About 5 months ago I started regurgitating some of the food I ate. I was undergoing a little more stress than usual so I attributed it to that. It also was infrequent, happening maybe once a day. Over time it has gotten progressively worse to where I'm regurgitating everything I eat or drink. Here is what happens: I eat or drink a normal amount and then about 10-15 minutes after I eat, I regurgitate a mouthful of whatever I just consumed. I spit that out and a minute later, another mouthful. This can continue for over an hour. I've been in the situation where I have no other option than to reswallow the food but when I do that I get a bad stomach ache and it will try to come back up later. The longer I hold it in, the more acid it gets. This is truely awful to deal with and I've done the barium swallow and upper endoscopy with negative results. I don't eat as much because I know what will happen. Any other options? Any answers? Whats wrong with me? Please help.
