being simply as a result of the over production of the thyroid hormones, there are however underlying conditions that can pre-dispose one to this condition.

The most common cause   is an auto immune disorder  known  as “Graves  disease”. Genetics largely determines whether one can be affected by graves disease.   In graves disease, the immune system is seen to attack the thyroid gland which results in the production of too much thyroid hormones. 

Other known causes includes excess iodine, thyroiditis (inflammation of the thyroid), benign nodules, toxic adenoma, tumors of the ovaries/testes.
