The American Thyroid Association (ATA) is the world’s leading professional association of medical specialists dedicated to education and research to improve thyroid disease prevention, diagnosis and treatment; improving thyroid patient care; and educating the public about thyroid health and diseases.

Prevalence and Impact of Thyroid Disease
More than 12 percent of the U.S. population will develop a thyroid condition during their lifetime.

An estimated 20 million Americans have some form of thyroid disease.
Up to 60 percent of those with thyroid disease are unaware of their condition.
Women are five to eight times more likely than men to have thyroid problems.
One woman in eight will develop a thyroid disorder during her lifetime.
Most thyroid cancers respond to treatment, although a small percentage can be very aggressive.
The causes of thyroid problems are largely unknown.
Undiagnosed thyroid disease may put patients at risk for certain serious conditions, such as cardiovascular diseases, osteoporosis and infertility.
Pregnant women with undiagnosed or inadequately treated hypothyroidism have an increased risk of miscarriage, preterm delivery, and severe developmental problems in their children.
Most thyroid diseases are life-long conditions that can be managed with medical attention.
Facts about the Thyroid Gland and Thyroid Disease
The thyroid is a hormone-producing gland that regulates the body’s metabolism—the rate at which the body produces energy from nutrients and oxygen—and affects critical body functions, such as energy level and heart rate.

The thyroid gland is located in the middle of the lower neck.
Although the thyroid gland is relatively small, it produces a hormone that influences every cell, tissue and organ in the body.
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone. Symptoms include extreme fatigue, depression, forgetfulness, and some weight gain.
Hyperthyroidism, another form of thyroid disease, is a condition causing the gland to produce too much thyroid hormone. Symptoms include irritability, nervousness, muscle weakness, unexplained weight loss, sleep disturbances, vision problems and eye irritation.
Graves’ disease is a type of hyperthyroidism; it is an autoimmune disorder that is genetic and estimated to affect one percent of the population.
