Dr. G explores hyperbaric oxygen therapy (HBOT) for diabetic foot care — how breathing 100% oxygen under increased pressure boosts tissue oxygenation, promotes angiogenesis, improves immune function, and helps heal chronic, non-healing ulcers.

The episode covers HBOT mechanics, indications (especially Wagner grade 3+ wounds and osteomyelitis), typical treatment protocols, benefits in reducing major amputations, limitations, risks, and why HBOT is an adjunct to vascular care, infection control, offloading, and glycemic management.
