I've had 3 others with the same prep. I didn't have gastritis with those. I was diagnosed with gastritis in July of 2024 with an endoscopy. I have bad anxiety and l think my nerves get the best of me. I decided to call the doctor and spoke with his medical assistant. She said it has nothing to do with colonscopy as it came out good other then finding a very small diverticulosis area. My concern after Googling to much is reading about perforated colon. She told me with that the pain so very bad that you can't stand up. I think my anxiety isn't helping either. I've gone through 3 colonscopy before this and my anxiety didn't get so bad. Maybe it's getting older. I don't know.
