Hypothyroidism (underactive thyroid) Overview. Hypothyroidism (underactive thyroid) is a condition in which your thyroid gland doesn't produce enough of certain important hormones. Women, especially those older than age 60, are more likely to have hypothyroidism. Hypothyroidism upsets the normal balance of chemical reactions in your body.
The thyroid produces hormones that influence every organ, tissue, and cell in the body. Thyroid hormones also control heart rate, body weight, body temperature, energy level, muscle strength and menstrual regularity. When the thyroid becomes faulty or malfunctions, metabolic disorders occur.
