Charlie Berger, a 58-year-old obese man, comes to a nurse practitioner because he has difficulty swallowing, heartburn, and occasional regurgitation. Answering his nurse practitioner’s questions, Mr. Berger says that his symptoms worsen when he drinks coffee or alcohol.
Endoscopy reveals inflammation in his lower esophagus and poor closure of the lower esophageal sphincter. There is no evidence of esophageal narrowing or movement of the proximal stomach into the thorax.
The nurse practitioner diagnoses gastroesophageal reflux disease (GERD) and tells Mr. Berger to do the following:
Take proton-pump inhibitor drugs to reduce gastric acid.
Elevate the head of his bed.
Avoid eating large meals, especially near bedtime.
Enter a weight-loss program.
Reduce his use of caffeine and alcohol.
