In this episode of Diabetic Foot Files the host exposes why patients with diabetic wounds are often unfairly blamed and explains how system gaps, provider bias, and limited training cause poor outcomes. Learn what thorough wound investigation looks like, what patients can and cannot control, and how both clinicians and patients can advocate for better, evidence-based limb preservation.

Dr. G explains why people with diabetes are far more vulnerable to surgical site infections — covering neuropathy, poor blood flow, high blood sugars, immune dysfunction, and common pathogens that colonize incisions. The episode reviews high-risk foot procedures, signs of infection, and evidence-based prevention: preoperative optimization, vascular assessment, strict glucose control, meticulous su...

In this episode Dr. G explains “holiday heel” — calcaneal (heel) fractures that spike during the holidays from ladder falls, slips and carrying heavy decorations. Learn the common mechanisms, key exam findings (plantar bruising, Mulder’s sign, inability to bear weight), and why diabetics are at higher risk due to neuropathy, poor bone quality, and slower healing. Dr. G covers emergency concerns su...

This episode offers a concise Thanksgiving survival plan for people with diabetes: which foods help or harm wound healing, how to manage blood sugar before and after the meal, and which holiday habits raise ulcer risk. Learn practical tips on protective footwear, offloading during long cooking or shopping days, burn and fall prevention, and when to inspect feet or seek urgent care. Simple, actiona...

Dr. G uses the Mercury Retrograde analogy to explain why diabetic foot ulcers often recur, covering medical and mechanical causes like osteomyelitis, unresolved pressure, neuropathy, scar tissue, and poor footwear. He outlines common hotspot locations, signs of underlying bone infection, and why healed skin remains fragile. The episode emphasizes immediate reassessment for reopened wounds, essenti...

Dr. G compares diabetic foot ulcers to a "situationship"—a pattern of ignoring early warning signs, inconsistent care, and delayed follow-up that lets small wounds become serious. This episode explains how ulcers can appear suddenly, linger, and then worsen if not treated promptly. Dr. G covers the red flags (swelling, drainage, odor, persistent callus), the essentials of assessment and treatment...

Dr. G returns with a real-world diabetic foot case about exposed tendons, focusing on the peroneus brevis. This episode explains why exposed tendons resist healing, when tendon excision is necessary (infection, necrosis, persistent biofilm, or lack of granulation), and the trade-offs between biomechanics and limb salvage. Practical tips covered include keeping exposed tendons moist, immobilization...

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 od...

In this episode Dr. G explains why offloading — removing pressure from the ulcer site — is the single most important intervention for neuropathic plantar diabetic foot ulcers. He reviews evidence and guidelines that favor non-removable total contact casts, practical offloading options, and how to integrate offloading into a full treatment plan. Key points include screening and treating infection a...

Dr. G examines how growth factors act as fertilizers, and how oxygen and light therapies function like sunlight and air to revive chronic diabetic foot ulcers. He explains key molecules (EGF, PDGF, VEGF, FGF, TGF‑β), the problem of growth factor resistance in diabetes, and bedside treatments including PRP, topical/recombinant growth factors, topical and hyperbaric oxygen, and photobiomodulation. U...

Dr. G explores how wound healing is an active metabolic process — what wounds need (calories, protein, oxygen, vitamins and minerals), how hyperglycemia and malnutrition stall repair, and a case where nutritional repletion spurred granulation within 14 days. The episode emphasizes checking nutrition labs, optimizing protein and micronutrients, controlling glucose, and using a multidisciplinary tea...
