Hypothyroidism Normally‚ the thyroid-stimulating hormone (TSH) is produced when the hypothalamus excretes thyrotropin-releasing hormone (TRH). The secretion of TRH triggers the pituitary gland to release TSH. TSH then activates a release of triiodothyronine (T3) and thyroxine (T4)‚ controlling the body’s metabolism. When T3 and T4 levels rise‚ the secretion of TRH and TSH decrease. When thyroid hormone levels decline‚ there is an increase in TRH and TSH secretion (Buttaro‚ Trybulski‚ Bailey‚ & Sandberg-Cook

thyroid gland‚ resulting in overproduction and thus an excess of circulating free thyroid hormones: thyroxine (T4)‚ triiodothyronine (T3) or both. Thyroid hormone is important at a cellular level‚ affecting nearly every type of tissue in the body. It functions as a stimulus for metabolism. Hyperthyroidism‚ considered as the second most common endocrine disorder. It results from an excessive output of thyroid hormones due to abnormal stimulation of the thyroid gland by circulating immunoglobulin. This

Parathyroid glands are located behind thyroid and produce parathyroid hormone in response to the low calcium level stimulating the production of calcium and balancing the amount of calcium in human body. In such a way‚ thyroid generates calcitonin‚ whereas parathyroid glands regulate the level of calcium in human body through production of hormones. 4.
