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:

To Kling or To Kerlex, that is the question- Mastering Gauze Rolls in Diabetic Foot Ulcer Care Oct 01, 2025

Show notes

Dr. G explains the key differences between Kling (conforming) and Kerlex (bulky padding), when to use each, and how wrapping technique and tension can affect perfusion and healing in diabetic feet.

Includes practical application steps, pressure checks to avoid ischemia, tips for moisture and allergy management, and clinical pearls for better wound outcomes and patient education.

Sparks of Healing: How Piezoelectricity Could Transform Diabetic Foot Care Sep 30, 2025

Show notes

This episode explains the piezoelectric effect—how mechanical stress creates tiny electrical signals—and how those signals guide cell migration, angiogenesis, collagen deposition, and epithelialization in wound healing.

It describes how diabetes weakens natural bioelectrical cues through neuropathy, poor circulation, and collagen changes, and reviews clinical approaches that restore or mimic these signals: electrical stimulation, low‑intensity ultrasound, and emerging piezoelectric dressings and wearables.

The episode also covers practical limitations (cost, compliance, lack of standard protocols) and highlights future directions like nanotech dressings, piezoelectric insoles, and AI‑guided devices that could make step‑powered healing a valuable adjunct in limb salvage.

IV or Oral? Choosing the Right Antibiotic for Diabetic Foot Infections Sep 23, 2025

Show notes

Dr. G explains when to use IV versus oral antibiotics for diabetic foot infections, covering severity-based choices, common empirical regimens, and why wound cultures matter.

The episode reviews pharmacokinetics, expected timelines for improvement (48–72 hours), typical durations for soft-tissue infection and osteomyelitis, and criteria to step down from IV to oral therapy.

It also highlights monitoring, common side effects and drug interactions, red flags for treatment failure, and the importance of a multidisciplinary approach to optimize outcomes.

Understanding Drop Foot: A Hidden Diabetic Danger Sep 22, 2025

Show notes

Dr. G explains drop foot — the inability to lift the front of the foot — and why people with diabetes are at special risk due to neuropathy, compression, and poor circulation.

This episode covers how to recognize drop foot, key diagnostic steps (EMG, imaging, vascular testing), urgent red flags, and a step-by-step treatment plan including AFOs, FES, physical therapy, surgical options, wound care, and vascular referral for ulcers.

Global PAD Association with Emmy Award winning journalist, entrepreneur and advocate Kym McNicholas -Saving Limbs, Saving Lives: Inside the Fight Against PAD with Kim Nicholas Sep 16, 2025

Show notes

Dr. G interviews Emmy winning journalist Kym Nicholas, CEO and co‑founder of the Global PAD Association, about peripheral arterial disease (PAD), its strong link to diabetes, common misdiagnoses, and why early vascular evaluation can prevent unnecessary amputations.

They discuss patient stories, systemic gaps in care, lifestyle interventions like supervised walking programs, global best practices, and resources to get help at padhelp.org.

Second Chances: Repurposed Drugs Healing Diabetic Foot Ulcers Sep 15, 2025

Show notes

In this episode of Diabetic Foot Files, Dr. G explores how existing medications — from metformin and insulin to statins, fentanyl, sildenafil, doxycycline and nitric oxide donors — are being repurposed to help heal stubborn diabetic foot ulcers. We review the biology behind each drug, early clinical evidence, and why topical formulations may offer targeted benefits with minimal systemic exposure.

Listeners will learn which agents show the strongest signals (topical insulin, topical metformin, topical statins), which remain promising but mixed (topical phenytoin), and how repurposed therapies fit as adjuncts to standard wound care rather than replacements. Practical takeaways include safety considerations, off-label use discussions, and the need for larger trials.

Semaglutide Steps In: New Hope for PAD Patients Sep 15, 2025

Show notes

This episode explores new randomized evidence that semaglutide, a GLP-1 receptor agonist used for diabetes and weight loss, can improve walking distance and quality of life for people with type 2 diabetes and symptomatic peripheral arterial disease (PAD).

The landmark STRID trial showed median gains of about 26 meters (mean ~40 m) in walking distance over a year, along with better pain scores and daily function. Large real-world studies also suggest fewer PAD-related hospitalizations and amputations.

Benefits likely come from multiple effects: weight loss and improved glucose control, anti-inflammatory actions, better endothelial function and muscle metabolism, all combining to improve perfusion and exercise capacity.

Semaglutide is an adjunct to standard PAD care (exercise, smoking cessation, statins, antiplatelets, revascularization when needed). Common side effects include GI symptoms; monitor eye health, pancreatitis risk, and avoid use in patients with MEN2 or medullary thyroid cancer history.

The Dangerous Duo: PAD and Kidney Disease in Diabetes Sep 13, 2025

Show notes

In this episode of Diabetic Food Files we explain how peripheral arterial disease (PAD) and chronic kidney disease (CKD) interact in people with diabetes to worsen circulation, slow wound healing, and raise the risk of infection and limb loss.

We outline the key symptoms to watch for, recommended screening tests (ABI/toe–brachial index, urine albumin-to-creatinine ratio, eGFR), and why every person with diabetes should be evaluated for both conditions.

Management strategies discussed include antiplatelet and lipid therapy, ACEi/ARBs, SGLT2/GLP-1 agents, supervised exercise, diligent foot care, revascularization when needed, and close coordination among nephrology, vascular, podiatry, and endocrinology.

Early detection, aggressive risk control, and a multidisciplinary care team can greatly reduce the chance of amputation and preserve kidney function—know the signs and get screened.

From Hippocrates to Gene Therapy: The Journey of Diabetic Peripheral Arterial Disease Sep 12, 2025

Show notes

This episode of Diabetic Foot Files explores peripheral arterial disease (PAD) in people with diabetes — its history, how diabetes accelerates arterial damage, the biology behind impaired wound healing, and clinical clues to distinguish ischemic from neuropathic ulcers.

We cover bedside tests (ABI, TBI, TcPO2), modern revascularization options, medical and lifestyle management, and emerging therapies, emphasizing early recognition and multidisciplinary care to improve limb salvage and outcomes.

How Nicotine Silences Healing: The Diabetic Foot Risk Sep 11, 2025

Show notes

Dr. G explains how nicotine — from cigarettes, vapes, pouches, and nicotine replacement products — reduces blood flow, disrupts immune and cellular repair, and slows or worsens healing in diabetic foot wounds.

He summarizes the science, lists nicotine-containing products, and gives practical, evidence-based guidance for clinicians and patients on screening, cessation options, and wound-care strategies to improve outcomes while working toward nicotine abstinence.
