I'll start by saying I have never, to my knowledge burped in the sense that most people do, like a loud belch. I try to, but I can't. But I have really tiny "burps" almost like my throat is growling. Its feels like just a very small amount, if any, gas is even being expelled. I feel that if I could burp one good time, it would help these annoying little things go away, but I can't. Lately they have been constant, about one per minute, give or take, unless i'm laying down or reclined slightly. It only occurs when i'm sitting up straight or standing. I have no other medical condidtions related to the digestive system. (no frequent heartburn, ect.) and I dont feel like this is a problem, its just really annoying. Ive heard it might be swallowed air, but I don't chew gum or drink carbonated beverages. I drink 4 bottles of water per day. Could this problem be my diet? Do some people just not burp loudly, so this is what happens because of that? What should I do?Any help would be great. Thanks.
