I hope this information is helpful for WLS patients who need to have a colonoscopy.
I have one scheduled for Wednesday. After telling my gastroenterologist that I had WLS and have significant nausea problems, he prescribed Suprep for my colon prep. With Suprep, you have to drink 4L of water, preferably in one hour. I know I won't be able to do this, so I searched online and found medical articles that said bariatric patients can take longer to drink the 4L since their stomachs are so small. https://consultqd.clevelandclinic.org/which-bowel-preparation-should-be-used-for-colonoscopy-in-patients-who-have-had-bariatric-surgery/ . But the article stated that the authors prescribed a 2L alternative, Moviprep, for bariatric patients because it is much more easily tolerated.
What upsets me is that I didn't find out about this until after I had purchased the Suprep. To even make matters worse, I found an article from the American Journal of Gastroenterology showing that of the three most common preps -- Miralax, Moviprep, and Suprep, "Miralax was successful in 87%, compared to 74% for Moviprep and 69% for Suprep" in adenoma detection rates. https://journals.lww.com/ajg/fulltext/2013/10001/comparing_miralax__versus_moviprep_versus_suprep.548.aspx
So I am really frustrated and upset right now. Not only will I have to drink double the fluid amount that I could have, had my gastroenterologist prescribed with consideration to my WLS, but I have to take the prep that has the lowest rate of adenoma detection.
I scheduled my last colonoscopy in the afternoon, because I know with those, they have you drink half the fluid the night before and the other half in the morning. Figured that would be do-able, and
