What is hyperthyroidism?

Hyperthyroidism is a clinical condition determined by the overactivity of the thyroid gland positioned in the neck front. The thyroid gland is responsible for producing hormones that regulate several bodily functions, such as metabolism, heart rate, and body temperature.

In hyperthyroidism, the thyroid gland forms a huge amount of thyroid hormones, significantly triiodothyronine (T3) and thyroxine (T4). This excessive hormone formation elevates the body's metabolism, causing a wide range of symptoms and potential complications. Timely diagnosis and medical professionals intervention is required for the suitable treatment.
