Diabetic Foot Files

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 medication adjustments.

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, avoid eyes/mucous membranes, and have trained clinicians administer high‑dose patches).

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%, fasting glucose 100–125 mg/dL, 2‑hour OGTT 140–199 mg/dL), why different tests can identify different people, who should be tested, and which clinicians to involve (PCP, endocrinologist, dietitian, diabetes prevention programs).

The episode emphasizes prevention: lifestyle-based diabetes prevention programs can reduce progression, metformin is not automatic, and early action can change your metabolic trajectory — protecting overall health and reducing future foot and limb complications.

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 protect the remaining limb and restore mobility.
