Consume soft foods like rice, curd, bananas, and cooked vegetables at regular, short meals. Steer clear of late-night meals, tea and coffee, alcohol, smoking, and spicy or oily foods. Incorporate probiotics, drink enough water, and avoid lying down right away after eating.

For acidity, medicines like antacids (like pantoprazole) can help. Along with medicines, avoid spicy or fatty foods, eat smaller meals, and do not lie down immediately after eating. Always follow your doctor's advice, especially for long-term use.
