We present the case of a 54-year-old man with severe acute diarrhea during alcohol withdrawal, despite special feeding, correction of vitamin deficiencies, and protection of the gastrointestinal mucosa. Diarrhea is often overlooked, so we aim to draw attention to the risk of combined malnutrition, acute diarrhea, and alcohol withdrawal because this can lead to lethal complications. We recommend that patient's bowel movements should be carefully observed during alcohol withdrawal, even during hospitalization.
