E08.621

Clinical Causes: Underlying conditions such as chronic kidney disease, pancreatic disorders, or autoimmune diseases leading to diabetes mellitus. Prolonged high blood sugar levels causing nerve damage (diabetic neuropathy). Poor blood circulation due to vascular disease, increasing the risk of foot ulcers. Inadequate foot care or injury, especially in individuals with sensory loss or decreased sensation. Delayed diagnosis or management of diabetes, leading to complications.

Key Symptoms: Open sore or wound on the foot that is slow to heal. Redness, swelling, or warmth around the ulcer. Pain or tenderness in the affected foot, though sometimes numbness reduces pain sensation. Discoloration or blistering near the ulcer area. Signs of infection such as pus, foul odor, or increased swelling. Unusual foot appearance, including deformities or calluses that may contribute to ulcer formation. General symptoms of diabetes, including fatigue, increased thirst, and frequent urination.

Diagnosis Path: Visual inspection of the foot to assess the ulcer's size, depth, and signs of infection. Blood tests to evaluate blood glucose levels and identify the underlying cause of diabetes. Imaging tests such as X-rays to detect bone involvement or signs of underlying infection. Vascular studies to assess blood flow to the legs and feet. Sensory tests to evaluate nerve damage or peripheral neuropathy.

Treatment Protocols: Controlling blood glucose levels through medication, diet, and lifestyle changes. Proper wound care, including cleaning, dressing, and infection control measures. Debridement of the ulcer to remove dead tissue and promote healing. Promotion of blood flow through vascular management or surgical intervention if necessary. Use of antibiotics if infection is present. Offloading pressure from the ulcer using special footwear or devices. Addressing underlying health issues, such as kidney or vascular problems. Regular monitoring and follow-up to prevent recurrence and complications.
