Treating mild hypothyroidism: Benefits still uncertain

More than 10 million adults in the US have hypothyroidism — when the thyroid gland fails to produce enough thyroid hormone to meet the body’s needs — but the vast majority of these cases are considered mild. Whether or not to treat mild hypothyroidism is an ongoing debate. There is a possible link between mild hypothyroidism and coronary artery disease, but researchers found that treating it in older people did not provide any benefit.
