Invisible Fire: How Free Radicals Destroy the Diabetic Foot
04/08/2026 | 22 mins.
This episode explains how free radicals (ROS and RNS) drive tissue damage and delayed healing in diabetic foot ulcers, covering their sources, detection, and effects on cells, blood flow, nerves, and infection.

It also reviews the body’s antioxidant defenses and clinical strategies—glycemic control, debridement, advanced dressings, hyperbaric and topical oxygen, and antioxidant therapies—to reduce oxidative stress and promote healing.
Nighttime Oxygen Debt: How Sleep Apnea Halts Wound Repair
04/06/2026 | 20 mins.
This episode explains how obstructive sleep apnea (OSA) can cause repeated nighttime oxygen drops that impair wound healing in people with diabetic foot ulcers, creating chronic inflammation, poor collagen formation, and stalled repair.

Dr. G reviews the science linking intermittent hypoxia to delayed healing, how CPAP restores nighttime oxygen and may improve glycemic control and tissue repair, and why clinicians should consider screening for sleep apnea as part of holistic wound care.
The Ultimate Cinematic Wound:The Crucifixion Decoded: Medical Science Behind the Cross
04/06/2026 | 17 mins.
In this episode of Diabetes with Dr G. Dr. G analyzes the crucifixion from a clinical and historical perspective, breaking down biomechanics, respiratory failure, wound mechanics, infection risks, and the role of nails and foot trauma.

Dr. G connects the topic to diabetes and podiatry—how chronic illness would affect outcomes—and highlights clinical takeaways about positional asphyxia, systemic effects of wounds, and the importance of offloading and wound care.
The Medicine of the Crucifixion: Hematohidrosis, Scourging, and Asphyxiation
04/04/2026 | 11 mins.
Dr. D examines the wounds of Jesus Christ through a medical lens, covering hematohidrosis in the garden, the scourging and crown of thorns, and the biomechanics of crucifixion that led to systemic collapse.

This concise episode connects historical trauma with clinical lessons about perfusion, infection risk, and how wounds reveal the limits of the human body—framed within Easter reflection.
Silent Bone Death: Avascular Necrosis in the Diabetic Foot
04/04/2026 | 14 mins.
This episode explains avascular necrosis (osteonecrosis) — bone death from loss of blood supply — and why it’s particularly dangerous in people with diabetes. Dr. G reviews common causes, high-risk foot sites (talus, navicular, metatarsal heads), and how diabetic microvascular disease and neuropathy increase limb risk.

Key points covered include signs and how AVN differs from Charcot foot, the role of MRI for early diagnosis, staging, non‑surgical and surgical treatment options, and prevention strategies such as glycemic control, early imaging, offloading, and cautious steroid use.
