I have this excessive belching problem that I have not been able to get a diagnosis for. I belch when I eat and don't eat. I belch before I go to bed and as soon as I sit up to get out of bed in the morning. I have had numerous tests and medications for indigestion and gastro problems. This has been so depressing to be burping excessively. The worst part is that I am limited to certain activities because of it. When I go for a walk, a very short walk, (like a half block) I get this pressure build up in my chest that feels like a heart attack. The pressure gets so intense that I have to stop walking for a minute or two. Then I belch and belch which relieves the pressure and I am able to continue my walk. I have also had cardio work ups. You name it I have had the test. Nothing has helped. This condition is very strange and frustrating to deal with. No one thing triggers it more than others. I went to an allergist but nothing significant was found there either. I am now watching my diet. For the past two weeks I have cut gluten from my diet because I heard it can cause numerouse health problems. Is there anything else that can be done. I will try anything at this point.
