The actual procedure isn't bad. You will be sedated and chances are you won't remember anything. I remember watching some of mine on the monitor but I was heavily sedated enough that I didn't feel anything. The preparation is definitely the worst part. The day before the exam you can only drink clear liquids and you have to take strong laxatives to clean you out so the doctors can get a good look at your colon. I actually tried working from home on the day I prepped but didn't get much work done since most of my time was spent sipping laxative/electrolyte or on the commode. Different doctors prefer different preps. Mine was drinking 4 litres of electrolyte/laxative drink. Some doctors use 2 litres plus pills. I'm definitely going to ask for something different next time because getting the last litre down was torture. (I'm supposed to get them ever 5 years since one of my uncles had colon cancer). Something else I've been hearing about is colonic hydrotherapy for prep. You still have to fast the day before but instead of laxative you have super enemas to clean you out. Most doctors don't like or trust this method but you can ask if they are willing to try it.
My wife had it done and it's quite horrid. The procedure is unpleasant but the actual bad part is the day before!!!!!!!!!! OMG! You are not allowed to eat anything solid for 24 hours. Only very light soup, water and jello while at the same time you have to drink this medicine that will give you extreme diarrhea for 24 hours. They advice that you just make yourself comfortable in the bathroom and just hang out in there for the duration of the medicine. It was torture. You will eventually not poop anything but a clear liquid and that area will get really red and irritated from all the moisture. Then the next night before the procedure you can't eat anything even though you are starving and drive to the doctor or have somebody take you there. They will give you sedation but you will still be semi awake and it may feel uncomfortable but not as horrible.
I read that it involves the use of a colonoscope—a long, thin, flexible instrument connected to a camera and video display monitor. The colonoscope is inserted into the rectum and moved through the entire colon. If the healthcare provider notices anything of concern during your colonoscopy, a biopsy (removing a small amount of tissue to examine) may be performed.
Really does the tissue remove stop the bleeding?
Oh my =O!
