The thyroid is a small gland in the neck that plays a major role in regulating the body’s metabolism. If it produces the wrong amount of hormones – either too much or too little – various systems in the body will not function properly.
With an overactive thyroid, also called hyperthyroidism, you can have problems such as anxiety, sleep trouble, weight loss and irregular heartbeats. With a low thyroid, or hypothyroidism, you can have dry skin, constipation, brittle hair and memory problems, and women can have irregular menstruation.
If you are experiencing any of these symptoms on a daily basis, see your physician. Early treatment of thyroid disease can help people control their symptoms and live normal lives.
