Diabetes: 12 warning signs that appear on your skin

7. Shin spots

Diabetic dermopathy, or shin spots, are common in people who have diabetes

This skin condition causes spots (and sometimes lines) that create a barely noticeable depression in the skin. It’s common in people who have diabetes. The medical name is diabetic dermopathy. It usually forms on the shins. In rare cases, you’ll see it on the arms, thighs, trunk, or other areas of the body.

The spots are often brown and cause no symptoms. For these reasons, many people mistake them for age spots. Unlike age spots, these spots and lines usually start to fade after 18 to 24 months. Diabetic dermopathy can also stay on the skin indefinitely.

Take action

  • Tell your doctor about these spots.
  • Work with your doctor to better control your diabetes.
  • If you haven’t been diagnosed with diabetes, get tested.
