Hyperthyroidism, also known as an overactive thyroid, happens when your thyroid gland makes too much thyroid hormone. This small, butterfly-shaped gland in your neck controls important body functions like heart rate and body temperature. Too much of these hormones can lead to unpleasant and potentially serious health issues. This condition can affect anyone, but it's much more common in women, especially between the ages of 20 and 40. Common causes include Graves' disease, thyroid nodules, and certain medications. If left untreated, it can lead to complications like eye problems or heart issues. Fortunately, hyperthyroidism is usually treatable. Your doctor will discuss the best treatment plan for you, which may involve medication, radioiodine therapy, or surgery to manage hormone levels and relieve symptoms.
