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.
A thyroid goiter occurs when your thyroid gland grows larger than normal. Your thyroid makes hormones that help control your body temperature, heart rate, and growth. They also control how fast your body uses food for energy. The amount of thyroid hormones in your body may increase, decrease, or both when you have a goiter.
