This document discusses diabetic foot disease, including its pathophysiology, clinical manifestations, management, and prevention. It notes that diabetic foot disease is caused by neuropathy, ischemia, and infection leading to tissue breakdown. The pathophysiology involves both metabolic neuropathy and neuroischemia. Clinical manifestations depend on whether the foot is primarily neuropathic or ischemic. Management involves debridement, wound dressing, antibiotic therapy, metabolic control, and potentially vascular interventions or amputation. Prevention emphasizes good foot care, inspection, and control of diabetes and related conditions.
