The nurse is preparing education to present to a community group on gastroesophageal reflux disease (GERD). Which of the following interventions should the nurse include for patients to help alleviate their discomfort? Select all that apply.

Gastroesophageal reflux disease (GERD) results from the reflux of gastric contents into the esophagus due to a weakened or incompetent lower esophageal sphincter (LES). Patient education focuses on lifestyle modifications that reduce LES pressure, decrease gastric volume, and minimize reflux episodes. Sitting upright for at least one hour after eating dinner uses gravity to keep gastric contents in the stomach, preventing reflux. Avoiding large meals is recommended because large volumes of food distend the stomach, increasing intragastric pressure and the likelihood of reflux. Weight reduction is important because excess abdominal adiposity increases intra-abdominal pressure, which forces gastric contents upward; even modest weight loss can significantly reduce symptoms. Elevating the head of the bed by 6 to 8 inches allows gravity to help prevent nighttime reflux when the patient is supine, reducing nocturnal symptoms and esophageal acid exposure. Eating meals with a very hot beverage is not a recommended intervention and has no evidence supporting benefit for GERD; hot beverages may actually irritate the esophageal mucosa and worsen symptoms. Additionally, patients with GERD are generally advised to avoid caffeinated or carbonated beverages, which can relax the LES. Therefore, the four interventions that should be included in community education are sitting upright after meals, avoiding large meals, weight reduction, and elevating the head of the bed.
