The thyroid gland is located in the anterior part of the windpipe. Thyroid hormones called T3 and T4 are secreted from the thyroid gland. The most important task of these hormones is to regulate the body's metabolism. Depending on the thyroid gland secreting less or more hormones than normal, other organs also work fast or slow. For this reason, weight gain or weight loss problems may be encountered. Support is received from nutritional therapy.
