Gastroesophageal reflux disease (GERD) is common in the elderly. Patients often complain of less severe or frequent heartburn than their younger cohorts, but because of prolonged acid exposure over many years, the elderly have more complicated reflux disease including esophagitis, peptic strictures, and Barrett's esophagus. Potential factors aggravating GERD in the elderly include medications, which reduce lower esophageal sphincter pressure, higher frequency of hiatal hernia, impaired motility, and decreased saliva volume and bicarbonate concentration. Early endoscopy is indicated in all elderly patients with GERD, regardless of symptom severity. The medical and surgical treatment of GERD in the elderly generally follows the same principles as for any adult patient.
