Zinc Deficiency Associated with Hypothyroidism: An Overlooked Cause of Severe Alopecia
نویسندگان
چکیده
Hypothyroidism is a common and well recognized cause of diffuse hair loss. Zinc and other trace elements such as copper and selenium are required for the synthesis of thyroid hormones, and deficiency of these can result in hypothyroidism. Conversely, thyroid hormones are essential for the absorption of zinc, and hence hypothyroidism can result in acquired zinc deficiency. The hair loss attributed to hypothyroidism may not improve with thyroxine unless zinc supplements are added, as demonstrated in our case.
