Diabetic Foot Files: The Hidden Math Behind Every Ulcer
04/11/2026 | 9 mins.
Dr. G breaks down the epidemiology of diabetic foot disease, explaining who is affected, where it occurs, and why. He highlights key global figures — over 500 million people with diabetes and up to 25% developing a foot ulcer — to show this is a widespread, preventable problem.

Important facts: ulcers frequently recur (up to 40% within one year), most amputations (about 85%) are preceded by a foot ulcer, and outcomes vary widely by healthcare access and region.

Prevention is possible with routine foot screening, patient education, proper footwear, glycemic control, early treatment, and multidisciplinary care; future tools like AI and wearable sensors aim to shift care from reactive to predictive.
Spring Foot Risks: Beat Blisters Before They Become Amputations
04/10/2026 | 17 mins.
Dr. G explains why Limb Loss Awareness Month matters and why spring increases diabetic foot risks. Increased activity, moisture, and seasonal changes create a perfect storm for blisters, fungal and bacterial infections (like Staph and Pseudomonas), and delayed healing. Learn daily foot checks, proper footwear, moisture control, and when to seek podiatric care to prevent ulcers and amputations.
Under Pressure: How Hyperbaric Oxygen Can Save Diabetic Limbs
04/09/2026 | 21 mins.
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.
Invisible Fire: How Free Radicals Destroy the Diabetic Foot
04/08/2026 | 22 mins.
This episode explains how free radicals (ROS and RNS) drive tissue damage and delayed healing in diabetic foot ulcers, covering their sources, detection, and effects on cells, blood flow, nerves, and infection.

It also reviews the body’s antioxidant defenses and clinical strategies—glycemic control, debridement, advanced dressings, hyperbaric and topical oxygen, and antioxidant therapies—to reduce oxidative stress and promote healing.
Nighttime Oxygen Debt: How Sleep Apnea Halts Wound Repair
04/06/2026 | 20 mins.
This episode explains how obstructive sleep apnea (OSA) can cause repeated nighttime oxygen drops that impair wound healing in people with diabetic foot ulcers, creating chronic inflammation, poor collagen formation, and stalled repair.

Dr. G reviews the science linking intermittent hypoxia to delayed healing, how CPAP restores nighttime oxygen and may improve glycemic control and tissue repair, and why clinicians should consider screening for sleep apnea as part of holistic wound care.
