Welcome to the next chapter of Diabetic Foot Files.

👟✨ We’ve teamed up with DARCO to bring you 25% off the POGO shoe! Want to stay active, reduce pressure, and help prevent ulcers before they begin? Visit darcodirect.com/product/pogo/ and use our exclusive code FootFiles25 at checkout to save 25% off your pair.

Welcome to the Diabetic Foot Files Podcast and the LIMBWatch series — where diabetic foot surveillance, wound intelligence, prevention science, and limb preservation come together. I’m Dr. G / Dr. WoundPicasso aka Dr. Gabrielle Hutcheson Donaldson, podiatrist and wound care specialist, and I’m here to educate, empower, and guide you through the evolving world of diabetic foot care.

From wound healing and pressure injuries to surveillance systems and amputation prevention, we break down the science, challenge the myths, and share strategies that help save limbs and improve lives. Whether you’re a patient, caregiver, clinician, or healthcare professional, this is your destination for diabetic foot education, prevention, and preservation.

So let’s dive in — because when you take care of your feet, they take care of you.

Latest Episodes:

Fascia: The Silent Highway of Foot Infections Apr 12, 2026

Show notes

This episode explores the fascia — the continuous connective tissue network beneath the skin — and explains how it can guide healing or rapidly transmit infection in the diabetic foot.

Learn the key anatomy (superficial, deep, and plantar fascia), how diabetes alters fascia through glycation, warning signs of dangerous infections like necrotizing fasciitis, and surgical importance for drainage and debridement.

Prevention tips include glycemic control, pressure offloading, early infection treatment, and mobility/stretching to maintain fascia health.

Diabetic Foot Files: The Hidden Math Behind Every Ulcer Apr 11, 2026

Show notes

Dr. G breaks down the epidemiology of diabetic foot disease, explaining who is affected, where it occurs, and why. He highlights key global figures — over 500 million people with diabetes and up to 25% developing a foot ulcer — to show this is a widespread, preventable problem.

Important facts: ulcers frequently recur (up to 40% within one year), most amputations (about 85%) are preceded by a foot ulcer, and outcomes vary widely by healthcare access and region.

Prevention is possible with routine foot screening, patient education, proper footwear, glycemic control, early treatment, and multidisciplinary care; future tools like AI and wearable sensors aim to shift care from reactive to predictive.

Spring Foot Risks: Beat Blisters Before They Become Amputations Apr 09, 2026

Show notes

Dr. G explains why Limb Loss Awareness Month matters and why spring increases diabetic foot risks. Increased activity, moisture, and seasonal changes create a perfect storm for blisters, fungal and bacterial infections (like Staph and Pseudomonas), and delayed healing. Learn daily foot checks, proper footwear, moisture control, and when to seek podiatric care to prevent ulcers and amputations.

Under Pressure: How Hyperbaric Oxygen Can Save Diabetic Limbs Apr 08, 2026

Show notes

Dr. G explores hyperbaric oxygen therapy (HBOT) for diabetic foot care — how breathing 100% oxygen under increased pressure boosts tissue oxygenation, promotes angiogenesis, improves immune function, and helps heal chronic, non-healing ulcers.

The episode covers HBOT mechanics, indications (especially Wagner grade 3+ wounds and osteomyelitis), typical treatment protocols, benefits in reducing major amputations, limitations, risks, and why HBOT is an adjunct to vascular care, infection control, offloading, and glycemic management.

Invisible Fire: How Free Radicals Destroy the Diabetic Foot Apr 07, 2026

Show notes

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 Apr 06, 2026

Show notes

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 Apr 05, 2026

Show notes

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 Apr 04, 2026

Show notes

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 Apr 04, 2026

Show notes

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.

Tetanus in Diabetic Feet: The Hidden Nail Threat Apr 04, 2026

Show notes

Dr. G explains how tetanus, caused by Clostridium tetani, can enter through small wounds—especially diabetic foot ulcers—and cause jaw stiffness, severe muscle spasms, respiratory failure, and death if untreated.

This episode covers pathophysiology, classic symptoms, incubation time, treatment (wound care, tetanus immune globulin, vaccine, antibiotics, and supportive care), and prevention: regular foot checks, wound hygiene, and staying up to date on tetanus boosters.
