How does the body regulate thyroid stimulating hormone (TSH)?

Thyroid stimulating hormone (TSH), also known as thyrotropin, is produced by the pituitary gland in the brain and causes the thyroid to make thyroid hormone (T4 and T3). The pituitary gland acts like the thermostat in your home and controls how much thyroid hormone is made by making more or less TSH. When there is not enough thyroid hormone in the body, the pituitary makes more TSH, which tells the thyroid to make and release more thyroid hormone. If there is too much thyroid hormone in the body, the pituitary makes less TSH which tells the thyroid to make and release less thyroid hormone. Therefore, when patients are hyperthyroid (overactive thyroid), the TSH level is low and when they are hypothyroid (underactive thyroid), the TSH level is high.
