When drinking carbonated drinks, burping is usually due to the gas produced by carbon dioxide gas in the drink in the stomach, which leads to flatulence in the gastrointestinal tract. Here are some ways to reduce or avoid burping when drinking carbonated drinks:

1. Drink slowly: Drink carbonated drinks slowly to release carbon dioxide gas in the stomach for a longer time.

2. Avoid over-inflation: Try to avoid drinking a lot of carbonated drinks, such as carbonated water in carbonated drinks.

3. Stay upright: When drinking carbonated drinks, try to stay upright and avoid lying flat or prone, which will help reduce flatulence in the stomach.

4. Chew while drinking: Chewing carbonated drinks helps to release carbon dioxide gas and reduce flatulence in the stomach.

5. gargle after drinking: after drinking carbonated drinks, gargle helps to reduce carbon dioxide gas in the mouth.

In short, the way to reduce or avoid burping when drinking carbonated drinks is to release carbon dioxide gas in an appropriate way to reduce flatulence in the stomach.
