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 ...
the patient has congenital hypothyroidism, the thyroid gland is in the normal position in the neck, the size of the thyroid is either normal or atrophic, the serum TSH level is increased, the bioactivity of TSH is intact, and the response of the thyroid gland to TSH stimulati...
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 ...

The clinical course of Graves' disease is described in an 8 year old girl with high thyroid-stimulating immunogloblin (TSI) and thyrotropin-binding inhibition immunoglobulin (TBII) titers, 6,421% and 87.8%, respectively. She had three cycles of alternating hyper- and hypothyroidism during two ...
