Thyroid stimulating hormone (Tsh) is a peptide hormone that is secreted by the pituitary gland which is located at the base of the brain. It's main function is to stimulate the thyroid gland to yield thyroid hormones, thyroxine or T4 and triiodothyronine or T3. Tsh is also responsible for maintaining the levels of thyroid hormones in the body.
The levels of Tsh in the blood can be used as a measure of execution of thyroid gland. If there is a qoute with the thyroid gland, this will reflect on the Tsh levels in the body. Therefore, in order to decree an basal thyroid disorder, a doctor normally orders a Tsh blood test.
There is a normal range of Tsh which is an indication of an active or salutary thyroid gland, but any deviation from the normal range is a sign of under-active or thyroid disorder. The normal range of Tsh is 0.4 - 4.0 ml U/L. Any other value which is above or below this normal range indicates that you have a thyroid problem.
High Tsh Levels
If your blood test results indicate high Tsh levels, this shows that your thyroid gland is not producing adequate thyroid hormones required by the body. This condition is known as hypothyroidism. When this happens, the pituitary gland then releases more Tsh hormones to stimulate the thyroid gland to yield more thyroid hormones.
A high level of Tsh is an important indication of malfunctioning of thyroid gland. This also indicates that there may be problems with the pituitary gland. Other factors that may cause high levels of Tsh in the body are surgery, medication and tumor of the pituitary gland.
Low Tsh Levels
Low Tsh blood tests succeed implies that you have a hyperactive thyroid gland which often produces excess thyroid hormones. This condition is known as hyperthyroidism. A low-level of Tsh is also an indication of problems with the pituitary gland.
A Tsh blood test succeed is very important in the diagnosing of thyroid problems. A test which is above or below the normal range of Tsh is an indication of deficient or excess thyroid hormones in the body. Therefore it is very important to say normal level of Tsh. The rehabilitation for abnormal Tsh level depends on either you are suffering from hypothyroidism or hyperthyroidism. Once you are diagnosed, it is important to consult your doctor for permissible rehabilitation and medication.
