What should you know about diabetes and dry skin?

When blood glucose is persistently elevated, the body may lose more fluid through urine, which can leave the skin feeling dry. Diabetes can also affect nerves and circulation, particularly in the feet and lower legs, changing sensation and the skin’s ability to cope with small injuries. Itching may therefore occur with or without visible scaling.

Dryness is not specific to diabetes. Asteatotic Eczema, Atopic Dermatitis, Psoriasis, frequent hot showers, harsh cleansers, dry air, and some medicines can produce similar symptoms. Cracks between toes or around the heels deserve careful attention because unnoticed breaks can become infected.

Use a short lukewarm shower, a fragrance-free gentle cleanser, and pat the skin dry rather than rubbing. Apply a thick moisturiser soon after bathing and repeat it to rough areas. Emollient Therapy can support the barrier; avoid putting cream between the toes unless a clinician advises it, because trapped moisture can encourage problems there.

Inspect feet and other less-visible areas regularly, especially if sensation is reduced. Keep nails trimmed safely, avoid scratching, and discuss glucose management with the clinician overseeing your diabetes. Moisturiser helps the surface but does not replace diabetes care.

Arrange review for persistent itch, widespread rash, painful cracks, new swelling, warmth, drainage, blisters, or an area that is not healing. Seek urgent advice for rapidly spreading redness, severe pain, fever, or a foot wound, particularly when feeling is reduced.

A clinician can decide whether the skin needs treatment for eczema, psoriasis, infection, or another cause and can check whether medicines or glucose changes are contributing.

Does my skin look like simple dryness, or is there eczema, psoriasis, infection, or another rash? Could reduced sensation or circulation be involved? Which moisturiser and cleanser suit me? How should I protect cracks and check my feet? Do my current medicines or glucose readings need review?
