Diabetes: 12 warning signs that appear on your skin

9. Red or skin-colored raised bumps

Granuloma annulare causes red, pink, or bluish-purple bumps on the skin

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.

Granuloma annulare

This skin condition causes bumps and patches that may be skin-colored, red, pink, or bluish purple.

Take action

  • Let your doctor know if you have bumps like those shown here, especially if the bumps come and go.

10. Extremely, dry itchy skin

If you have diabetes, you’re more likely to have dry skin.

Dry, itchy skin

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.

Take action

  • Tell your doctor about your extremely dry skin. Gaining better control of diabetes can reduce dryness.
  • If you continue to have dry skin after you gain better control of your diabetes, a dermatologist can help.
