Diabetes and caring for skin and feet

Diabetes can affect the skin, nerves and circulation, making early recognition of wounds and infection important. Complications are not inevitable: daily care and regular follow-up help reduce risk.

Why skin needs extra attention

High glucose, reduced circulation and neuropathy can contribute to dryness, infection and delayed wound healing. Reduced pain or temperature sensation can allow a foot injury to go unnoticed. Little or no pain is therefore not enough to show that a foot is healthy. [1][2]

A simple daily check

Look at the top and sole of each foot and between the toes, using a mirror or help if needed. Check for cuts, blisters, colour change, swelling or new warmth. Inspect inside shoes before wearing them, choose well-fitting footwear and clean socks, and avoid walking barefoot. [1]

Dryness and itch

Wash gently with lukewarm water, pat dry and use a fragrance-free moisturizer on dry areas. Moisturize the tops and soles of the feet while avoiding cream between the toes. Avoid hot water and abrasive sponges. Persistent itch or itch with a rash needs assessment because dryness is not its only cause. [1][2]

Fungal infection and other skin changes

Dry between the toes after washing or ablution, and do not pick cracked skin. Fungal infections may need specific treatment, and affected nails may also need assessment. Ring-shaped or yellowish leg patches and changes at injection sites have several possible causes and should be examined rather than self-diagnosed. [2]

When urgent assessment is needed

Arrange prompt medical assessment for a new foot wound, ulcer, redness, swelling or warmth, even without pain. Fever, redness, blackened skin or rapid deterioration needs urgent care. Do not open blisters, cut corns or use acid corn-removers yourself, especially when sensation is reduced. [1]

Follow-up and preventing recurrence

Close follow up for blood sugar and blood pressure are important . If using insulin, review injection technique and site rotation and avoid injecting into lumpy or damaged areas. Prevention depends on sustainable routines rather than waiting for a serious problem to appear. [1][2]

Key point

Inspect the feet daily, moisturize dry skin while keeping between the toes dry, and do not wait for pain before seeking assessment of a new wound. [1][2]
