Hi..., Avoid foods and drinks that trigger heartburn. Everyone has specific triggers. Common triggers such as fatty or fried foods, tomato sauce, alcohol, chocolate, mint, garlic, onion, and caffeine may make heartburn worse. Avoid foods you know will trigger your heartburn. Eat smaller meals. Avoid overeating by eating smaller meals. Don't lie down after a meal. .. Increase your fiber intake. Adding fiber to your diet increases the weight of your stool and speeds its passage through your intestines. Slowly begin to eat more fresh fruits and vegetables each day. Choose whole-grain breads and cereals... Exercise most days of the week. Physical activity increases muscle activity in your intestines.
