Have had colonoscopies twice.
Very similar to the descriptions by
@zand above.
The bowel prep drinks taken beforehand were actually more bother than the procedure, itself. Reiterate be close to toilet the bowel prep liquid is similar to pouring water down a twisted hosepipe. The flow through is immediate gushing with some residual trickling for a while after.
The staff carrying out the procedure were very respectful, and dignity was preserved. They issued a gown and some pants with a flap at the back, so that the only part of anatomy exposed was the ‘access point’.
On both occasions I was offered sedation, and ‘ gas and air’ (entonox) . As my fear of being sedated is greater than fear of pain, I chose neither. Just concentrated on breathing, gently, and watching the progress on screen. (I did feel it a shame that my most attractive feature is not on open view.
). There was a bit of pressure discomfort in my abdomen, as the probe moved around corners, but it really wasn’t bad. I have had more discomfort from a stubbed toe. If you feel you would prefer the sedation, do have it. I have been told that it just makes you feel relaxed, and you can sleep it off, before being discharged.
The most recent colonoscopy was last year. The doctor told me , before I left the treatment room, that my bowel was healthy. I didn’t need to stay in the recovery area for very long, due to not having sedation. I was given the best cup of coffee I had ever had, even though it was cheap instant coffee, and allowed to go home with a print out of the results, including some images.
No discomfort afterwards.
