Treating mild hypothyroidism: Benefits still uncertain

Your thyroid, a tiny, butterfly-shaped gland located in front of your windpipe (trachea) and below your voice box (larynx) can have a profound impact on your health and well-being. Throughout life, your thyroid is constantly producing hormones that influence your metabolism. These hormones affect your mood, energy, body temperature, weight, heart, and more. A brief overview of hypothyroidism Your thyroid produces two kinds of thyroid hormones: T4, or thyroxine, and T3, or triiodothyronine. These hormones influence every cell, tissue, and organ in your body, from your muscles, bones, and skin to your digestive tract, brain, and heart, by controlling how fast and efficiently cells convert nutrients into energy — a chemical activity known as metabolism. The thyroid gland is under the influence of the pituitary gland. No larger than a pea and located at the base of the brain, the pituitary gland controls your thyroid’s production of thyroid hormone by releasing thyroid stimulating hormone (TSH). TSH levels in your bloodstream rise or fall depending on whether there is enough thyroid hormone made to meet your body’s needs. Higher levels of TSH prompt the thyroid to produce more thyroid hormone, while lower levels signal the thyroid to produce less. Hypothyroidism occurs when the thyroid fails to produce enough thyroid hormone to meet the body’s needs, thereby slowing metabolism. In someone with overt hypothyroidism, thyroid hormone levels are below normal and TSH levels ar...
