Your thyroid produces a hormone that regulates body temperature, metabolism, and heartbeat. When that hormone production becomes disturbed (and what causes that disturbance can vary from person to person), your body may experience many symptoms—or none at all.
“Many adults can have thyroid disease without having any symptoms at all,” says Wendy Sacks, M.D., endocrinologist in the Division of Endocrinology, Diabetes and Metabolism and the Thyroid Cancer Program at Cedars-Sinai in Los Angeles. But very often, people will have varying signs that their thyroid is not operating optimally. Whether or not you have a collection of symptoms or just one or two, it’s important to discuss them with your doctor. “I tell my patients that every patient with thyroid disease has his or her own constellation of symptoms,” Dr. Mitchell says.
