Graves Disease and Hyperthyroidism
An autoimmune disorder, Grave's disease is the most common cause of hyperthyroidism (overactivity of the thyroid gland).
In hyperthyroidism, the thyroid gland produces too much of the hormones thyroxine (T4) and triiodothyronine (T3) — hormones that control body metabolism. Controlling the body's metabolism is critical for mood regulation, weight, and mental and physical energy levels.
Graves disease – also known as toxic diffuse goiter – is caused by an abnormal immune system response that makes the thyroid gland produce too much thyroid hormones. Even though more common in women over age 20, Graves disease can occur at any age and may affect men too.
Treatment of Graves disease can be one or more of the following: anti-thyroid medications, radioactive iodine and surgery (thyroidectomy or removal of the thyroid gland).
