I recently spent four days in the hospital due an unexplained GI bleed. I lost two and a half pints of blood and the bleed stopped on its own after a couple days. They scoped my pouch and went as far up as they could, but could't find anything except "old" blood left over from the bleed. They're guessing that I was probably bleeding somewhere between my stomach and pouch, where they couldn't get to with the scope. The Dr. mentioned using a camera pill to get a look at everything. My concern is that I'm prone to to blockages and this worries me. The Dr. said they use a wax pill they can "track" first. If it does get stuck, it will eventually melt and pass and I obviously won't be a good candidate. I was just curious if anyone has used the camera pill and can tell me what to expect or how it worked. Byn the way, I also had an upper GI and an MRI, but neither showed anything.
