Colonoscopy - Need low residue and fluid diet suggestions

21 replies

AlltheprocessedFood · 23/09/2025 16:58

Help!
having a colonoscopy and need to do a low residual diet and the 2 days of fluid only. It just says yoghurt drinks and strained soup. It’s the opposite of my usual salad and veg based diet. Any suggestions as the pack that came with wasn’t very helpful.

All I was allowed when I had mine 2 years ago was clear boiled sweets (such as foxes glacier fruits) but NOT blackcurrant ones, and light coloured squash such as lemon.

I’d have been thrilled with yogurt and soup! 😂

I had a colonoscopy today, I am recovering just now. The bowel prep experience is ROUGH please have someone with you for this, to hold your hand.

meanwhile eat lots of white bread, chocolate mousse, low salted crisps like Pom Bears, plain crackers. Fresh orange juice for a sugar boost. Scrambled eggs
full fat milk

all the best for you

eggs, cheese, tuna mayo

You can't have anything red / purple l(ike sweets or squash or ice lollies) - I think the dye can affect the colour of your innards and make them look dodgy.

I'm surprised they said yoghurt - I'm sure I was told no dairy!

Plain white fish, plain chicken breast (no fat). Clear soups such as consommé.

Plenty of nhs guidance online about low residue diets.

Plain jelly (no fruit bits), black tea or coffee.

Did they not give you guidance about what to eat?

I remember being told that cauliflower was OK with my first colonoscopy...boiled only.

PineappleCoconut · 23/09/2025 17:55

I mainly ate white bread, white bread toast and clear chicken packet soups (strained) for the 2 days before. The prep was so much easier if you hadn’t eaten a lot for 2 days. I even went to work between prep after the hour on the loo.

For the prep day itself, I froze the moviprep to nearly slushy consistency, drank it through a straw with a chaser of sugared lemonade.

@MousseMousse thw page literally just has 4 lines and says tea/coffee, strained clear soup and yoghurt drinks!

Wow, they used to give much better information (going back a long time!)

If I remember rightly - and it ties in with what another poster has said - a couple of days before it was clear, strained soup, a piece of white fish or chicken (boiled) - and then the day of the laxatives it was clear liquid only - water, nothing with milk.

You could ring the department and ask some questions, maybe they're more relaxed about it than they used to be 🤷‍♂️

When I had it you could have bread, spuds, crackers, cornflakes, eggs. Basically plain food with no fibre, fruit, veg etc....

CharlieChaplin99 · 24/09/2025 01:38

Think it was eat very plain low fat no dark foods.

The bowel prep was grim. But do refrigerate it. Do drink it from the times stated and do drink it all.

Don’t have anyone with you evacuate the house. I felt so weak with all the motions and the efforts of going to the loo but survived it. I also had maximum sedation and got my brother to pick me up so slept all afternoon.

It wasn’t as grim as I thought with the sedation and all the staff were lovely.

AlltheprocessedFood · 24/09/2025 12:09

I’ll be phoning today to double check. They seemed to push the gas and air option over sedation

Some people find colonoscopies fine without anything, I think it can depend how far up they're going, but if you want sedation then you can have it

I had a double inspection at the same appointment endoscopy and colonoscopy. I was very nervous about both and the sedation helped calm me down and to take the edge off with both procedures. Neither was anywhere as bad as I was expecting with the sedation.

Take care

I ate a lot of rich tea biscuits. 😂 Never something I ever would have bought, but now I quite enjoy them.

eggandonion · 24/09/2025 15:19

My list says madiera cake is ok. I'm unreasonably excited about that. All the lists are different so I should stick to my madiera cake and not Google 😎

My daughter's just had one, so reading back through her notes. She was told low residue diet from 2 days before and then nothing but clear fluids for the day before (consomme, clear mints, lemonade, definitely no dairy). I spent ages making chicken consomme, which did not get eaten!

HarryVanderspeigle · 24/09/2025 17:57

The timings to stop eating depend on what time your colonoscopy is. It's clear liquid only after that, but you are unlikely to want anything more than water, as it puts yiu through the wringer. If you want sedation, just ask for it. Not sure why they would be pushing just gas and air.

I did too!

I think for about 3 days before I gave up anything with seeds or grains or fruit with skin and then the day before was nothing from about lunchtime (my appointment was the following morning). I think I had white toast for breakfast and then ate ice lollies (not red/purple as a pp said).

Beige diet - the one time you can without guilt :)

With the bowel prep, make it up in advance, and put in fridge. Label it so you know which one to have first. And use a straw. I took it with (clear) apple juice "chasers".

All the best I hope they don't find anything or if they do it's easily fixed and gets rid of your symptoms.

I had one recently. I was told low residue for a few days before. For me that's eggs, white potatoes, white pasta, rice, chicken, white bread, yoghurt. Then clear fluids. Consommé, boiled sweets, strained fruit juices, tea or coffee with no milk - but nothing red or purple.

Mayhest · 24/09/2025 18:12

You can get away with strained chicken noodle soup if you don't like consommé.
