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 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.

I've been sent Plenvu as my prep 😭

@Thomastuchel oh no! Is this your first ever one? Some people can tolerate it but I couldn’t. It tastes like salty mango and it made me heave. I hope you can cope with it better!

Balloonhearts · 20/07/2026 20:08

You won't be going back to work. You'll be dizzy from the gas and air, very uncomfortable and uncontrollably farting like a trumpet.

PS, some of the farts may not be trustworthy, depending on how good the prep was.

Yes it's my first prep 😬 I'm even more worried about having it now

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.

Yes they do

You won't be back at your desk sorry. You will be uncomfortable from all the air they use and want to go home and fart in private.

I didn't feel uncomfortable and didn't fart at all.

The prep I had was very salty and difficult to drink..

I bought some belvoir elderflower cordial and didn't put too much water so that it was very sweet which took away the taste of the prep.

I had plenvu. The second one is worse than the first. Keep it chilled and drink it through a straw with your fingers on your nose stopping you smelling it. That was advice from my sister, I followed it and got it down no problem. The sooner it works the sooner you’re empty and can get some rest!

Peonytimeguys · 20/07/2026 05:53

Really? I’m going to a big gig three days later - is this going to be an issue?

I felt perfectly fine after my colonoscopy. I think I had sedation, I can't even remember.

I had no wind at all and my husband just drove me home and I just had dinner and went to bed.

It was the prep. That was the worst part because it is very salty and so it is very difficult to drink.

I bought some elderflower cordial and made it up quite strong so that it was very sweet and I took a sip of that after each sip of the prep to take the taste away.

You’ll be lucky to manage without sedation and I’d be very surprised if you felt able to go back to work.

This
the bowel preparation may still work for up to 24 hrs after and you’ll be inflated with air it’s very uncomfortable I don’t think this is realistic at all

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.

I didn't fart at all. I don't know why.

Maybe you could ask to do a different prep? I've drunk picoprep tonight (I think picolax is more available in the uk and is essentially the same thing) and its not bad at all.

I wonder if I requested different prep they would send it

bringonthecrumpets · 20/07/2026 21:04

@Thomastucheli think it depends on the trust. They did send me moviprep when I told them I had used plenvu and struggled with it. It’s worth trying.

my trust also doesn’t let you leave in a taxi. It will vary.

orzo15 · 20/07/2026 21:06

Going against the grain but I recently had just a sigmoidoscopy without sedation so they only go in the lower part of the bowel, and I found it a lot more painful than I anticipated. It felt like a deep spasm pain and I was really tensing to get through it, and I would say I have quite a high pain threshold.
But I absolutely needed to go home and rest as I was full of gas and had stomach cramps the rest of the day

But how did your co workers feel ? 😂

mommaham · 20/07/2026 21:09

I get the best sleep ever after the sedation.

MustTryHarderAndHarder · 20/07/2026 20:22

Neither did I. colonoscopies affect people differently.

I didn’t go back to work as I’m retired but after resting at home for an hour or so I went shopping, then cooked dinner. I felt fine. I’m sure I could have done the desk job that I used to do.

Thomastuchel · 20/07/2026 20:58

Its worth asking, that's what I did as they wanted me to drink a prep that's 4 litres of the stuff!

Poppy61 · 21/07/2026 06:20

We are all different and if you are mentally prepared to manage without sedation, go for it. I knew I wanted sedation.

Yes, it's strange isn't it.

I would have expected some wind, but I got nothing and felt absolutely fine afterwards. I also expected to be ravenous, but I wasn't.

Bonden · 21/07/2026 09:02

No. It absolutely is not

Iloveeverycat · 21/07/2026 09:30

soleenq · 20/07/2026 20:21

Yes they do

They don't at my hospital. They ask for the number of the person who is picking you up. They have to come to the department to collect you, you just can't leave.

mommaham · 21/07/2026 10:16

On every occasion I've had these I have had to be collected by someone. Seems it varies but the drugs they sometime use can make people a bit vulnerable afterwards and the NHS do bear some responsibility if something went wrong.
