Part 1: INTRODUCTION TO HYPERTHYROIDISM
Hyperthyroidism is a large topic so we have split it into four manageable sized portions.
This page introduces hyperthyroidism. Subsequent pages are listed at the bottom which address more specific details of making the diagnosis of hyperthyroidism, the causes of hyperthyroidism, and different treatment options available for hyperthyroidism.

In healthy people, the thyroid makes just the right amounts of two hormones, T4 and T3, which have important actions throughout the body. These hormones regulate many aspects of our metabolism, eventually affecting how many calories we burn, how warm we feel, and how much we weigh. In short, the thyroid "runs" our metabolism. These hormones also have direct
Although there are several different causes of hyperthyroidism, most of the symptoms that patients experience are the same regardless of the cause (see the list of symptoms below). Because the body's metabolism is increased, patients often feel hotter than those around them and can slowly lose weight even though they may be eating more. The weight issue is confusing sometimes since some patients actually gain weight because of an increase in their appetite. Patients with hyperthyroidism usually experience fatigue at the end of the day, but have trouble sleeping. Trembling of the hands and a hard or irregular heartbeat (called palpitations) may develop. These individuals may become irritable and easily upset. When hyperthyroidism is severe, patients can suffer shortness of breath, chest pain, and muscle weakness. Usually the symptoms of hyperthyroidism are so gradual in their onset that patients don't realize the symptoms until they become more severe. This means the symptoms may continue for weeks or months before patients fully realize that they are sick. In older people, some or all of the typical symptoms of hyperthyroidism may be absent, and the patient may just lose weight or become
Some of the symptoms of hyperthyroidism such as tremor and palpitations which are caused by excess thyroid hormone acting on the cardiac and nervous system can be improved within a number of hours by medications called beta-blockers (e.g., propranolol; Inderal). These drugs block the effect of the thyroid hormone but don't have an effect on the thyroid itself, thus Beta-blockers do not cure the hyperthyroidism and do not decrease the amount of thyroid hormone being produced, they just prevent some of the symptoms. For patients with temporary forms of hyperthyroidism (thyroiditis or taking excess thyroid medications), beta blockers may be the only treatment required. Once the thyroiditis (inflammation of the thyroid gland) resolves and goes away, the patient can be taken off of these
