Re: Belching all day long
Burping is definitely normal after eating meals. It's not acid, it's gas. As things start churning, gas is created. Too much gas pressure and the gate will open.
However, I still think there are 2 different "burps". Essentially, I've NEVER burped in the classic sense. Never from gas; never had a "loud belch" that forced my mouth open (or could, if you don't control it).
My "burping" is all inside, unknown to the world, doesn't go beyond my throat, and since it's been out of control ever since I suddenly "got GERD", I suspect it is the sphincter failing and transiently blowing open (includes the upper sphincter at the throat, which also "trips" alot). Before I had this bad problem, I called these virtually unnoticeable (i.e., by public) "throat burps". I'd probably have a couple a day. Now it's virtually all the time.
Oh, and they DON'T make me feel better. I often feel worse. The more I "burp", the worse I get. Another reason I suspect it is the LES opening.
