Jul 25, 2022 · Thyroid-stimulating hormone, commonly called TSH and also referred to as thyrotropin, is a hormone that your pituitary gland releases to trigger your thyroid to produce and release its own hormones — thyroxine (T4) and triiodothyronine (T3). These two hormones are essential for maintaining your body’s metabolic rate — the speed at which ...
Aug 9, 2022 · Thyroid-stimulating hormone (TSH) is a hormone that prompts your thyroid gland to produce the thyroid hormones triiodothyronine (T3) and thyroxine (T4). The hypothalamus , located in the brain, constantly monitors your blood for levels of thyroid hormones, and if it detects too little, it triggers the pituitary gland , also located in the brain ...

Feb 15, 2022 · Your body controls your thyroid hormone (T3 and T4) levels through a complex feedback loop. Your hypothalamus releases thyrotropin-releasing hormone (TRH), which triggers your pituitary gland to release thyroid-stimulating hormone (TSH), which stimulates your thyroid to release T3 and T4.
Thyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, or abbreviated 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.
May 14, 2024 · When released by the pituitary gland—a small gland located at the base of the brain—TSH stimulates the thyroid to produce more thyroid hormone. How TSH Levels Change. TSH levels seem counterintuitive. A high TSH suggests an underactive thyroid gland, while low TSH levels indicate an overactive thyroid. TSH and thyroid hormones are different things.
A TSH test is used to find out how well your thyroid is working. It can tell if you have hyperthyroidism (too much thyroid hormone) or hypothyroidism (too little thyroid hormone) in your blood. But a TSH test can't show what is causing a thyroid problem.
