AccessMedicine's Case of the Week: Gastroenterology: Acute Diarrhea

From: Graber and Wilbur’s Family Medicine Examination and Board Review, 4th Edition: Case 7.09
AccessMedicine's Case of the Week: Gastroenterology: Acute Diarrhea


A 22-year-old previously healthy male reports a 3-day history of explosive and watery diarrhea. He is having up to 6 bowel movements per day. He recalls eating at a new Mexican restaurant 5 days ago. His head sinks a little low as he recalls drinking a "fish bowl"-sized margarita … or at least he thinks he remembers drinking it! He denies fever, blood in his stool, or recent travel. Multiple people ate the same food but he is the only one who is sick. His vital signs are normal (including supine and standing blood pressures), and the remainder of the physical examination is remarkable only for mild, diffuse abdominal tenderness.
