What is hypothyroidism? Signs and Symptoms

What is the thyroid?

The thyroid is a butterfly-shaped endocrine gland usually located in the lower front of the neck below the larynx (the voice box). The thyroid’s job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body. Thyroid hormone helps the body use energy, stay warm and keep the brain, heart, muscles, and other organs working as they should. The main hormone made by the thyroid is thyroxine, also called T4 because it contains four iodine molecules.

Small amounts of another and more potent thyroid hormone containing three iodine molecules, triiodothyronine (T3) are also made by the thyroid gland. However, most of the T3 in the blood is made from T4 in other body tissues. Thyroid hormones control the way every tissue in your body uses energy. They are essential to help each cell in your body’s tissue and organs work right. For example, thyroid hormone controls the body’s temperature, heart rate, blood pressure, and the rate at which food is turned into energy (metabolism).
