You can experience symptoms of hypothyroidism with normal TSH levels. Learn more about when and how this can occur.
High TSH levels indicate low levels of thyroid hormone activity. Inadequate thyroid hormone production leads to hypothyroidism and associated symptoms including weight gain. Low TSH levels indicate high levels of thyroid hormone activity, most likely due to too much thyroid hormone production or hyperthyr...
Less often, a lack of TSH produced by the pituitary gland (due to dysfunction) can lead to low levelsof thyroid hormone in the blood—a condition known as central hypothyroidism. This is an exception to the general rule that hypothyroidism is associated with a high TSH. Central hypothyroidism ...
A TSH blood test can be done quickly by health care professionals, and is used to identify abnormal hormone levels in the blood. Abnormal levels of thyroid-stimulating hormone might indicate a thyroid problem. High TSH levels typically indicate hypothyroidism, which means thethyroid glandis underacti...
THYROID diseasesPrimary hypothyroidism (PHT) is associated with an increased risk for the development of atherosclerosis (AS) and other cardiovascular disorders. PHT induces atherosclerosis (AS) through the induction of endothelial dysfunction, and insulin resistance (IR). PHT promotes vasoconstriction and...
There are two types of TSH receptor antibodies (TRAb); thyroid stimulating antibody (TSAb) and TSH-stimulation blocking antibody (TSBAb). TSAb causes Graves' hyperthyroidism. TSBAb causes hypothyroidism. Both TSAb and TSBAb block TSH-binding to thyroid cells as TSH receptor antibodies (TRAb). TSBAb...

hypothyroidism. In primary hypothyroidism, where there is impaired production of thyroid hormones, the TSH level is typically highly elevated. In secondary or tertiary hypothyroidism where the thyroid hormones are low as a consequence of pituitary or hypothalamic lesions, the TSH level is usually low....
The protein encoded by this gene is the beta subunit of thyroid stimulating hormone. Mutations in this gene are associated with congenital central and secondary hypothyroidism and Hashimoto's thyroiditis. Alternative splicing of this gene results in multiple transcript variants. 关键字: Anti-TSHB ...
Stimulating and blocking thyroid-stimulating hormone (TSH) receptor autoantibodies from patients with Graves' disease and autoimmune hypothyroidism have ve... The distinct biological properties of TSH receptor (TSH-R) autoantibodies (TRAbs) from patients with Graves' disease (GD) are yet unexplained on...
