This could be caused by liver damage. Alcohol is metabolized in the liver; therefore, chronic and excessive alcohol consumption can overload the liver and cause hepatic injury, leading to impaired liver function. As a result, insufficient bile is secreted, compromising fat digestion and potentially causing indigestion and diarrhea.
