(Concern) Frequent burping

As I get older, digestion also improves.

They say it can't be done.

However, I tend to digest food well.

And it was a loud burp at that.

It suddenly became more frequent.

I don't pay much attention at home.

At a seat with other people outside

I'm really worried about whether I might burp.

I'm trying to do it quietly by covering it with my hand.

I try hard, but if I feel frustrated while being considerate of others' feelings

They also switch seats to do it.

Burping occurs because a lot of air enters the stomach.

They say that the habit of chewing slowly is beneficial.

I've been chewing for a long time, and something has changed.

I have nothing but my age, but I couldn't find any medication either.

It's a truly absurd concern.

Is there a good way to reduce burping?
