10 Skin Changes That May Indicate Diabetes

Diabetes often develops silently, with many people unaware they have the condition until a routine checkup or noticeable symptoms appear. However, your skin can provide early warning signs of high blood sugar. Here are ten common skin changes that may suggest diabetes or prediabetes.

1. Acanthosis Nigricans – Dark, velvety patches on the neck, armpits, or groin; often linked to prediabetes.
   
   

2. Necrobiosis Lipoidica – Pimple-like bumps that turn into reddish-yellow hard patches, usually itchy or painful.
   
   

3. Digital Sclerosis – Thick, waxy skin on fingers or toes causing stiffness, which may spread to arms or neck.
   
   

4. Diabetic Bullae – Painless blisters on hands or feet resembling burn blisters.
   
   

5. Slow-Healing Wounds – Cuts or sores, especially on feet, that take longer to heal due to poor circulation.
   
   

6. Diabetic Dermopathy (Shin Spots) – Brownish spots or lines, mainly on shins, often confused with age spots.
   
   

7. Eruptive Xanthomatosis – Small reddish-yellow itchy bumps, commonly on buttocks or elbows.
   
   

8. Dry, Itchy Skin – Poor circulation from high blood sugar can lead to persistent dryness.
   
   

9. Xanthelasma – Yellowish patches near the eyelids caused by excess fat and high blood sugar.
   
   

10. Skin Tags – Small, harmless flaps of skin often linked to insulin resistance.
    
    

If you notice these skin changes, consult a doctor and get your blood sugar tested. Managing diabetes with proper diet, exercise, and medical care can help resolve many of these conditions.
