[ELI5] how does drinking alcohol affect digestion?
gpt
You don't absorb anything in your stomach, its a pouch that dissolve things into a liquid that is then absorbed in the intestine.

Intestines absorbs the liquid through many many small capillaries on the surface.

As it turn out, alcohol irritates and inflames your intestine. And in turn reduces the ability for it to absorb nutrients. w/e you cant absorb gets send down as waste. Which is why heavy alcohol drinking leads to digestion issues.
