What could cause excessive burping?

Thought I might try and ask about this here.

Just an annoying problem that’s been happening to me recently: after eating something, no matter what is, I’ll be burping frequently for a long time after. I know I haven’t been eating any differently than usual, but this burping all the time thing is different and has been going on for several days. It was enough that my mom noticed and asked if something was wrong, so I know that it’s atypical. There’s no pain or anything associated with it, it’s more annoying and embarrassing than anything else, but I’m just curious about what may be causing it.

Any help is appreciated :)
