Warning signs on your skin: 7 symptoms that may indicate uncontrolled diabetes

Diabetes doesn’t just affect blood sugar levels—it can also show visible signs on the skin. When blood glucose remains high for long periods, it impacts circulation, immunity and nerve health, often leading to noticeable skin changes.

Recognising these early warning signs can help in timely diagnosis and better management. Here are seven skin symptoms that may signal uncontrolled diabetes.

1. Dark Patches on Skin (Acanthosis Nigricans)

One of the most common signs of insulin resistance, acanthosis nigricans appears as dark, thick, velvety patches on the neck, underarms, groin or knuckles. These patches may feel slightly raised and are often an early indicator of uncontrolled blood sugar.

2. Extremely Dry and Itchy Skin

High blood sugar causes frequent urination, which can lead to dehydration. As a result, the skin becomes dry, flaky and itchy. Poor circulation can worsen the problem, especially on the lower legs and feet.

3. Frequent Skin Infections

People with uncontrolled diabetes are more prone to bacterial and fungal infections. Recurrent boils, styes, fungal rashes, and yeast infections may signal weakened immunity due to elevated glucose levels.

4. Slow-Healing Wounds and Cuts

If minor cuts, bruises or wounds take a long time to heal, it could be a sign of diabetes. High blood sugar damages blood vessels and nerves, reducing blood flow and delaying the healing process.

5. Yellowish Bumps on the Skin (Xanthomatosis)

Sudden appearance of small, yellowish bumps surrounded by red skin—often on the arms, thighs or buttocks—can indicate high triglyceride levels linked to uncontrolled diabetes.

6. Skin Tags

Skin tags are small, soft growths that often appear on the neck, eyelids, or underarms. While generally harmless, multiple skin tags can be associated with insulin resistance and diabetes.

7. Tingling, Burning or Numb Sensation

Uncontrolled diabetes can cause nerve damage, leading to tingling, burning or numbness in the skin, especially in the hands and feet. These sensations often worsen at night.
