This episode traces coffee’s journey and asks whether daily caffeine affects diabetic foot ulcer healing.

It summarizes the science on how caffeine influences blood vessels, sleep, blood sugar, inflammation, fibroblasts, and hydration, and explains that moderate, unsweetened coffee is unlikely to severely impair healing while excessive intake, sugary drinks, poor sleep, or circulation issues can hinder recovery.

Practical advice is given: consult your doctor or nutritionist, prioritize overall wound care (circulation, glycemic control, nutrition, sleep, hydration), and consider alternatives like green or herbal teas when appropriate.
