It's caused by swallowing too much air
(HealthDayNews) -- Belching is caused by swallowing too much air, and there are steps you can take to prevent it.
Penn State University suggests these remedies:
- Remind yourself to eat and drink more slowly.
- Avoid chewing gum, gas-producing foods and drinks, and other triggers.
- Use controlled breathing to deal with anxiety and hyperventilation.
A teaspoon of baking soda diluted in water can relieve the pain associated with not being able to belch. Or you can lie on your side or in a knee-chest position until the gas passes.
