Hyperthyroidism is a condition in which the thyroid gland (located in the front of your neck) is overactive and produces too much thyroid hormone.
Overview and Symptoms
The thyroid gland releases hormones that control your metabolism, breathing, heart rate, nervous system, weight, body temperature, and many other functions in the body.
The main symptoms of hyperthyroidism include:
- rapid heartbeat
- hand tremor
- excessive sweating
- weight loss
- sleep problems
Hyperthyroidism is very treatable with medication or sometimes radioactive iodine therapy to damage the cells that make thyroid hormones. In rare cases, surgery to remove the thyroid may be needed.
