9. Red or skin-colored raised bumps
Whether this skin condition is associated with diabetes is controversial. We know that most people who have granuloma annulare do not have diabetes. Several studies, however, have found this skin condition in patients who have diabetes. One such study found that people with diabetes were most likely to have granuloma annulare over large areas of skin and that the bumps came and went. Another study concluded that people who have granuloma annulare that comes and goes should be tested for diabetes.

If you have diabetes, you’re more likely to have dry skin. High blood sugar (glucose) can cause this. If you have a skin infection or poor circulation, these could also contribute to dry, itchy skin.
