Also known as: Hyperthyroidism (Overactive Thyroid)
Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone, causing the body's metabolism to speed up. The most common cause is Graves' disease, an autoimmune condition. Symptoms can affect many body systems and may initially be subtle, but the condition is very treatable with medications, radioactive iodine therapy, or surgery.
People with Hyperthyroidism often experience the following symptoms.
Certain factors may increase your likelihood of developing Hyperthyroidism.
See a doctor if you experience unexplained weight loss, a rapid or pounding heartbeat, excessive sweating, or significant changes in mood or energy levels. Seek emergency care for thyroid storm symptoms, which include very rapid heart rate, high fever, confusion, and agitation. This is a rare but serious complication that requires immediate treatment.
