Why Is My Skin Always Itchy? It Could Be Diabetes!

Diabetes can affect every part of the body, including your skin.

If your skin constantly feels itchy even though there’s no rash or bumps, don’t be too quick to blame allergies. For people with diabetes, chronic itching (pruritus) is a common symptom. Studies show that about 30% of people with diabetes experience skin problems, including persistent itching.

Why Does Diabetes Cause Itchy Skin?

High blood sugar levels over time can damage small blood vessels and nerves, resulting in reduced blood flow to the skin. Poor circulation leads to dry, irritated skin. And if you keep scratching, it can break the skin and open the door to infections.

People with diabetes also tend to have a weakened immune system, which increases their risk of infections, especially fungal infections such as Candida albicans. This type of yeast thrives in warm, moist areas, such as the underarms, groin, under the breasts, and between the fingers or toes. The result? Unbearable itching.

Sometimes, itchiness can also be a side effect of diabetes medications or insulin. If you notice redness, bumps, or itching around injection sites, it’s best to consult your doctor right away.

What Can You Do?

• Use mild, fragrance-free soaps and avoid hot showers.
• Gently pat your skin dry after bathing—don’t rub it.
• Apply moisturizer immediately while your skin is still slightly damp.
• For arid areas like heels or elbows, choose moisturizers with 10–25% urea.
