My aeromedical examiner said ibswithout any tests then sent me to a general prac who said ibs try fiber supp. after no improvment probably because i didn't take it regularly and didn't know about trigger foods then sent me to a gi who did all the blood work, and other bio samples found no disease, blood where it's not supposed to be said it's ibs, no need for further tests do to age, health, history etc after the worst attack ever almost passing out and dialing 911 after an hour of extreme pain i took matters into my own hands and searched and found heather's books. i informed my gi that we would be doing some more tests just to be sure. we are following it up with more tests tomorrow followed by an abdom cat in two weeks. So yes i have had 3 diagnosis' but not all of the tests. my gi claims that there is no way do to my symptoms ie stomach pains, blood (there aren't any)etc that it must be ibs. sounds alot like chapter 2.
