What is belching?
Belching is the act of expelling air from the stomach through the mouth. It usually occurs when the stomach distends (expands) due to too much swallowed air, with the belching releasing the air to reduce the distention.
Other names for belching include burping and eructation.
What Causes Belching?
Belching occurs when the stomach fills with swallowed air. There are a number of reasons why more air than normal may be swallowed, but the most common are:
- Eating or drinking too quickly
- Drinking carbonated drinks anxiety
Babies and young children may swallow large amounts of air without realizing it. This is why babies are burped shortly after drinking breast milk or formula—to expel the excess air that was swallowed during feeding.
It is possible to belch when the stomach is not full of air. This is usually because belching has become a habit or a tool to try to reduce abdominal discomfort. While belching will only relieve discomfort associated with swallowing air, it is not uncommon for people to attempt to relieve other abdominal discomforts in the same way.
It is related to farting.
