Tertiary hypothyroidism definition of tertiary hypothyroidism by Medical dictionary. Hypothyroidism Definition. Hypothyroidism, or underactive thyroid, develops when the thyroid gland fails to produce or secrete as much thyroxine (T4) as the body needs. Because T4 regulates such essential functions as heart rate, digestion, physical growth, and mental development, an insufficient supply of this hormone can slow life- sustaining processes, damage organs and tissues in every part of the body, and lead to life- threatening complications. Description. Hypothyroidism is one of the most common chronic diseases in the United States. Symptoms may not appear until years after the thyroid has stopped functioning and they are often mistaken for signs of other illnesses, menopause, or aging.

Although this condition is believed to affect as many as 1. Nicknamed "Gland Central" because it influences almost every organ, tissue, and cell in the body, the thyroid is shaped like a butterfly and located just below the Adam's apple. The thyroid stores iodine the body gets from food and uses this mineral to create T4. Low T4 levels can alter weight, appetite, sleep patterns, body temperature, sex drive, and a variety of other physical, mental, and emotional characteristics. There are three types of hypothyroidism.

The most common is primary hypothyroidism, in which the thyroid doesn't produce an adequate amount of T4. Secondary hypothyroidism develops when the pituitary gland does not release enough of the thyroid- stimulating hormone (TSH) that prompts the thyroid to manufacture T4. Adult Swim Off The Air. Tertiary hypothyroidism results from a malfunction of the hypothalamus, the part of the brain that controls the endocrine system. Drug- induced hypothyroidism, an adverse reaction to medication, occurs in two of every 1. Hypothyroidism is at least twice as common in women as it is in men.

Although hypothyroidism is most common in women who are middle- aged or older, the disease can occur at any age. Newborn infants are tested for congenital thyroid deficiency (cretinism) using a test that measures the levels of thyroxine in the infant's blood. Treatment within the first few months of life can prevent mental retardation and physical abnormalities. Older children who develop hypothyroidism suddenly stop growing. Factors that increase a person's risk of developing hypothyroidism include age, weight, and medical history.

Women are more likely to develop the disease after age 5. Obesity also increases risk. A family history of thyroid problems or a personal history of high cholesterol levels or such autoimmune diseases as lupus, rheumatoid arthritis, or diabetes can make an individual more susceptible to hypothyroidism. Causes and symptoms. Hypothyroidism is most often the result of Hashimoto's disease, also known as chronic thyroiditis (inflammation of the thyroid gland).

In this disease, the immune system fails to recognize that the thyroid gland is part of the body's own tissue and attacks it as if it were a foreign body. The attack by the immune system impairs thyroid function and sometimes destroys the gland. Other causes of hypothyroidism include: Radiation. Radioactive iodine used to treat hyperthyroidism (overactive thyroid) or radiation treatments for head or neck cancers can destroy the thyroid gland. Surgery. Removal of the thyroid gland because of cancer or other thyroid disorders can result in hypothyroidism.

Viruses and bacteria. Infections that depress thyroid hormone production usually cause permanent hypothyroidism. Medication. Nitroprusside, lithium, or iodides can induce hypothyroidism. Because patients who use these medications are closely monitored by their doctors, this side effect is very rare. Pituitary gland malfunction.

This is a rare condition in which the pituitary gland fails to produce enough TSH to activate the thyroid's production of T4. Congenital defect. One of every 4,0. Diet. Because the thyroid makes T4 from iodine drawn from food, an iodine- deficient diet can cause hypothyroidism.

Adding iodine to table salt and other common foods has eliminated iodine deficiency in the United States. Certain foods (cabbage, rutabagas, peanuts, peaches, soybeans, spinach) can interfere with thyroid hormone production. Environmental contaminants. New York Summer Courses For Adults. Certain man- made chemicals—such as PCBs—found in the local environment at high levels may also cause hypothyroidism.

Hypothyroidism is sometimes referred to as a "silent" disease because early symptoms may be so mild that no one realizes anything is wrong. Untreated symptoms become more noticeable and severe, and can lead to confusion and mental disorders, breathing difficulties, heart problems, fluctuations in body temperature, and death.
