I had a capsule endoscopy a few weeks ago and just got the results leading to my tentative diagnosis with Crohn's. The test itself is very easy, but the prep work is the not so great part...here's an account of my experience, as what I read on the internet didn't give any detail of what to expect. The day before, I had to stop eating and stuck to a liquid diet (broth, water, apple juice...) and then the perscription "clean-me-out" drink was said to begin at 5PM. From my experience with colonoscopy prep, I decided to start earlier than 5 because for some reason it doesn't hit me until about 6-7hrs later (does anyone else have this problem?). You are to have nothing to drink after 10PM that night, except sips to take pills. The morning of my test I couldn't eat/drink anything. When I go to the hospital, the nurse took me into an office, not even a patient room, and had me hold up my shirt while she put 7 electrodes on my belly (each with adhesive pathes about 3''x2''). She then connected all of the electrodes long thick wires to a very large receiver - this was the most surprising moment, the size of the receiver (about 9''x6''x4'') and then put the receiver into this fanny-pack carrier. I then sat down to swallow the camera, which is slightly larger than a vitamin sup or fish oil pill. The nurse then instructed me to drink a glass of water followed by this mixture that "is given to newborns to decrease tummy bubbles" - it was actually quite yummy! I was then sent home and instructed to do the following: don't eat for 4hrs, then you can have a small snack (I had some soup and crackers), and return in 8hrs to have the patches removed (which also removed quite a bit of my skin, but I'm weird like that). You'll also have to look at the receiver every so often to make sure this light is flashing (indicating the camera and receiver are "talking"). I laid down most of the day because the receiver was heavy and hurthing my back...I'm not going to do well as a pregnant woman

And then the camera eventually passes about 24-48hrs later (well, it's supposed to, but reading this thread it sometimes does not - see your doctor) and it's flushed! Which I also thought was neat! The results for mine took about 2weeks since there are so many photos to look at. I would advise you to bring a large coat/sweatshirt to wear after everything is attahced - I felt like a patient trying to escape with half my life support equipment as I left the hospital. Hope that helps!!!!
