Hyperthyroidism happens when there’s too much thyroid hormone in your body. This condition is also called thyrotoxicosis. An overactive or enlarged thyroid gland may produce more thyroid hormone.
Your thyroid is a butterfly-shaped gland at the front of your neck. It produces thyroid hormones called T3 and T4. These hormones help your body use energy, help balance body temperature, and help your brain, heart, and other organs function properly. In some cases, thyroid cancers may also cause an overactive thyroid.
Hyperthyroidism can be easily confused with other health problems. Its range of symptoms includes sudden weight loss, increased appetite, anxiety, irritability and nervousness, mood changes, difficulty sleeping, feeling hot, sweating, fast heartbeat or pounding heart, fatigue or tiredness, muscle weakness, hand tremor or slight shaking, more frequent or other changes in bowel movements, skin thinning, fine, brittle hair, menstruation changes, enlarged thyroid gland (goiter), swelling at base of your neck, eye changes, and red, thick skin on upper feet and shins.
