There is no single medication that provides a permanent cure for chronic acidity, but it can be successfully managed. For medical treatment, doctors commonly prescribe Proton Pump Inhibitors (PPIs) like Omeprazole or H2 blockers like Famotidine for short-term healing. For long-term relief, lifestyle changes are essential: avoid trigger foods (spicy, fatty, caffeinated), eat smaller portions, do not lie down for three hours after meals, and manage weight. If symptoms persist, consult a gastroenterologist to investigate underlying causes like H. pylori infection or a hiatal hernia, which may require targeted treatment or corrective surgery.
