I used to be a GI nurse and I worked with a specialists. I am also very sorry that you had a bad experience with your c-scope. Most of the time patients say that the prep the night before was worse than the actual scope! Everyone is different though and it is an uncomfortable procedure. Just making an appointment @ a GI office is enough to make you uncomfortable! Please don't let this experience keep you from doing it again. If they took any biopsies, in about a week the results will be back. If you had any polyps, it is VERY important to have this test done again anywhere from 1-5 yrs. (depending on type of polyp). Choose another GI Doc next time or schedule an appointment (or @ your follow up appt.) to tell you Doc how uncomfortable you were and maybe next time he'll know how your body responds to the meds better. I would personally think it would be easier to stick with the same Dr. because you won't be as nervous next time and with your records etc... If any doctor called me "fat," and did'nt adjust my meds because of that, I think I would take my business somewhere else. Hope everything goes well.
