Hyperthyroidism is caused by hypersecretion of thyroid hormones T3 and T4, which increases the basal metabolic rate. Common causes include Graves' disease, thyroid tumors, and toxic multinodular goiter. Symptoms include nervousness, sweating, tremors, increased heart rate, and weight loss. Diagnosis involves testing thyroid hormone levels in blood and ultrasound or scan of the thyroid gland. Treatment options include anti-thyroid medications, surgery to remove part or all of the thyroid gland, and maintaining a high calorie diet.

- 7. Graves' disease. is the most common cause of hyperthyroidism. It is an immune system disorder. The body produces antibodies that cause the thyroid to make and release too much thyroid hormone. Thyroid tumor. A noncancerous thyroid tumor may make and secrete increased amounts of thyroid hormones. Toxic multinodular goiter. The thyroid gland is enlarged with many noncancerous thyroid tumors. They secrete increased amounts of thyroid hormone. Note:- very rare situations, excess thyroid hormone can come from a source outside the thyroid.
