Question: A 49-year-old Caucasian woman presents with complaints of fatigue and dysphagia for 3 months and nausea, abdominal pain, and diarrhea for 3 weeks. Her dysphagia is mostly to solids and not accompanied with odynophagia. Her abdominal pain is located in the epigastric area and “feels like a deep ache.” Her diarrhea is watery, occurring 5–6 times per day, occasionally with fecal urgency. She could not identify factors that would make her symptoms worse or better. She denies fever or chills, bloating, cramps or tenesmus, and states no overt gastrointestinal (GI) bleeding.
