LouLouM 70 Posted August 28, 2021 Hello. I am in the pre-op stage and an upper endoscopy was required before gastric sleeve surgery. When I had the upper endoscopy done, I also had a routine colonoscopy. They found a hiatal hernia and removed 3 polyps. This was more than a month ago and I am still experiencing periods of stomach cramping and diarrhea. I also have a lot of stomach pain, but am also stressed because I'm back to school, have a difficult class and our school has had several COVID cases (where my own children also attend). Is this stress? Could it be related to the endoscopy/colonoscopy? I had never had such, for lack of a better term, explosive and sudden diarrhea. It's not daily, but comes on suddenly, even in the middle of the night when sleeping. Thoughts? Oh, the doctor who performed both procedures suggested testing a stool sample for infection. It's been a bit challenging to do so because as I said, I've just returned to school. Will get on it though as I am not feeling well. 1 GreenTealael reacted to this Share this post Link to post Share on other sites
