How to treat hyperthyroidism

#howto #treat #hyperthyroidism #gravesdisease #thyroidawareness #video If you have an overactive thyroid (hyperthyroidism), your thyroid gland produces too much of the thyroid hormones. This results in high levels of the 2 main thyroid hormones, triiodothyronine (also called T3) and thyroxine (also called T4) in your body. There are a number of conditions that can cause your thyroid to become overactive. About 3 in every 4 people with an overactive thyroid gland have a condition called Graves' disease. Graves' disease is an autoimmune condition where your immune system mistakenly attacks your thyroid which causes it to become overactive. The cause of Graves' disease is unknown, but it mostly affects young or middle-aged women and often runs in families. Smoking can also increase your risk of getting it.
