The evolutionary purpose of diabetic neuropathy & Why Our Alarm System Fails in the Modern World and How The Healthcare System becomes that External Warning System for the Patient

This episode explores why pain evolved as a critical protective alarm and how diabetes—through chronic high glucose, inflammation, and microvascular damage—silences that alarm by injuring peripheral nerves. It explains the biological pathways behind diabetic neuropathy, why the feet are especially vulnerable, how repetitive pressure and biofilm-forming bacteria turn painless injuries into ulcers, and the stepwise cascade from nerve damage to amputation. The episode emphasizes prevention and the clinician’s role as an external warning system: early screening, offloading, proper footwear, glucose control, vascular assessment and coordinated limb-salvage care to protect patients’ feet.
