Can diabetes cause skin ulcers?

Diabetes may lead to skin ulcers. Prolonged hyperglycemia damages microvessels and peripheral nerves throughout the body, impairing the skin’s capacity for repair and defense. Even minor skin injuries may fail to heal properly, progressively worsening into ulceration and infection. Persistent non-healing wounds or expanding ulcerated areas require prompt medical evaluation and treatment.

Abnormal blood glucose levels disrupt systemic microcirculation, resulting in chronically inadequate blood supply and oxygenation to the skin. This impairs subcutaneous nutrient delivery. Concurrently, diminished peripheral nerve sensation delays recognition of abrasions or friction injuries, allowing damage to progress unchecked. Moreover, a hyperglycemic environment promotes bacterial proliferation; even superficial epidermal breaks may gradually deepen, leading to recurrent, non-healing ulcers.

Early wound management is essential for diabetic skin ulcers. This includes timely debridement of necrotic tissue and adjunctive antimicrobial therapy to control local inflammation. Maintaining stable glycemic control is the cornerstone for halting ulcer progression. Consistent, evidence-based glucose management—combined with appropriate wound care—supports gradual regeneration of healthy tissue and progressive wound healing.

Maintain overall skin cleanliness and integrity; avoid trauma, bumps, or abrasions—particularly on the limbs. Adopt a light, regular diet to stabilize metabolic function and reduce the risk of skin ulceration.
