Why do you get diarrhea every time drink beer?

Beer does not cause diarrhea. In fact, beer is sometimes used as a home remedy for diarrhea. There are a few possible reasons why you may be experiencing diarrhea after drinking beer, including:

- Intolerance to gluten, barley, or hops. Beer is made from barley, which contains gluten. If you are intolerant to gluten, you may experience digestive symptoms, including diarrhea, after drinking beer. Hops can also cause digestive issues in some people.

- Overindulgence in alcohol. Drinking too much alcohol can cause dehydration, which can lead to diarrhea.

- Food poisoning. If you consume contaminated food or water along with beer, you may develop food poisoning, which can cause diarrhea.

- A bacterial or viral infection. Diarrhea can be caused by bacteria or viruses, which can be present in food or water.
