The initial step in treating gastroesophageal reflux disease (GERD) typically involves medications that suppress stomach acid and comprehensive lifestyle modifications. Medical treatments such as proton pump inhibitors (PPIs) reduce stomach acid production, thereby supporting the healing of the esophageal lining. In addition to medication, adjustments to lifestyle and dietary habits are critically important for the effectiveness of the treatment. For instance, obesity can exacerbate reflux symptoms by increasing intra-abdominal pressure. In this regard, patients are advised to achieve their ideal weight, quit smoking, avoid tight clothing, and stay away from trigger foods like fatty foods, fried dishes, tomato paste, alcohol, chocolate, mint, onions, garlic, and coffee. In cases unresponsive to medical and lifestyle treatments, or for those with specific indications, surgical intervention is considered an effective and commonly performed treatment option.
