I have had 7 colonoscopies over the last 3 years, resulting in 2 bowel surgeries for colon cancer. Removing haemorrhoids will not be done at that time.
I did not find the prep awful; it is just having to drink so much volume over an hour or so, and repeated once more over another hour or so. You will feel the urge to get to the loo by the end of having drunk the first sachet of prep, and it will continue for a few hours after you have finished the second sachet. You need to drink extra water with the prep. You will find that towards the end of the prep you are passing less urine - hence the need to drink more water/clear fluids throughout the prep.
In my area, for 24 hours before the camera, I was told not to drink milk or blackcurrant/ribena juices. Water, black coffee, black tea, herbal teas are ok. I liked mint tea, so I had that, and I like drinking water. Your diet for a few days before is important, it needs to be low residue, and the leaflet provides lots of ideas for meals.
Of all my cameras, my preference is for an afternoon appointment. This means that the previous afternoon is taken up with the prep, and I finish going to the loo by 11pm or so.
Wake up in the morning, loo again, and I just drink water or mint tea. Morning appts are very rushed I find.
I request sedation; Midazolam is used where I live, it is a small amount and it reduces any anxiety about the procedure. Mine were painful and I was given a small dose of Fentanyl. I did not have sedation or analgesia the first 2 times and they were very painful, however not everyone has pain.
My bowel was very twisty/tortuous and that probably explained the amount of pain I had. But I could not forget the pain, so I have had analgesia each time afterwards. Neither sends you to sleep, just comfortably carefree. They also may give you some Buscopan through your IV access, it relaxes the bowel, and helps the endoscopist perform the procedure.
Staff at my unit are mixed sex, and once were all women. All were extremely caring. I watched all on the big monitor, and everything was explained.
I was given a printed result the same day, excluding any biopsies of course. There were pictures taken of areas of interest or where biopsies were taken from. Follow up was also mentioned, along with any other plans/referrals.
Cup of tea and sandwich, then home. Someone to take me home if I had sedation and analgesia. Generally I slept for a couple of hours and fine later on. If you don't have any meds you can drive yourself home.
I hope not too much information, but this was my experience.
