Dr. G explores how religious fasting can affect people with diabetes and diabetic foot ulcers, explaining the physiology (glucose, ketones, hydration), the risks to wound healing and infection, and the difference between safe fasting and medical emergencies like DKA or severe dehydration. Practical advice emphasizes talking with your primary care doctor, endocrinologist, and wound care team before...

In this episode Dr. G explains how the phrase "path of least resistance" applies to diabetic foot infections and why a small surface ulcer can hide extensive, limb‑threatening disease. He reviews surgical principles (incision, drainage, debridement), vascular assessment, multidisciplinary limb salvage strategies, and the importance of timely follow‑up, offloading and patient engagement. Early reco...

This episode explains toe pulp (felon) infections and why a tiny wound at the tip of the toe can become a serious problem, especially in people with diabetes and neuropathy. It covers causes (puncture wounds, ingrown nails), anatomy, signs to watch for, imaging, the importance of vascular assessment and source control, and why offloading and timely care matter.

Dr. G explores the idea that wounds carry bioelectrical signals that guide cell movement and repair, and that diabetes can disrupt these electrical instructions in diabetic foot ulcers. The episode reviews how researchers measure wound electrical fields, how hyperglycemia may impair them, and whether targeted electrical stimulation could restore polarity and improve healing, with implications for...

Dr. G explores the potential of autologous fat grafting for diabetic foot ulcers, explaining how adipose-derived cells may aid angiogenesis, modulate inflammation, and restore soft-tissue padding to improve healing and reduce recurrence.

Episode Summary Where Are Your Shoes? Turning Family Conversations Into Diabetic Foot Surveillance | LIMBWatch with Jonathan Brocklehurst In this episode of LIMBWatch, Dr. Gabrielle Hutcheson Donaldson sits down with Jonathan Brocklehurst MSc, MIRL, MRCPod, HCPC Registered Podiatrist, wound-care specialist, educator, and author of Grandpa, Where Are Your Shoes? for a powerful conversation about on...

In this episode Dr. G explains pinch grafting — a simple autologous technique that places tiny pieces of a patient’s own skin onto a prepared wound bed to create epithelial “islands” that promote closure. She covers the history of the Reverden graft, the biology of graft take (plasmatic imbibition, inosculation and neovascularization), and how epidermal islands accelerate r...

This episode of Diabetic Foot Files shares ten practical habits to prevent serious foot problems and limb loss in people with diabetes. The host emphasizes vascular assessment as the top priority and walks through daily foot checks, never ignoring small wounds, checking shoes, wearing proper footwear, protecting feet from heat, avoiding home surgery and soaking, taking toenails seriously, knowing...

Dr. G explains how type 2 diabetes can develop quietly and describes common but often overlooked early signs — persistent thirst and urination, fatigue, blurry vision, recurrent infections, slow-healing cuts, numbness in the feet, increased hunger, and unexplained weight loss. The episode also covers how diabetes is diagnosed (A1C, fasting glucose, and glucose tolerance tests), who should be teste...

Dr. G uses the giraffe-in-quicksand metaphor to show how clinical inertia and tunnel vision quietly worsen diabetic foot ulcers. Clinical inertia isn't doing nothing—it’s doing too little: repeating dressings, documenting instead of investigating, or delaying referrals. She outlines four types of inertia (diagnostic, therapeutic, referral, cognitive), stresses multidisciplinary care, a...

In this episode Dr. G explains how medical necessity and insurance rules affect diabetic foot care, limb salvage, and amputation prevention. You’ll learn what "medically necessary" really means, how prior authorization and denials work, what to include in an appeal or medical necessity letter, and the clinical consequences of delays. The episode also highlights health equity—how socioeconomic barr...

This episode explains what a PICC line is (Peripherally Inserted Central Catheter), how it delivers prolonged antibiotics, and why it is not automatically required for every diabetic foot infection. Dr. G covers when a PICC makes sense, the importance of source control and multidisciplinary care, the risks and warning signs to watch for, and how patient involvement and infectious disease guidance...

Dr. G discusses pyomyositis — a deep skeletal muscle infection that can occur in people with diabetes, how it differs from cellulitis, its stages, common causes, typical pathogens, diagnostic steps including MRI and labs, and the importance of source control, imaging, and vascular assessment. Key takeaways: the visible ulcer may be only the surface of a deeper infection, early recognition and imag...

Dr. G explains pyroptosis — an inflammatory form of programmed cell death driven by inflammasomes, caspase‑1, and gasdermin D — and how its pore‑forming, cytokine‑releasing shutdown can amplify inflammation. The episode explores how pyroptosis affects keratinocytes, fibroblasts, and macrophages in diabetic foot ulcers, potentially preventing healing by keeping danger signaling active, and why bala...

This episode explains what NPO (nil per os) means, why clinicians use it to reduce aspiration risk during anesthesia or procedures, and why it’s more complex for people with diabetes. Key points include glucose monitoring every 2–4 hours, tailored insulin and medication plans, risks from gastroparesis, and the importance of asking the care team specific questions about allowed intake and medicatio...

Dr. G introduces Peculiar Podiatry with a deep dive into the "purple toe"—a visual clue that can mean anything from a simple bruise to dangerous arterial or venous problems, infection, or neuropathy, especially in people with diabetes. This episode explains how to evaluate timing, pain, pulses, position changes, and when urgent vascular or emergency care is needed.

Dr. G explores how capsaicin, the active compound in chili peppers, can reduce burning neuropathic pain by overactivating and desensitizing pain-sensing nerves. The episode explains that capsaicin is not a cure for diabetic neuropathy or a treatment for ulcers, notes differences between low‑dose creams and the 8% prescription patch, and highlights safety precautions (apply only to intact skin, avo...

Prediabtes isn’t “ Almost Diabetes” . This episode explains how type 2 diabetes often begins years before diagnosis as prediabetes — a compensatory metabolic state where insulin resistance, pancreatic stress, liver overproduction of glucose, and visceral fat-driven inflammation quietly disrupt glucose control. You’ll learn the diagnostic thresholds (A1c 5.7–6.4%...

This episode explains what "stump shrinkage" really means—residual limb volume changes, edema, tissue remodeling, and how different amputation levels affect function and prosthetic fitting. It outlines practical management steps: compression and dressing strategies, wound and vascular monitoring, prosthetic planning, physical therapy, and the extra vigilance required for people with diabetes to pr...

This episode explores why some diabetic foot ulcers remain inflamed yet fail to clear microbes, distinguishing contamination, colonization, local infection, and clinical infection. It explains how immune dysregulation, neutrophil extracellular traps (NETs), macrophage dysfunction, biofilm, ischemia, hypoxia, neuropathy, and necrotic tissue create an ecosystem that prevents healing. The episode emp...
