Thyroid disease

Thyroid disease: Introduction

Thyroid disorders are common disorders of the thyroid gland. Thyroid disorders include such diseases and conditions as Graves' disease, thyroid nodules, Hashimoto's thyroiditis, trauma to the thyroid, thyroid cancer and birth defects. These include being born with a defective thyroid gland or without a thyroid gland.

The thyroid gland is located in the front part of the neck, and the thyroid hormone it produces is vital to normal metabolism. Thyroid disorders can cause the thyroid gland to become overactive (hyperthyroidism) or underactive (hypothyroidism). Thyroid disorders are most often due to autoimmune thyroid diseases, such as Graves' disease and Hashimoto's thyroiditis.

The most common thyroid disorders that result in hyperthyroidism include thyroid nodules and Graves' disease. These thyroid disorders lead to overstimulation of the thyroid gland and increased production of thyroid hormone. Increased production of thyroid hormone in these thyroid disorder results in a stimulation or quickening of the body's metabolism and symptoms, such as nervousness, anxiety and hypertension.

Thyroid disorders that result in hypothyroidism include Hashimoto's thyroiditis and birth defects of the thyroid gland. These thyroid disorders result in decreased production or a total lack of production of thyroid hormone. These thyroid disorders result in a slowing of the body's chemical processes and metabolism and symptoms, such as weight gain, fatigue and depression.

Thyroid disorders may also lead to serious, potentially life-threatening complications. For more details on symptoms and complications, refer to symptoms of thyroid disorders.

Thyroid disorders are more common in women than in men. Hashimoto's thyroiditis occurs most often in females between the ages of 30 and 50 years and appears to have a genetic component because it can run in families. People over the age of fifty who have hypertension or atherosclerosis are at risk for hyperthyroidism.

Making a diagnosis of thyroid disorders begins with taking a thorough medical history, including symptoms, and completing a physical examination. A physician or health care provider may feel a smaller or larger than normal thyroid gland in the neck upon exam.

A blood test is performed to determine levels of thyroid stimulating hormone (TSH) and the thyroid hormone thyroxine. High levels of TSH and low levels of thyroxine reveal that the thyroid gland is underactive. This may indicate a diagnosis of Hashimoto's thyroiditis or other diseases or conditions that cause hypothyroidism.

Low levels of TSH and high levels of thyroxine reveal that a thyroid gland is overactive. This may indicate a diagnosis of Graves' disease or other disease or conditions that cause hyperthyroidism.

Other tests may be performed to check for potential complications of thyroid disorders, such as heart disease. These can include blood tests that can reveal hypercholesterolemia, increased liver enzymes, or anemia. A chest X-ray may be done to evaluate the size of the heart.

It is possible that a diagnosis of thyroid disorders can be missed or delayed because early symptoms can be mild or assumed to be associated with other conditions, such as excessive caffeine use, angina, aging or stress.

Treatment of thyroid disorders varies depending on the specific type of thyroid disorder. For more information on treatment, refer to treatment of thyroid disorders....more »
