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:

Zombie Cells in the Wound: How Senescent Fibroblasts Sabotage Diabetic Ulcers May 09, 2026

Show notes

Dr. G examines how normal fibroblasts drive tissue repair and how, in diabetic foot ulcers, they can become senescent “zombie” cells that stop dividing, secrete inflammatory SASP factors, and degrade the wound environment.

The episode covers triggers (hyperglycemia, oxidative stress, ischemia, infection), clinical signs and biomarkers of senescence, the vicious cycle with biofilm, and emerging approaches—including senolytics, targeted dressings, and debridement—to reduce senescent burden and improve healing.

Diabetic Foot Village: A Plan to Prevent Amputations May 08, 2026

Show notes

This episode proposes the "Diabetic Foot Village" — a coordinated multi-sector surveillance and response model that shifts care from late-stage hospital interventions to early prevention and continuous monitoring.

The framework connects a clinical core team, footwear and rehab supports, surveillance technology, and trained community touchpoints (nail techs, pharmacists, caregivers) with a national risk registry, rapid referral pathways, and home monitoring to catch problems earlier.

Goals include reducing preventable amputations, lowering costs, improving limb salvage and equity in underserved areas — inspired by a patient story that highlights why shared, community-driven detection matters.

Limb Watch: Every Wound Has A Clock May 08, 2026

Show notes

In this episode Dr. G introduces Limb Watch, a simple framework to recognize early warning signs of diabetic foot disease before they become emergencies. She explains why small changes—warmth, redness, odor, swelling, drainage, pain changes or glucose instability—matter, and how a universal alert system (green, yellow, orange, red) can prompt faster intervention and prevent amputations.

Limb Watch is designed for everyone—patients, caregivers, nurses, podiatrists, nail technicians and communities—and calls for better education, surveillance, and shared accountability to preserve limbs through earlier recognition and timely action.

From Tuberculosis to Toes: Building a System That Stops Amputations May 07, 2026

Show notes

This episode compares tuberculosis control strategies to diabetic foot ulcer care, showing how a public-health system transformed TB from a deadly epidemic into a controllable disease and how similar systems can prevent avoidable amputations in people with diabetes.

Dr. G explains key parallels—latent progression, unequal burden, and the need for engineered compliance—and proposes practical lessons: standardized screening, mandatory referral pathways, remote monitoring, multidisciplinary teams, and a national diabetic foot surveillance system to catch problems early and reduce preventable limb loss.

The Magic Words in Woundcare- Words That Save Limbs: The Hidden Language of Diabetic Wound Care May 07, 2026

Show notes

This episode examines how medical language shapes urgency, triage, and outcomes in diabetic wound care. It explains key terms—like limb-threatening infection, critical limb ischemia, osteomyelitis, necrotizing soft tissue infection, deep space abscess, and systemic signs—that trigger faster interventions and can be the difference between healing and amputation.

Dr. G explores the psychology of terminology, the dangers of minimizing wounds, and the balance between creating appropriate urgency and avoiding alarmism. The episode emphasizes precise documentation and the phrase "time-sensitive limb salvage" as a tool to mobilize teams and save limbs.

THE GEOGRAPHY OF AMPUTATION” Why Your Chances of Keeping a Leg Depend on Where You’re Born May 07, 2026

Show notes

In this episode Dr. G explores how where a person lives can determine whether a diabetic foot ulcer heals or leads to amputation. Using real-world examples, he explains how limited access to podiatry, vascular care, wound supplies, and prevention programs in low-income regions turns preventable wounds into life-threatening problems.

The episode outlines the economics and history behind these disparities, the human cost of amputation, and practical solutions—screening, community care, affordable offloading, and multidisciplinary teams—that can save limbs and lives.

H2 Therapy: Could Hydrogen Help Save Diabetic Feet? May 06, 2026

Show notes

In this episode Dr. G explores molecular hydrogen (H2) — the smallest molecule with surprising biological effects — and how its selective antioxidant and anti-inflammatory actions might improve wound healing in diabetic foot ulcers.

We review the mechanisms, delivery methods, preclinical and emerging clinical evidence, and practical limits: H2 shows promise as an adjunctive redox modulator but is not a replacement for standard care like debridement, offloading, infection control, and vascular assessment.

Hidden in the Waves: Vibrio, Pseudomonas and the Dangers of Water to Diabetic Ulcers Apr 26, 2026

Show notes

This episode explains how common water sources — oceans, lakes, rivers, pools, hot tubs and aquariums — can introduce dangerous microbes into diabetic foot wounds, including Vibrio, Aeromonas, Pseudomonas, Mycobacterium, Candida and molds.

Dr. G describes why diabetic wounds are especially vulnerable (poor circulation, neuropathy, impaired immunity), the warning signs of severe infection, and how some organisms can cause rapidly progressive necrosis or chronic non‑healing ulcers.

Practical takeaways: avoid water exposure with open wounds, tell your clinician about any water contact, seek prompt evaluation for concerning symptoms, and tailor cultures and antibiotics to possible waterborne pathogens.

Amputated Spirit: The Hidden Loss of Integrity in Diabetic Limb Care Apr 25, 2026

Show notes

Dr. G explores how diabetic limb salvage is not only about preventing physical amputation but also about protecting the clinician’s and patient’s integrity and will to fight. He warns that system delays, corner-cutting, burnout, and patient despair can cause an invisible — and often irreversible — "amputated spirit."

The episode urges early action, relentless advocacy, clear patient education, and documentation to preserve outcomes and the human spirit behind care. It’s a call to choose what’s right over what’s easy in diabetic foot medicine.

Masked Threats: Microvascular Collapse, Gait Compensation, and Silent Biofilms Apr 24, 2026

Show notes

Dr. G investigates a diabetic foot ulcer that appears routine but reveals multiple hidden causes: microvascular ischemia, compensatory gait mechanics, biofilm infection, immune suppression, static pressure from prolonged standing, and medication-induced hemoconcentration. The episode emphasizes that diabetic foot ulcers are rarely due to a single factor and highlights the need for comprehensive evaluation beyond obvious signs.
