Hyperthyroidism

Hyperthyroidism, also known as an overactive thyroid, occurs when the thyroid gland produces more thyroid hormone than the body needs. This speeds up the body's metabolism and can cause symptoms such as unintended weight loss, a rapid or irregular heartbeat, increased appetite, nervousness, tremors, sweating, and difficulty sleeping. Common causes include Graves' disease, thyroid nodules, and inflammation of the thyroid gland. With proper diagnosis and treatment — including medication, radioactive iodine therapy, or surgery when needed — hyperthyroidism can be effectively managed.
