MSFinals-2303

John is a 44-year-old man who presented to you a month ago with a 6-week history of upper abdominal pain, heartburn, and occasional reflux. His medical history is unremarkable, and you both agreed on a plan for a 1-month trial of omeprazole 20 mg daily.

John returns for a follow-up appointment after completing the course of omeprazole. Unfortunately, his symptoms have only slightly improved and are still causing him distress.

What would be the most suitable course of action to manage John’s persistent symptoms?
