Description

Too much thyroid hormone. The thyroid gland is located at the base of the neck and produces thyroid hormone and calcitonin. Thyroid hormone is an integral controller of the body's metabolism. Hyperthyroidism (too much thyroid hormone) occurs when the thyroid gland produces an excessive amount of thyroid hormone, or too much thyroid hormone medication is ingested.

Symptoms

Rapid heart rate, elevated blood pressure, diarrhea, weight loss, tremors, apprehension, fever, vomiting, nervousness, heat intolerance, increased appetite, fatigue, prominent (bulging) eyes. A thyroid storm may also occur which causes sudden intensification of symptoms. Thyroid storm occurs when your thyroid gland suddenly releases large amounts of thyroid hormone in a short period of time.

Tests

Treatment

Treatment includes: propylthiouracil (PTU), methimazole (Tapazole), beta-blocker medications, radioactive iodine (which destroys the thyroid gland), and/or surgery.
