Diabetic Foot Ulcer

A diabetic foot ulcer is an open sore or wound that occurs on the foot of a person with diabetes mellitus, most often on the sole or another pressure-bearing area. It develops from a combination of peripheral neuropathy, which reduces sensation and allows unnoticed injury, and peripheral arterial disease, which impairs blood flow and slows healing. Diabetic foot ulcers are a leading cause of lower-limb amputation and carry a substantial risk of infection. Management focuses on wound debridement, pressure offloading, infection control and improving blood supply, alongside strict blood glucose control.
