Dr. Gabby (Dr. G) the Skin Gardener reframes wound care as "skin gardening," explaining how skin regenerates layer by layer and why diabetic foot ulcers reflect a breakdown of the body’s ecosystem. She covers history, skin anatomy and cell roles, how diabetes disrupts healing (neuropathy, ischemia, infection), and why the basement membrane, fibroblasts, and perfusion are essential.

Practical takeaways include the core needs for growth: oxygen and perfusion, offloading and mechanical protection, moisture balance, debridement, and replacing missing signals. She also previews future tools—stem cells, bioengineered skin, and personalized therapies—to cultivate better healing outcomes.

Dr. G traces William Harvey's discovery of blood circulation and shows how it transformed medicine and modern wound care.

The episode explains why movement, pressure, and vascular health are essential for healing diabetic foot ulcers and outlines clinical approaches—revascularization, exercise, offloading, and glycemic control—that restore circulation and save limbs.

This episode explains bone scans as functional, nuclear medicine tests that reveal bone metabolism—blood flow, inflammation, infection, and repair—often before structural imaging shows changes.

Learn the three phases (flow, blood pool, delayed), how osteomyelitis typically lights up all phases, pitfalls like Charcot foot and ischemia, and advanced options (SPECT‑CT, labeled white blood cell scans, PET) that improve diagnosis and guide limb‑salvage decisions.
