Why Do We Burp?

Why Do We Burp?

We all burp. But why does it happen?

In some cultures, burping after a meal is a sign of respect.

It’s a fact of life: We all burp. But why is burping a thing?

We burp for a couple different reasons, and they all have to do with gas buildup in the stomach. When we’re drinking soda, we swallow a lot of carbon dioxide. The gas we swallow needs to come back up, so it does. Also, the bacteria in our stomach create gases including methane, which also needs to come back up. If these gasses pass through the stomach and into the intestinal tract, well, they’ll come out the other end instead.

It’s been estimated that over the course of a day, we release about a quart of gas. While in some cultures it’s considered impolite to burp in public, in others it’s considered a sign of respect after enjoying a good meal. So eruct away, friends!
