Hypothyroidism occurs when the thyroid gland produces too few thyroid hormones. The symptoms of this may include experiencing fatigue, gaining weight for no purpose, having dry skin, and feeling constantly cold. This can occur because of an infection, an autoimmune disease, or even after pregnancy. Typically, medications are recommended to help control thyroid hormones to re-balance the levels.
