Blood and Mucus after diarrhea

Looking for a bit of a hand hold and support really.
I had a horrendous bout of diarrhoea over the bank holiday weekend , which ended up with me just passing liquid before it stopped. I assumed it was down to a very glutonous Sunday which entailed a very large and delicious pub Roast Lamb dinner followed by an early evening "snack" of pate with chutneys and crackers. Along with 3 pints of beer over 6 hours.
Ive been dieting since March and generally eat "clean" apart from 2 or 3 pints overv2 days most weekends (unhealthy beer garden habit im blaming on the glorious summer we've had).
So I put this weekends upset tummy down to volume of rich food shocking my body.
I felt pretty delicate yesterday and didnt eat until 5pm.
Today I am working from home and pop to the loo for a wee, not needing a poo but thought I might pass wind. As I did I thought I had more diarrhoea but I was passing only bloody mucus.
It looked worse (i hope) in the loo with water but as I continued to wipe there werelarge dark red blobs mucus (slightly smaller than my hand). It reminded me of my show as labour started but it was full of blood.
I obviously phoned GP and have been seen already. Sent home with a FIT test and waiting for my completely empty bowels to produce a sample.
GP examined and said all felt normal but if test come back positive for blood I will need to have a Colonoscopy.

I am so scared this is cancer. Im 10 years free from Thyroid Cancer and the thought of dealing with cancer again terrifies me.
I know Ive got to just play the game and wait but im literally shaking from the shock of the last few hours.
Dr said she's sure its not an infection.
Anyone had similar and positive outcome?

Yes, I've had similar episodes. Sudden painful stomach cramping, going all hot and sweaty, gasping for breath and feeling like you're going to pass out, with 3 or 4 rounds of D, becoming more liquidy each time. Exhausted after it finishes. And every so often some blood/mucus for a day or so afterward. After all the tests and a sigmoidoscopy, I was diagnosed with IBS and diverticulosis. Apparently the diverticulae often form around small blood vessels in the colon which can burst and cause the bleeding. So there are other causes of passing blood, than cancer.

I know the dr said not infection but Could you have picked up coccidiosis? My daughter had this and was just passing bloody mucous after having diarrhoea for a couple of days.
hope you feel better soon.

A bad bout of food poisoning or gastro can upset the gut enough to do this I think.

Also, less likely, but possible is IBD which I have myself, but mine came on gradually.

I certainly wouldn’t be leaping to worries about cancer after one episode. Actually my DD had an episode of blood and mucous last week and we will see the GP but I’m waiting for our own GP to return from holiday as I don’t think a few days will make any difference and things may well just settle. Telling you this to reassure you that as someone who is very familiar with bowel conditions I feel you needn’t worry so much yet but you are doing the right thing having things investigated.

I have just been through something very similar. Had a few bouts of diarrhoea / mucus / some bowel urgency. This went on a few months and then one day after diarrhoea I saw some blood when I wiped - pinkish and mixed with mucus. The FIT test came back positive (which I should have expected as there had obviously been bleeding). I was put on the 2 week pathway for colonoscopy and was honestly terrified. Just convinced myself it was cancer. My dad had bowel cancer so I leapt to that conclusion. I was so terrified they had to wait for my blood pressure to come down before starting colonoscopy. It turned out to be haemorrhoids! Your history will obviously influence your feelings .. but most investigations are NOT worse case scenario. I feel for you and really can empathise. There are so many other reasons for some blood and mucus x

Thank you both for your positive reply. Much appreciated.
Ive done the deed and dropped off my sample kits this morning. Im 99% sure I will get a colonoscopy as there was rather alot of bloody mucus i couldn't avoid getting the samples. So now I really do sit and wait.

My tummy feels tender and I feel slightly off but im not sure how much of the feeling off is the anxiety or even my imagination.

Try not to spiral!

Your poor system has had an enormous shock. Very likely a bout of food poisoning and now your intestines are all out of whack and need to settle.

Hi, I couldn’t not comment, I’m also having some issues. Im 13 weeks postpartum and it all started about 5 weeks postpartum. I was exposed to family members who had the vomiting bug, I though it escaped it but then I got diarrhea followed by some blobs of mucus with small red streaks in it. It all cleared up for a few weeks and then happened again after a weekend away with Rich food and drink. I again saw some small red streaks. I went to gp and they tested stool for infection which was negative and calprotectin was 279 which gp said was raised but thought maybe things were related to a bug and that we’d retest in 6 weeks. I’ve had weeks of normal movements with no visible mucus and now on holidays I’m having orange mucus and I’m slightly constipated.

@Bellieboo123 im sorry you're having a few issues too. I hope this is have settled and you can enjoy the rest of your time away.

My infection test results came back clear, so its not an infection. Ive continued to gave some mild discomfort in my tummy but also think im being super aware and anxious. Ive had no obvious bleeding in the last 24hours but also not opened my bowels.
Im still anxiously waiting for the FIT test to come back.

Im worrying now about if I need a Colonoscopy when that will be (if on the 14 day pathway) as we have a 10 day foreign holiday book, we fly next Friday! I not sure what to do about that.

Hey! It has actually settled a little bit. I got my first period since my baby and I’m wondering was the last few days influenced by hormones. My stool was also negative for infection but gp did say this doesn’t rule out all infections as it doesn’t test for all bugs. I too am anxious and over analysing everything 🫠 I hope you enjoy your break away when it comes around and please keep us posted 🙏

Make sure you let them know about your holiday - I was advised at my colonoscopy this week that if they take polyps out during then you can't fly for 10 days afterwards.

I’d say it’s unlikely to be cancer just from one episode. It’s most likely due to inflammation from the diarrhoea. If it was something that had been going on for months I’d be more concerned
