Some investigations suggest that the excess weight may be slowing down the thyroid, instead of a slow thyroid making it easy to pack on the pounds. Dr. Kitahara presented her findings on obesity, thyroid function and weight at the 86th annual meeting of the American Thyroid Association in Denver Sept. 24.1
