Hypothyroidism

Hypothyroidism is most commonly a result of an autoimmune condition known as Hashimoto’s thyroiditis, in which the body’s own immune cells attack and destroy the thyroid gland. Since the activity of the thyroid gland is controlled by other hormones from the pituitary gland and the hypothalamus of the brain, defects in these areas can also cause underactivity of the thyroid gland. Previous surgeries on the thyroid or a history of irradiation to the neck are other causes of hypothyroidism.

Symptoms of hypothyroidism can be mild or severe, but are often very subtle. People with a mild form of the condition may not have any symptoms at all. The most serious form of hypothyroidism is called myxedema, which can lead to coma and even death. An underactive thyroid gland affects all organs and functions within the body, leading to both physical and emotional symptoms.
