Chief Complaint

“My belly hurts, and I can’t stand the sight of food.”


Charles Porter is a 58-year-old man who presents to the Family Practice Center with a 2-day history of nausea, vomiting, and epigastric and RUQ abdominal pain. The patient states that the pain began several hours after eating a large platter of cheese ravioli with sausage and meatballs at a local restaurant. The pain intensified and was associated with escalating nausea followed by several episodes of vomiting. The vomiting finally ceased but the abdominal pain has persisted and is made worse after meals. The pain is now dull, constant, and “bores” to his back. Lying up in bed or sitting in a chair seems to relieve some of the pain. Since the initial episode, his appetite has decreased and he has been avoiding fried or fatty foods. He denies any change in stool color or consistency.
