Dr. G breaks down how to prioritize diabetic foot consults at 1:30 a.m., focusing on recognizing life‑threatening vs limb‑threatening problems. Learn the red flags of systemic infection—fever, tachycardia, hypotension, altered mental status, and tachypnea—and why early recognition matters.

This episode explains key labs and imaging (lactate, procalcitonin, CBC, CRP, ESR, blood cultures, x‑ray/MRI), how to suspect osteomyelitis and critical limb ischemia, and when to call surgery or vascular teams.

Practical takeaways: prioritize sepsis and necrotizing infections first, trend markers like lactate and procalcitonin, and act quickly—time is tissue, tissue is limb, limb is life.
