This is a problem with your thyroid. That's a hormone-producing gland in your neck. The thyroid makes hormones that help control many activities in your body. These hormones affect things like your metabolism and heart rate. With hypothyroidism, your thyroid does not make enough hormones to meet your body's needs.
Hypothyroidism is most often caused by an autoimmune disorder called "Hashimoto's disease." It can also result from medications, radiation therapy, thyroid surgery and from other, less common causes.
There are many symptoms of hypothyroidism. They vary from person to person. You may have fatigue, weakness and body aches. You may gain weight, and your face may look puffy. Hypothyroidism can cause dry skin and dry, thinning hair. You may have constipation. You may have depression. Women may have heavier-than-normal menstrual periods, and trouble getting pregnant. Ask your doctor for a full list of symptoms.
Hypothyroidism is treated with a synthetic thyroid hormone pill. You take it every day. It normalizes your hormone levels. Your healthcare provider will create a plan that's right for you.
