“I’m having occasional diarrhea, sometimes with blood. I occasionally have mild abdominal pain. I feel run down lately and have lost a few pounds.”
John Jensen is a 32-year-old man who presents to the clinic with a 3-month history of intermittent episodes of diarrhea. He states that he has been having one to two loose bowel movements a day over this time. This is different from his typical bowel pattern. Over the past 4 weeks, he has also noticed blood in some of his stools. The episodes of diarrhea are frequently accompanied by brief periods of mild abdominal pain. These symptoms have caused significant problems with his job, as he is a sales representative for a pharmaceutical company and spends a lot of time driving to appointments. He reports a 5-lb unintentional weight loss over this time period that he attributes to “not having a great appetite and not wanting to make his abdominal pain worse.” He has tried OTC naproxen for the abdominal pain and Pepto-Bismol for the diarrhea, both of which have provided little relief. He does not recall any exposure to sick contacts. He reports no recent international travel. His PCP referred him to a gastroenterologist.
