diabetic foot ulcer (DFU)

A diabetic foot ulcer (DFU) is a sore or wound that develops on the foot of someone with diabetes, often due to nerve damage (neuropathy) and poor blood flow. Diabetes can reduce sensation, making it easier to injure the foot without noticing. Additionally, impaired blood circulation hampers healing. These ulcers can become deep, infected, and difficult to treat, increasing the risk of serious complications like infections or amputation. Proper foot care, managing blood sugar, and early treatment are essential to prevent and heal DFUs.
