The experts are not all in agreement on this one. According to dermatologists, more than 20% of people with diabetes struggle with dry skin and other skin conditions like rashes and skin tags. Many believe the dry skin is due to hyperglycemia, meaning the high glucose levels in your blood are causing your skin to dry out. Others believe there may be something already in the skin of people prone to diabetes that also causes dry skin. The research is still out. Suffice to say: if you have diabetes and dry skin, you need help, look no further!
