Thyroid Disorders

What are Thyroid Disorders?

The thyroid is a pair of glands located at the base of the throat. It plays a critical role in hormone production and regulation, as well as the management of metabolic functions. Hormones are released by the pituitary gland located in the brain. The thyroid is part of the endocrine system, which is a network of glands called responsible for coordinating many of your body’s activities. The thyroid gland manufactures hormones that regulate your body’s metabolism. Several different disorders can arise when your thyroid produces too much hormone (hyperthyroidism) or not enough (hypothyroidism).

What are the types of Thyroid Disorders?


Hyperthyroidism is also called Graves’ disease and is a condition where the body’s immune system malfunctions and causes the release of abnormal antibodies. The 2 primary hormones produced are tetraiodothyronine (T4) and triiodothyronine (T3). Hyperthyroidism occurs when too much T4, T3, or both, are made by the thyroid. This condition leads to symptoms like a faster heartbeat, trembling, sweating, and weight loss. 


Hypothyroidism is a condition where the body does not produce enough thyroid hormones. It cause a number of health problems, such as obesity, joint pain, infertility and heart disease.
