Last night, I ate spicy crayfish and drank beer with friends. Today, I started experiencing diarrhea. Why does drinking beer at night cause diarrhea the next day?

Diarrhea occurring the day after drinking beer may result from intense irritation of the gastrointestinal tract. When a large amount of alcohol enters the gastrointestinal system, it not only irritates the gastric mucosa but also impairs gastrointestinal function. Additionally, consuming large quantities of cold beer continuously stimulates the stomach, accelerating gastrointestinal motility and ultimately triggering diarrhea.
