A 27-year-old female presented with 6 months of upper abdominal pain and occasional nausea and vomiting. On examination, she was found to be severely malnourished with a body mass index of 14.06. Laboratory tests found iron deficiency anemia. The cause of her weight loss and anemia was unclear, though inflammatory bowel disease such as Crohn's disease or ulcerative colitis were suspected given her abdominal pain and elevated inflammatory markers. Further diagnostic testing was needed to determine the underlying cause.
