Why Does Diarrhea Burn? (The Painful Science)

Why Does Diarrhea Burn? (The Painful Science) This clip explains the sharp, stinging feeling that often comes with diarrhea and looks at what the body is doing when it happens. It starts with ordinary digestion: after eating, the stomach and small intestine work to take in nutrients, and a typical bowel movement is easy and painless. With diarrhea, the intestines move too quickly, so water is not absorbed properly. That fast movement, together with acidic digestive enzymes, repeated irritation, and spicy meals, can make sensitive skin feel raw and uncomfortable. The video traces the process from normal digestion to the point where the burning starts and closes with the effect of spicy food. 00:00 - The Stinging Mystery 00:20 - How Normal Digestion Works 00:45 - What Goes Wrong During Diarrhea 01:10 - Why The Burning Sensation Happens 01:35 - The Role of Spicy Foods & Final Takeaway
