Wasn't sure, so I looked it up myself.

Alcohol is a cellular poison. Its initial contact with the lining of the bowel may cause some cellular damage. As the alcohol in the blood is recirculated regularly and bathes the intestinal cells, it creates further damage. Damaged cells mean inadequate digestion, followed by diarrhea.


Is alcohol causing my diarrhea?


It is likely that the diarrhea and gas you are experiencing are effects of the alcohol, and not of any liver disease. Alcohol has toxic effects on the cells of the gastro-intestinal system. It can cause inflammation of the stomach (gastritis) and generalized irritability of the bowelcausing discomfort and diarrhea.

Similarly, alcohol can impair absorption in the small intestine. This means that the waste moves quicker through your bodymaking it difficult for the colon to successfully remove all the water from the material. The result of which is diarrhea. Also, if nutrients are not absorbed in the small intestine, bacteria in the colon can digest extra nutrients and creates gas as a bi-product.
