A 48-year-old man developed abdominal pain and vomiting twelve hours after esophagogastroduodenoscopy. He had lost 4.4 kg while being treated for a gluteal muscle abscess two months prior, and then underwent surgery for gastric perforation one month prior to admission. His-postoperative course was uneventful and endoscopy showed a healed benign gastric ulcer. His-past medical history included schizophrenia and poorly controlled type 1 diabetes. Prescribed medications included insulin and vonoprazan.
