Ailments and Situations - Hypothyroidism - Causes

 

Causes:

The occurrence of an under-active thyroid is quite common.

Historically, hypothyroidism was caused by iodine deficiency. Iodine is needed to ensure proper production of hormones. A decrease of iodine intake can also lead to the formation of a goiter.

Recently, it is believed the most common reason for hypothyroidism is due to an autoimmune disease known as Hashimoto's disease. In these cases, the body becomes allergic to its own thyroid gland and forms antibodies against it. These antibodies form and bind to the thyroid, prohibiting the secretion of hormone.
