Dry skin of the feet and legs is a common finding for patients coming to the podiatry office. There are many reasons for dry skin to occur, from hereditary skin conditions to toxic chemical exposure to infections. Some causes of dry skin are more than skin deep. Dry skin can be the sign of an underlying medical condition. Two of the more common ones are thyroid conditions and diabetes. Both of these can result in serious skin issues including severe dryness. In patients with dry skin that are not responding to topical moisturizers, internal causes may need to be considered. Medical work up to rule out thyroid conditions and diabetes is a good starting point. Allergy testing may also be needed. Controlling underlying medical conditions can go a long way on improving skin conditions. Nutritional support is also important.
