Hypothyroidism Hypothyroidism, or low thyroid and sometimes hypothyreosis, is a common disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormone.It can cause a number of symptoms, such as poor ability to tolerate cold, a feeling of tiredness, and weight gain.In children, hypothyroidism leads to delays in growth and intellectual development, which is called cretinism in severe cases.orldwide, too little iodine in the diet is the most common cause of hypothyroidism. In countries with enough iodine in the diet, the most common cause of hypothyroidism is the autoimmune condition Hashimoto's thyroiditis.

hypothyroidism Myxedema coma. If untreated, hypothyroidism can eventually cause anemia, a low body temperature, and heart failure. This situation may progress to confusion, stupor, or coma (myxedema coma). Myxedema coma is a life-threatening complication in which breathing slows, seizures occur, and blood flow to the brain decreases.

- Hyperthyroidism (Definition) Hypothyroidism is a medical condition that lowers the level of thyroid hormone to a point where the patient has a marked decrease in overall health. Often the patient does not notice the loss of thyroid hormone for several weeks or more.

Hypothyroidism (Underactive Thyroid) Hypothyroidism, also called underactive thyroid disease, is a common disorder. With hypothyroidism, your thyroid gland does not make enough thyroid hormone. The thyroid gland is located in the front lower part of your neck. Hormones released by the gland travel through your bloodstream and affect nearly every part of your body, from your heart and brain, to your muscles and skin.

- When maternal TSH is elevated, measurement of serum FT4 concentration is necessary to classify the patient's status as either subclinical (SCH) or overt hypothyroidism (OH). SCH is defined as a serum TSH between 2.5 and 10 mIU/L with a normal FT4 concentration. Women with a TSH concentration above the trimester-specific reference interval with a decreased FT4, and all women with a TSH concentration above 10.0 mIU/L irrespective of the level of FT4 are also considered to have OH.

Chronic Thyroiditis (Hashimoto's Disease)  In-Depth Report Subclinical hypothyroidism (mildly underactive thyroid) is a condition in which thyrotropin (TSH) levels have started to increase in response to an early decline in T4 levels in the thyroid. However, blood tests for T4 are still normal. The person may have mild symptoms (usually slight fatigue) or none at all.

Practice Essentials Background. Hypothyroidism is a common endocrine disorder resulting from deficiency of thyroid hormone. It usually is a primary process in which the thyroid gland is unable to produce sufficient amounts of thyroid hormone.n the United States and other areas of adequate iodine intake, autoimmune thyroid disease (Hashimoto disease) is the most common cause of hypothyroidism; worldwide, iodine deficiency remains the foremost cause. The image below depicts the hypothalamic-pituitary-thyroid axis.

Dangerous TSH levelsAppleJacs May 06, 2007 Severe untreated hypothyroidism can cause a variety of issues within the body. Your thyroid controls your body temperature, metabolism, heart rate, and other body functions. High TSH does not, itself, cause symptoms. TSH is a pituitary hormone produced to stimulate the thyroid to make hormones. If the thyroid does not respond to the demand, the pituitary continues to pump out TSH. Your symptoms would have been due to lack of adequate hormones, plus the actual size/condition of your thyroid.

Wilmsâ tumour, home haemodialysis and kidney transplants Congenital hypothyroidism. Congenital hypothyroidism is a disorder affecting the thyroid gland, which is in the neck. The thyroid gland produces a hormone (chemical substance) called thyroxine, which is needed for normal growth and development. If the thyroid gland does not produce enough thyroxine, it causes hypothyroidism. If the disorder is present at birth, it is called congenital hypothyroidism.

hypothyroidism 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.

Subclinical Hypothyroidism: Deciding When to Treat This state—an elevated TSH level with a normal free T 4 level—is referred to as subclinical hypothyroidism. The term “subclinical” may not be strictly correct, since some of these patients may have clinical symptoms, but no better term has been proposed.

Hypothyroidism In overt primary hypothyroidism, TSH levels are high and T4 and T3 levels are low. Overt hypothyroidism may also be diagnosed in those who have a TSH on multiple occasions of greater than 5mIU/L, appropriate symptoms, and only a borderline low T4. It may also be diagnosed in those with a TSH of greater than 10mIU/L.

Hyperthyroidism Hyperthyroidism, also known as over active thyroid and hyperthyreosis, is the condition that occurs due to excessive production of thyroid hormone by the thyroid gland. Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism.hyroid storm is a severe form of thyrotoxicosis characterized by rapid and often irregular heart beat, high temperature, vomiting, diarrhea, and mental agitation. Symptoms may be unusual in the young, old, or pregnant.
