Hypothyroidism happens when your thyroid gland doesn't make enough thyroid hormone. Thyroid hormone controls the way your body uses energy. A low thyroid level can make you feel tired and weak.
Medicine can correct your thyroid level. Most people need to keep taking the thyroid medicine throughout their lives.
