My question concern the gastrointestinal system. First let me give you a little back ground I had stomach tumor removed in Mar or 2007. Everyone thought it was cancer so I went to MD Anderson and they too throught it was cancer, To make a long story short they said it was not cancer but they have no idea what the tumor maybe to this day. They had to remove the whole bottom half of my stomach to remove the tumor that went all the way around it with a whole in the middle. I have also had my gallbladder removed. My problems are I vomite around 1-2 hours after I eat. Sometime when I feel this way I also feel like I am going to have diarhea then after vomiting the diarhea feeling goes away also, it also works in reverse too at times I feel like I am going to have diarhea and then I have diarhea and the vomiting feeling goes away. Also when I vomite I never vomite much just about 2-4oz and I am not losing weight. I have many egds and colonostipies and nothing has turned up other than some minor irratation in my stomach. I have been battling this for years even before my stomach surgery and have yet to find an answer. THanks Stephen
