Diabetic Foot Ulcers (DFUs) refers to a condition in which diabetic patients, due to prolonged poor blood sugar control, develop non-healing wounds in any part of the foot. The causes of diabetic foot ulcers include neuropathy, peripheral vascular disease, and in severe cases, it may lead to infection and even the risk of amputation. According to statistics, approximately 1/4 of diabetic patients experience the challenge of "diabetic foot ulcers" at some point in their lifetime.
