Nighttime Oxygen Debt: How Sleep Apnea Halts Wound Repair

Nighttime Oxygen Debt: How Sleep Apnea Halts Wound Repair

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.
