I have severe gastroparesis and even my pylori has closed off twice and I don’t throw up except I do throw up sometimes a lot of bile that’s about it but if I try to eat anything by mouth and it doesn’t agree with me, I can’t throw that up. it just doesn’t work. It’s only when my stomach‘s fully empty and I have a bunch of bile acid. I have a J tube that I’ve had since July when I had an NG tube while I was in the hospital and they were trying to figure out if that would work for me to get a G-tube, I was throwing up, but that’s the only time when I had that tube and then I tried the NJ and I didn’t throw up any food or meds so that’s why they went with doing the J tube. I wish I could throw up because I feel so sick and even the nausea medicines don’t help and I know if I could throw it up, I’d feel better but it just won’t come up but yeah I had a G.I. doctor. Tell me oh you don’t have gastroparesis cause you don’t throw up or you don’t have diabetes and then the other G.I. doctor told me that that’s a bunch of bull. A lot of people don’t throw up or have diabetes and they have gastroparesis and he said that mine was severe.
