Dr. G returns to Diabetic Foot Files to explain why winter can increase the risk of aggressive diabetic foot infections, including gas gangrene. She reviews how cold-induced vasoconstriction, reduced oxygen, cracked skin, and warm boot environments create anaerobic conditions that favor Clostridium species.

The episode covers warning signs to watch for—severe pain, discoloration, crepitus, foul odor, and systemic toxicity—along with recommended diagnostics (X-ray, CT/MRI, labs) and urgent treatments such as surgical debridement, IV antibiotics, and hyperbaric oxygen.

Practical prevention tips are shared: daily foot checks, moisturize safely, keep footwear dry and rotated, avoid direct heat, maintain circulation, and follow up promptly with your clinician. The message: stay vigilant this winter and seek immediate care for suspicious wounds.
