Colonoscopy without sedation

Hi everyone, I’m writing this to reassure anyone that may be going for a colonoscopy and is wondering what the the prep is like, how does it feel and what to expect.

I went to the GP with changed bowel habits and some blood in my stool, she referred me down the two week cancer route, so I was scheduled for a colonoscopy within a fortnight after my initial consultation as I had similar symptoms as a person with bowel cancer would have.  Now I’m a 32 year old female so it’s unusual for someone of my age to have bowel cancer as a rule of thumb it usually affects older people (not always the case but you may take some comfort in that!), even knowing that I was still petrified why they had sent me down this quick cancer route - did they know something I didn’t, I was really worried about it to a point I nearly cancelled the whole thing - ignorance is bliss and all that!

I didn’t cancel, I got given my prescription for the MoviPrep collected it and arranged the time off with Work.  Now my appointment was at 2pm, so the day before I ate as normal, avoided red meat, and kind of stuck to the guide they gave me.  I was meant to stop eating at 1pm the day before and I was literally cramming a chicken baguette into my mouth at the last minute.  I got home around 5ish and began my prep at 7pm, I had a split dose, one litre the night before and one in the morning.  Now I’ve heard real horror stories about MoviPrep, and let me tell you I didn’t experience any.  The taste really isn’t that bad, it’s a bit like salty lemon, I wouldn’t go buy it from a shop if I had the choice, but it’s really not that bad, I just chugged a glass of it every 15 mins until the litre was gone.  Now then even after 3 hours I only had one bowel movement and that was it.  I had a bit of stomach cramp (it does make you bloated!) and I went to bed with the idea in my head to call and cancel in the morning if the second lot of prep didn’t work!  The bonus with MoviPrep is it fills you up so you’re not hungry either, I went to bed woke up at 6 and began my second litre, now during the second litre is when movement began to happen.  For me I found it easier to just sit on the toilet for a solid hour, I didn’t get any stinging as some people do, but by the end when you know the MoviPrep has done it’s job it is literally like having a wee through the other end where nothing but clear liquid comes out.  Now I was concerned because I didn’t get rid of that much and still  convinced it hadn’t worked, but reset assured it had worked and I just didn’t have a lot in my bowel in the first place! 

The moviprep finished about 8:30am then I started to get hungry around 9:30am.  By then everything is out and you’re just waiting, I wasn’t allowed water after midday so I kept my stomach full by drinking plenty of water!  On a side note prior to no liquids and during the time of no food you can have clear liquids, so I treat myself to a glass of white wine (not red it’ll stain your bowel and may be mistaken for blood) the night before. So all in all the prep wasn’t bad.

I arrived at hospital for my appointment, waited 30 mins saw the nurse who explained everything checked my vitals that I’d had my prep, no food or water etc. I then get handed these shorts with a opening in the back, get changed into them, put my pants back over the top and wait again, I reckon by 3pm the doctor came out, introduced himself, went through the consent and asked if I wanted sedation (I didn’t) and said when you’re ready come in. 

So I went in, took my pants off, they keep everything under your bed, there’s a monitor so you can watch and nurses there checking your vitals etc.  So they hand me Entonox (gas and air) and insist you take 5 breaths before starting so you know how to use it, after 5 I was already light headed.  So this is where it begins, you can feel it; it’s uncomfortable and rightly so as it’s not a daily occurrence but it was not painful, at some points especially the corners you can feel it, he asked if I could lie on my back at some point and my front to make the camera round into smaller corners, and the sensation I imagine (I don’t have kids) would be what a baby kicking would feel like.  In total it lasted 30 mins, I was watching and chatting to the nurses during it, I think I hit up the Entonox 3 more times (singular times) but that was it and I probably could have done without it.  So rest assured it is not that bad at all, now everyone’s pain threshold is different and all bowels are different so it may be more difficult to navigate through other ones.  But if you’re scared about it and in debate over sedation then I hope this eases your mind a bit!  I think the Entonox would be sufficient enough for me it was anyway.  So we’re at the end, during he says the moviprep worked really well, had a clean bowel and there was no anomalies, they didn’t find anything what so ever!  He explained that he’s taken routine biopsies as he may expect to find a minimal trace of IBS but that’s it, and that can be remedied with diet.

Afterwards they wheeled me out into the recovery ward, I get dressed straight away, go sit down to a glass of water and cheese and crackers (the best cheese and crackers I’ve ever had after 28 hours not eating!).  They do say if your bowel is full of air release it as it’ll cause discomfort later on, now I know during the procedure he was pumping air in for a better view so i was expecting some, but nothing.  I felt 100% fine just hungry and thirsty.  After 30 mins the nurse went through my report, explained a few things, asked how I felt, checked my vitals and I was free to go.  You can drive after, I went home had a pizza, drinks and went to bed.  Woke up fine the next morning and went back to work.  I had no discomfort afterwards, I wasn’t in any pain it was like it never happened.

As I said everyone is different, but I read so many horror stories before mine which probably didn’t help prior to having mine, but if you’re trying to scour the internet for information as I was I hope this helps! Any questions just ask!

  • Thanks for this info. I had my first colonoscopy before Christmas after severe bleeding. As I didn't know what to expect I decided to go for sedation. I actually don't think I felt any different when they sedated because I didn't feel sleepy or anything and was fine the rest of the day. 
     

    They found a large polyp which was too big for her to remove that day so they took a biopsy. Thankfully it's come back all clear. 
     

    I have now been booked in for the colonoscopy polypectomy to remove the polyp next week and I just don't know what to do now whether to have sedation or not.  I'm not sure whether because it's a large polyp and might take longer to remove whether it would be good or not or whether I still won't feel too much (the only pain I felt first time was when the camera goes around the bend of the bowel). The polyp is only 20cm inside so they don't have to go far. I am in such a dilemma.

  • I had my colonoscopy this morning at 10-15 without sedation,this was my second one and I must admit if I had gone through the same pain last I guess I would have had sedation, for the simple reason the pain was quite unbearable I really thought I was going to pass out I had the gas and air with little affect it felt I was in there for hours I wasn't just felt like !!! I don't know why it hired so much this time ,because I felt hardly anything last time a little discomfort which is expected. I don't want to put anyone off getting this procedure as it's lifesaving.

     

  • I found this thread very reassuring, and have registered to share my own experience in the hope that others might be similarly reassured.

    I had a colonoscopy last Sunday, with just four days' notice so there was little time to worry about it.

    Three days before the procedure I started eating only light, simple meals - cornflakes, white fish, baked chicken breast with white rice - and didn't eat at all for the final 36 hours. This made the bowel cleansing much more pleasant, and I had no problems at all with the MoviPrep. I did, however, have very frequent, liquid bowel movements for six hours after finishing the second sachet, so I would advise against taking it too late in the day.

    I decided against having sedation, because I didn't want to feel drowsy for the rest of the day (it was an 8am appointment), and the procedure was a breeze. The endoscopist said that she would go more gently and slowly than usual to allow for the fact that I wasn't sedated. The staff placed the entonox nozzle close to hand so I could easily draw on it if required. There was no pain, just occasional discomfort and couple of brief moments of what I would call severe discomfort which were alleviated with a couple of puffs of the entonox. I was only rarely even aware that there was a tube inside me.

    The entire procedure lasted less than half an hour, and I was on my way home again less than 90 minutes after arriving at the hospital. I had no discomfort or soreness whatsoever, though it did take about four days before my first bowel movement.

    I realise that everyone is different, and that not all procedures go as smoothly as this one did, but I would have absolutely no hesitation in doing it again without sedation.

  • Hi everyone 

    I am due to have colonoscopy in March. My consultant offered the choice of this or a CT colonoscopy. From his examination he doesn't think there is anything sinister going on. I have had IBS for years, I am now 51 and he also said because I have bloating as a symptom I may not be able to tolerate colonoscopy. I don't know which option to go for. The coward in me is thinking the CT scan but should I just go for whole colonoscopy. Im scared of the thought of it and worried that the procedure might not even be possible for me. 

  • Sorry to hear of your troubles. Although some folks here describe the process as ‘painless’, not everyone does! If both yourself & doctor think the virtual colonoscopy is the way to go, accept it. I understand that the results are equally good in either case & a whole lot better than for a failed colonoscopy.

  • You have done the hard part! If you could handle the inspection, I am sure you can handle the removal. I would definitely have the sedation though. 

  • Thank you. I actually had it removed 5 weeks ago and thankfully it's now been tested and entirely benign. I did go for sedation again and it really didn't work. Because they had to work hard in it was it was a large polyp (4cm) the air caused me so much pain. Was awful. But worth the pain to know it's ok. 

  • Thanks for writing that post - it convinced me not to go down the sedation route, despite getting myself into a bit of a state the night before reading all the horror stories! 
     

    I did find it painful - no getting away from it. I was groaning all the way through (lasted about 30 mins) and had a LOT of gas and air. I occasionally got high / spaced out to the point where I was reminded of a festival a few years back (!!), but I wouldn't say it made the pain negligible. It definitely helped though, and afterwards I was glad to be able to leave the clinic quickly and with a clear head, so overall, I feel it was the best decision. The pain was a 6.5/10 on my scale (no childbirth to compare it to though!). Like REALLY severe period pain, but nowhere near as painful as a 6 week medical abortion I had one time (it was that experience - of which I'd had no warning of the potential agony I was about to inflict on myself - that made me so suspicious of the clinical advice for the colonoscopy. I tend to think they have to play down any pain or no one would get anything done, but I'd definitely have preferred to have known in advance how painful the abortion was likely to be). 
     

    As for the colonoscopy, I was definitely relieved once it was finished. I also struggled generally with having someone (a man of course ) fiddle around with my bottom - it's a loss of dignity whether it's in a medical setting or not. It didn't help that when he turned the bend (painfully, as apparently I have a very twisty bowel) that he started complaining there was 'debris'! Slightly mortifying, but my own fault for not reading about the low fibre diet you should have the days before the prep. Sweetcorn isn't easily digestible! 
     

    My results were clear and I hope to never need this procedure again. I still question why in America only 2% of colonoscopies are performed without a general anaesthetic. It feels like nhs cost cutting to me. That said, should I ever need one in future, I won't be terrified, just keen to get it over quickly. 
     

    Best of luck for anyone going for this procedure and well done to those who got through it!

  • So I had my colonoscopy yesterday and I was so so scared.

    I think mine was the fear of the unknown as I had no idea what it would feel like ect. I had also read so many horror stories of people stopping the tests ect half way through and that was with sedation. 
     

    I opted for no sedation and no entinox purely because I hate the way they make me feel. My colonoscopy from start to finish lasted 18mins with biopsies taken. To be honest there were quite uncomfortable parts, but nothing that isn't bearable. They found ulcers in my small bowel so now have to go and have a capsule endoscopy as they suspect Crohn's disease. 
     

    also the most uncomfortable part is moving up the colon and going round the bends, which they do quickly as they do most of their looking and investigating on the decent, the decent is completely painless and not uncomfortable at all.

     

    Your actual colon has no pain receptors inside of it so the discomfort is actually from the air they use to help navigate around the colon. The air pushes on the muscles on the outside causing the discomfort. It also tricks your brain to think you need a poo. So you might also get a strange sensation that you feel like you're going to poo yourself but don't worry you're not!  
     

    if you're looking this up because your due to have a colonoscopy, please don't be scared of the actual procedure. I personally thought the bowel prep was 100 times worse than the actual procedure and that was mainly because it was inconvenient to keep going to the toilet all night. Deffo have wet wipes, cream and a book ect to hand. 
     

    just thought I'd share my experience to hopefully put some people's minds at ease. I'm a 29 year old female who in honesty is a bit of a wimp so if I can do it, so can you! 
     

     

  • Thanks for sharing this experience. I feel you may be correct about the inflation gas causing most of the pain. In my own account I mentioned being stretched like a balloon & being told that there was no way to let any gas out, only in! This seems like a real flaw in the process. What did not help at all was the theatre assistant using her (sharp) elbows to try to force gas out. This was never going to work but it was seriously painful. The other strange thing is that most people are made to lie on LH side so that the transverse colon is actually pointing uphill. That means that the camera must be forced upwards at one stage. The moral of the story is that Entonox simply doesn't work for most people.
