Dry skin
Hypothyroidism—which is an underactive thyroid that doesn’t produce enough hormones—can cause dry skin. “Other skin changes can be seen at times, such as decreased sweating and coarse skin. These symptoms all occur when the regulatory hormones produced by the thyroid decrease or disappear,” Matilda Nicholas, MD, PhD, a dermatologist at Duke Health said. Dry skin in patients with hypothyroidism is very common—one study published in the Indian Journal of Dermatology found that a whopping 100 percent of patients with hypothyroidism experienced it.
