When Metabolism Fails the Foot: Insulin Resistance, Hypertension & Non‑Healing Ulcers
2/01/2026 | 18 mins.
In this episode of Diabetic Foot Files Dr. G traces diabetic foot ulcers upstream to metabolic causes: insulin resistance and chronic hyperinsulinemia drive sodium retention, sympathetic overactivity, RAS activation and endothelial dysfunction that produce microvascular collapse and poor wound healing.

Learn why clean-looking wounds still won’t close, how to target root causes (lifestyle, medications, supplements, and team-based care), and why limb salvage starts with restoring metabolism and vascular health—not just surface treatment.
Iodine Isn't the Enemy: Debunking the Cytotoxic Myth
2/01/2026 | 20 mins.
This episode explains where the belief that iodine is "cytotoxic" came from, contrasting old in vitro lab studies with real-world wound biology. It outlines how povidone‑iodine (a slow‑release formulation) controls infection and biofilm, and why infection can be worse for healing than controlled iodine use.

It also compares iodine to isopropyl alcohol, showing alcohol is more damaging to open wounds, and gives practical takeaways for managing infected or critically colonized diabetic foot ulcers.
Myiasis Explained: How Flies Target Wounds and How to Prevent Infestation
1/30/2026 | 28 mins.
This episode explains myiasis (maggot infestation of wounds): how and why flies lay eggs in wounds, the lifecycle from egg to adult fly, risk factors (especially in diabetes), clinical signs, complications like infection, and urgent management steps.

It also covers prevention strategies, differences between medical (sterile) maggot therapy and wild infestations, and practical advice on when to seek immediate medical care.
When Skin Sends SOS: Understanding the Kennedy Terminal Ulcer
1/28/2026 | 20 mins.
This episode explains the Kennedy terminal ulcer: a sudden, rapidly progressing sacral wound often seen near end of life, and how it overlaps with pressure injury and skin failure concepts.

Dr. G discusses the underlying physiology (perfusion collapse, inflammation, microthrombi), the role diabetes plays in lowering tissue reserve, clinical recognition, management focused on comfort and dignity, and the importance of clear documentation and family communication.
Felt Padding 101: The Low-Tech Offload That Heals Diabetic Foot Ulcers
1/28/2026 | 13 mins.
In this practical episode Dr. G shows how felt padding — an adhesive-backed wool or synthetic material cut to create a pressure "donut" — can redistribute plantar pressure and promote healing of diabetic foot ulcers.

He covers why offloading matters, supplies and step-by-step application, clinical evidence, a real case demonstrating substantial pressure reduction and healing, and common pitfalls with troubleshooting tips.

Key takeaways: felt padding is affordable, customizable and effective when paired with proper footwear and monitoring; replace regularly and watch for skin breakdown or shifting.
