Now he reports that he has symptoms daily and also has difficulty sleeping as night due to pain in his epigastric region. His weight at his last appointment 6 months ago was 180 pounds, and his weight today is 160 pounds. He denies dieting, but does report early satiety associated with the stomach pain that worsens when he eats. Additionally, he often feels like he gets food stuck in his throat when he swallows. He has tried Tums and Mylanta for his symptoms without consistent or long term symptom relief. After your physical exam, what is the best course of action for this patient?
