It is normal to feel gassy after eating or drinking something that is high in carbohydrates, proteins, or fats. You may also feel this way if you are consuming large amounts of air while you eat or drink. To help reduce the feeling of being gassy, try to eat smaller meals, chew food slowly, avoid carbonated drinks, and practice mindful eating. Additionally, you can try over-the-counter medications like antacids to help reduce discomfort.
