What Is Hyperthyroidism Vs Hypothyroidism?

Hyperthyroidism Vs Hypothyroidism

The goal of this article is to provide information about hyperthyroidism vs hypothyroidism. Since the words hyperthyroidism and hypothyroidism sound alike, these thyroid problems can easily be confused - and misused.

Hyperthyroidism This thyroid problem is also known as high thyroid or overactive thyroid. It's a problem which occurs when the thyroid produces too many hormones. The hormones of the thyroid gland affect respiration, digestion and many other important functions of the body, so when something goes wrong and the hormones become unbalanced, it can be a serious health challenge. There are different types of high thyroid conditions. These include:

Graves' disease This happens with abnormal stimulation of the thyroid gland which results in a goiter (a noncancerous enlargement of the thyroid gland). A related type of Graves' disease called Graves opthalmopathy can affect the eyes and result in protruding eyes (sometimes called "bulging eyes"). Additionally, Graves' disease can affect the shins and the tops of the feet by causing raised and thickened skin.

Thyroiditis is inflammation of the thyroid which causes it to release higher than usual amount of hormones. See thyroiditis.

Pituitary adenoma is a tumor of the pituitary gland.

Drug-induced hyperthyroidism can sometimes occur with certain types of medication. One of these is a heart medicine called amiodarone.

Toxic multinodular goiter happens when part of the thyroid produces hormones all by itself. Toxic multinodular goiter is similar to Graves' disease but different because it causes no eye complications and fewer signs of high thyroid activity. 

Hypothyroidism Hypothyroidism is a thyroid problem that occurs when your thyroid fails to produce enough hormones. The condition is also commonly called underactive thyroid or low thyroid. Someone with hypothyroidism exhibits reduced energy levels and tends to be sluggish and listless. Women with this thyroid problem are likely to experience irregular or infrequent menstruation. See thyroid problems in women.

Other symptoms of hypothyroidism include reduced intellectual capability and depression, a hoarse voice, dry skin and hair loss, constipation, puffiness around the eyes and a low tolerance for cold temperatures. Individuals with hypothyroidism are also prone to weight gain even though the condition causes a lower appetite. See thyroid weight loss problems. 

A diagnosis of hypothyroidism usually results from a simple blood test.
