I have had severe diarrhea and vomiting of bile for 40 years. it only happens sporatically, 5 months to 1 year apart. the last time It finally got so bad my blood pressure dropped to 60/40 (dehydration) I could not see with my eyes open everything went black I did not pass out I could still hear people talking and I could talk. I had my gallbladder out 2 1/2 years ago thought that was the problem. when I went to the E.R. about 6 months ago they found I had diverticulosis, gastritous, and acid reflux, by using the scope. I followed up with my G.I. doctor who told me non of what they found is causing my problem. I tested neg for siliacs desease. I am on pantopropazal for acid reflux. I have just had another episode, I cant go on like this. the only thing I can guess is I had dairy based deserts for thanks giving. could dairy products be causing this?
