Bloody mucus and painful cramping after endoscopy and colonoscopy ( with biopsies )

Posted , 4 users are following.


I have undergone diagnostic endoscopy and colonoscopy a day back(yesterday).  I am on low residue diet and drinking good amounts of water. I had the urge to have bowel movements yesterday but there was only bloody mucus with a lot of cramping.

Today morning as well I had multiple urges to go to stool more than a dozen times but most of the time it is bloody mucus. Sometimes it's a small lump of stool and bloody mucus together.

Since today was a weekend, I tried to reach a doctor on call who mentioned that I should fine and was advised to drink lots of water and reduce the food amount. I wasn't able to get help on what would be an ER situation.

Did anybody have a similar experience after colonoscopy with lots of cramping and bloody mucus?

    Did they find a polyp ?

    As they can cause bloody mucus.

    Not sure about the cramping though.

    If pain carrys on you should see your GP.

    I had my colonoscopy five weeks back and had biopsies .I was told that i will see the blood when i go to toilet but mine was fine and had no cramps of much blood as well, Yesterday i had endoscopy done and i am fine , i have no after effects.

    I was told by the nurse after the colonoscopy that if i have lots of blood and cramps or feel unwell then go to A& E. But as i said i was fine. I had done both in a private hospital. My doctor is excellent and i have him since last 18 years as i have chrons.

    so far i had 5 colonoscopy. Have to it every three years.

    Hope you will be fine soon.

    Thank you

    Thank you

    Yes, I have problems like this after and that is one reason I don't go in very often. I have Crohn's disease and it takes me a while to heal after so many samples were taken. The lack of stool is normal as you are cleaned out before the scope, but it will come back and things will normalize after a week or so. It takes me a month to get it to stop, but that is me. As long as the bleeding isn't super heavy I wouldn't worry too much. Ask your doctor for some medication to stop the cramping. Hang in there it does get better, but if you develope a fever or vomit then go to the doctor.
