Sweet and fried foods delay digestion and relax the lower oesophageal sphincter, causing acid reflux. Drinking water dilutes the acid temporarily, but doesn't prevent this trigger. Diet Plan: Avoid fried, fatty, and highly sugary foods. Eat smaller, more frequent meals, and avoid lying down for at least 2-3 hours after eating. Medication: For quick relief, you can use over-the-counter antacids (like calcium carbonate). For ongoing symptoms, a daily H2 blocker (like Famotidine) or a Proton Pump Inhibitor (like Omeprazole 20mg) taken 30 minutes before your first meal can help. Please consult a doctor in person for a proper prescription and to rule out other issues.
