pajzsmirigyhormon

Pajzsmirigyhormon, also known as thyroid-stimulating hormone (TSH), is a hormone produced by the pituitary gland in the brain. It plays a crucial role in regulating the thyroid gland, which is responsible for producing hormones that control metabolism, heart rate, and body temperature. TSH stimulates the thyroid gland to produce thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). These hormones are essential for various physiological processes, including growth, development, and maintaining normal body functions.

TSH levels are typically regulated by the amount of thyroid hormone in the blood. When thyroid hormone levels are low, the pituitary gland releases more TSH to stimulate the thyroid gland to produce more hormones. Conversely, when thyroid hormone levels are high, the pituitary gland releases less TSH. This feedback mechanism helps maintain a delicate balance of thyroid hormones in the body.

Abnormal levels of TSH can indicate various health conditions. Elevated TSH levels may suggest hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Conversely, low TSH levels can indicate hyperthyroidism, where the thyroid gland produces too many hormones. Both conditions can lead to symptoms such as fatigue, weight changes, and changes in heart rate. Regular monitoring of TSH levels is important for diagnosing and managing thyroid disorders.
