Overactive Thyroid Gland Overview

Another name for Overactive Thyroid Gland is Hyperthyroidism.

What is hyperthyroidism?
A person with hyperthyroidism has an over-active thyroid gland that releases too much thyroid hormone into the bloodstream. Thyrotoxicosis occurs when the thyroid produces very high levels of thyroid hormone, resulting in severe symptoms. Thyroid hormone regulates metabolism. Causes of hyperthyroidism include Grave's disease, increased iodine in the diet, and thyroid tumors. Hyperthyroidism usually occurs between the ages of 30 and 50. With treatment, most people with hyperthyroidism lead a normal life.

What are the symptoms of hyperthyroidism?
Symptoms of hyperthyroidism include absent menstrual periods, anxiety, nervousness, diarrhea, fatigue, heat intolerance, excessive sweating, palpitations, muscle cramps, rapid speech, rapid pulse, weight loss, and neck swelling.

How does the doctor treat hyperthyroidism?
The treatment for hyperthyroidism includes medications to control hyperthyroidism, beta-blockers, and surgery.
