Thyroid-stimulating hormone From Wikipedia, the free encyclopedia. Thyroid-stimulating hormone (also known as thyrotropin, TSH, or hTSH for human TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T 4), and then triiodothyronine (T 3) which stimulates the metabolism of almost every tissue in the body.levated reverse T 3 (RT 3) together with low-normal TSH and low-normal T 3, T 4 values, which is regarded as indicative for euthyroid sick syndrome, may also have to be investigated for chronic subacute thyroiditis (SAT) with output of subpotent hormones.

What is Takotsubo cardiomyopathy? Takotsubo Cardiomyopathy: Causes, Symptoms and Treatment. Takotsubo cardiomyopathy, also known as stress cardiomyopathy, apical ballooning, or broken heart syndrome, is a temporary heart condition. It has the same symptoms as a heart attack but is not caused by any underlying cardiovascular disease. Symptoms include chest pain, difficulty breathing, and sudden loss of consciousness. Takotsubo cardiomyopathy most often affects women between the ages of 61-76. The condition commonly occurs immediately after experiencing extreme emotional or physical stress.

Hyperthyroidism Thyroid crisis (storm) is a sudden worsening of hyperthyroidism symptoms that may occur with infection or stress. Fever, decreased alertness, and abdominal pain may occur. Patients need to be treated in the hospital.

Causes and Risk Factors of Hyperthyroidism Hyperthyroidism—sometimes referred to as thyrotoxicosis—is a condition where your thyroid is overactive, and overproducing thyroid hormone. Graves' disease is an autoimmune disease that usually causes you to become hyperthyroid.

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.

- Thyrotoxicosis. Thyrotoxicosis means an excess of thyroid hormone in the body. Having this condition also means that you have a low level of thyroid stimulating hormone, TSH, in your bloodstream, because the pituitary gland senses that you have “enough” thyroid hormone.yperthyroidism, also referred to as an overactive thyroid is the most common cause of thyrotoxicosis and, occurs when your thyroid gland produces too much thyroid hormone.

Thyroxine Thyroxine, also called 3,5,3′,5′-tetraiodothyronine, or T 4, one of the two major hormones secreted by the thyroid gland (the other is triiodothyronine). Thyroxine’s principal function is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues in the body.

Useful For See Thyroid Function Ordering Algorithm in Special Instructions. Thyroperoxidase (TPO) is an enzyme involved in thyroid hormone synthesis, catalyzing the oxidation of iodide on tyrosine residues in thyroglobulin for the synthesis of triiodothyronine and thyroxine (tetraiodothyronine).

Thyroiditis Thyroiditis is a general term that refers to “inflammation of the thyroid gland”. Thyroiditis includes a group of individual disorders causing thyroidal inflammation but presenting in different ways. For example, Hashimoto’s thyroiditis is the most common cause of hypothyroidism in the United States. Postpartum thyroiditis, which causes temporary thyrotoxicosis (high thyroid hormone levels in the blood) followed by temporary hypothyroidism, is a common cause of thyroid problems after the delivery of a baby.

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.

Medical Care Radiation thyroiditis is rare, but it may occur and exacerbate thyrotoxicosis. Long-term follow-up is mandatory for all patients. One concern with the use of radioiodine in persons with Graves disease is its controversial potential for exacerbating existing Graves ophthalmopathy. However, the presence of ophthalmopathy should not influence the choice of therapy for hyperthyroidism.

thyroxine (T4) [thi-rok´sin] a thyroid hormone that contains iodine and is a derivative of the amino acid tyrosine, occurring naturally as l-thyroxine; its chemical name is tetraiodothyronine. It is formed and stored in the thyroid follicles as thyroglobulin and released from the gland by the action of a proteolytic enzyme.

Hypothyroidism vs Hyperthyroidism Differences in Signs, Symptoms This slows the metabolic activity within the body. Hyperthyroidism (thyrotoxicosis) is the increased activity of the thyroid gland (overactive thyroid) resulting in an increase in the level of thyroid hormones circulating in the blood. This speeds up the metabolic activity within the body.

Hypothyroidism and Hyperthyroidism Thyrotoxicosis is a clinical condition resulting from the action of excess thyroid hormone on tissues. The term hyperthyroidism is usually reserved for thyrotoxicosis caused by excessive production of thyroid hormone (Boxes 4 and 5). Other forms of thyrotoxicosis include thyrotoxicosis factitia and those associated with different forms of thyroiditis.

thyroid crisis It usually occurs in a patient whose thyrotoxicosis treatment is inadequate, and the paroxysm is triggered by a stressful infection or injury. If untreated, the crisis is often fatal. Also called thyroid storm, thyrotoxic crisis.
