Colonoscopy - is it ok without sedation?

I have to have one next week and I really don't want sedation. It's early morning, and I'm hoping I'll be back at my desk by 1pm. They've offered gas and air, or even sedation mid way through.

Wld love to hear if people have gone through it without, but perhaps its a person to person thing.

I opted for the CT colonography first after a positive FIT, as I really didn’t want the colonoscopy.

In retrospect the wrong choice, as
I still had to do the prep for this too
They did not offer any sedation.
They inflate you with even more gas than the colonoscopy which I found excruciating, particularly without the sedation.
No one can hold your hand in the CT room
And then I had to go for a colonoscopy anyway to remove the polyp they found

I thought it was the easier option and it really wasn’t. Just meant I had to do the prep all over again, and go in for a colonoscopy later, and have the stress of waiting as well as knowledge that I’d have something up my bum again, and still didn’t have a definitive answer as to why I had a positive FIT.

Can I ask what the reason for your positive FIT result was in the end please?

No, a CT scan is not really an alternative.

A CT scan is not as accurate and if it does show anything unusual you then still have to have a colonoscopy anyway (to have a proper look and take samples etc).

you also need to do the same prep for a CT scan.

It really is fine. Much better than dying!

Please don’t spread misinformation. The CT of your colon is now being offered as an alternative to a colonoscopy in many cases. The prep isn’t as bad, and it’s very useful to prevent colonoscopies where not needed.

Which bit of the prep is awful? The laxative drink?

The taste and the texture for me of the drink 🤢 And the sheer volume of fluids you need to drink.
Yes you can get a bit sore from wiping etc, get some wipes in and some vaseline.

Interested in this thread?

polyps
A smaller one was later found to be cancerous, which we weren’t expecting, but caught very early.
I did choose a resection and lymph node removal to make sure, it was that or even more frequent colonoscopies.
All clear now.

Just wish I’d gone straight for the colonoscopy rather than the CT one first. It added another wait, which didn’t help my anxiety over the whole process.

I am a pro at the bowel prep now Grin

The drinks aren't great, I've tried various ones but your bum gets so sore from the aftermath of the prep!!

Highly recommend vaseline your bum from the first 'go' and keep putting it on every time to protect it!

Those of you who have had one- can you have someone with you?

No you can’t

I work for myself, from home, so I don’t need to go to work per se, but I would like to work if possible that afternoon as I’m hugely busy

I have had several colonoscopies, all of them with some sedation. I was absolutely fine and back to normal within an hour or so.

on one occasion I had no one to drive me, so I just told them that I was waiting for my husband to collect me. Sat in the waiting room for half an hour, until I felt confident that all was well. Went to the loo and quietly slipped out. Drove home and had a cuppa.

What a stupid thing to do.

Might as well do operations with no pain relief because why not.

Sedation isn't pain relief, it's to calm so you can tolerate your colon pumped full of air and don't stop the procedure

There is a pain relief component to the sedation. Most hospitals give fentanyl which is a strong analgesic and buscopan which stops the bowel contracting in addition to Midazolam which is the sedative.

AppleDumplingWithCustard · 20/07/2026 15:20

No it wasn’t. It was light sedation, which is normal for colonoscopies. I was never not aware of what was going on. Even watched the screen during part of the procedure. By the time I got into the car at least two hours had passed and I was perfectly fit to drive.

Giraffestory · 20/07/2026 15:32

take the drugs - the air being pumped into you will be as painful as hell.
you will have the shits - albeit runny - BIG TIME after

AppleDumplingWithCustard · 20/07/2026 15:39

You may feel fine but the sedation stays in your system for up to 24 hours and can impair your reflexes, co-ordination and judgement. It can be detected in your urine up to two days later. But you obviously know better.

Good grief, the more I hear and read about colonoscopies, the more determined I am that I will NEVER have one. I know a woman who was told she needed one (after blood in poo) and she refused it, (for several personal reasons,) and had a CT scan with contrast.

If I ever need my bowel/intestines looking at, it will be a CT scan for me. I know a few people have come back with 'it wasn't too bad' stories, but too many have come back with 'err yeah it was.' There is an alternative to this.... Why are more people not asking for CT scans instead?

I had a CT scan which was quite uncomfortable. The gas they use to inflate your bowel makes you feel like you want to poo. You can't poo because the prep has emptied your bowel. The prep you do is similar to the one for the colonoscopy, but not quite as harsh

They found polyps via the CT scan so I had to have a colonoscopy to remove them anyway.

I had sedation for the colonoscopy but just felt relaxed and not out of it. There were only two moments of pain. First, when the camera was going around the first bend and at the end when they turn the camera to look the other way just before they remove it. I watched on the screen when they were removing the polys. They found more polys then they showed on the CT scan and said that the CT doesn't also show up everything. I didn't feel anything when they removed them. The whole thing wasn't unbearable. I suppose it depends on the state of your bowel. My friend has diverticulitis and found it very painful.

I felt fine straight after the colonoscopy but had to stay in the recovery room for an hour. My DH drove me but I felt like I could have driven. I didn't go back to work.

The preparation was worse. The stuff you drink tastes awful and you need to stay close to the toilet whilst it is working. The prep didn't cause any pain - like you would have if you had a stomach upset.

Iamnotavicar · 20/07/2026 16:05

I've had one colonoscopy and that was without any sedation. I found it to be mildly uncomfortable but bearable. For me the worst bit (as others have said) was the prep beforehand, ye gods!! The procedure itself was fine, if a bit odd. And the staff who did it were very kind and gentle too.

AuntieGrizelda · 20/07/2026 16:13

Sorry, mistake on earlier post. I had a CT colonography which involves prep and air up your backside

tempname1234 · 20/07/2026 16:51

I have to have them every 3 years and I always have many polyps removed during the procedure

I practice meditation. It helps me through the procedure without sedation. Being calm in yourself, breathing deeply and slowly, exhaling the same way will help you through it.

it is drinking the ghastly prep and all the pooping that is the issue. Start now reducing certain foods and your prep will go much better. Read up on the 7 day diet before colonoscopy. Very much helps the clean out process.

BeSharpHelper · 20/07/2026 16:59

I have worked in endoscopy and I would recommend the sedation. Everybody is different internally and if you have lots of bends it’s going to hurt. They will put a cannula in anyway , so you can always change your mind halfway through if you need to . You will also fart afterwards, a lot. So if you work with others im not sure how you will navigate that.

RandomNameSelection · 20/07/2026 17:02

I’ve had 3, 2 with sedation and one without. Would never have one without sedation again. Apparently I have an “bit of an awkward bend” to get round 🙄 With sedation I find it find, just in a slightly dreamy state; without sedation it was horrible - like really really bad wind. I gave birth to DC2 without pain relief but I remember the non-sedated colonoscopy as being worse.

Imlyingandthatsthetruth · 20/07/2026 17:09

Well... the prep is shit (pun totally intended!), so reward yourself for getting through that with sedation for gawds sake! The medical preference is sedation (well, I should only speak for myself, of course), and there will be a reason for that.

I had a CT scan which identified a polyp. That still requires bowel prep and a probe deep up the bum. That was followed by the colonoscopy.

Good luck.

WhatWouldMyMamaSay · 20/07/2026 17:14

I have them every couple of years, and have had them twice with gas and air.

First time was uncomfortable but we got it done.

Second time was still very uncomfortable and verging on painful that we had to stop and reschedule with sedation.

bringonthecrumpets · 20/07/2026 17:19

I have had more colonoscopies than I can count as a result of cancer. Ask for moviprep if you can as the other option (plenvu) tastes vile and can make you sick. Eat rice / pasta / bread on the 2 days leading up to it and then fast for 24 hours. Follow their instructions depending on the time of the exam.
I always take sedation and would recommend you do as well.
@PrettyLittleRosea colonoscopy can detect a polyp 10 years before it becomes cancer and you have it removed straight away. It’s an awful procedure but does save lots of lives.

I will have one every year for the rest of my life and as much as I hate it, it makes me feel safe. All the best of luck.

Iloveeverycat · 20/07/2026 17:24

I can get a taxi home if I get sedated.
You can't get a taxi home you have to be picked up. They will not let you leave.

Iloveeverycat · 20/07/2026 17:29

For me drinking the prep was really easy and the after affects.

RanchRat · 20/07/2026 17:48

I have had very many. I did not like the sedation because it only partially works and I was aware of the pain. Gas and air worked really well but you have to really pull on that sucker to not feel the pain. Everyone is different though and for some people it does not hurt much.

Borntobeamum · 20/07/2026 18:17

After bowel cancer, I’m rather a pro at colonoscopies but they still put the fear of god in me.
The first one, gas and air only, I passed out from the pain.
since then, I have optimum sedation plus gas and air and it’s still excruciatingly painful.
I’m also told not to drive or work for 24 hours.

I appreciate not everyone is as bad as this but I certainly wouldnt bank of being back at your desk by 1pm.

spiderlight · 20/07/2026 18:42

I've had five, all without sedation - they're unpleasant but bearable for me, once the prep is out of the way (start it a couple of hours earlier than your letter says though - I had to do a dash from car to hospital toilet that would have made Usain Bolt proud last time!!). You will not be back at your desk that afternoon though, I suspect - you'll be washed out from the prep, which is also likely to disturb your sleep, and they'll have to inflate you so you're likely to have a lot of windy pain for the rest of the day. Good luck with it - it's not a fun morning out but I'm so grateful that they're available.
