Hey all, I just wanted to get some feedback from some fellow ppl who may suffer from similar symptoms. I had an endoscopy and flex sigmoidoscopy on the 18th of June and drs said everything looked normal, that in fact there weren't even any signs of acid erosion anywhere nor any amount of acid sitting there. I was/am totally shocked. Since I was sixteen I've suffered from ulcer-type pain and have taken prilosec to the pt that it helps a little but not always. I've also had IBS symptoms for a while and it looks as though this may be the gastro culprit. Still, i don't have any explanation for the occassional vomiting i have, which occurs in the mornings prior to eating (usually) and consists of only bile. Is there a condition that would cause vomiting of bile if I have not eaten? This seems to be the only time it occurs but the dr said he doesn't know. any helpful info???
