Other options: There are many preps available. Options will vary with the endoscopist. It is best to discuss this with your doctor as he is the one who will advise you on the prep.

What else can I do for my colonoscopy if I can't drink the golytely (polyethylene glycol)?

Enema: The purpose of the Golytely (polyethylene glycol) is to clean the bowel so that on passing the scope the endocopist can define small lesions with no obstruction from retained stool. The Golytely (polyethylene glycol) absorbs water into the bowel acting as a cleansing agent. Any replacement will suffice, that is by an oral intake free of roughage for several days, clear liquid diet 2-3 days before, the use of Haleys MO and a Fleets enema ...Read more

Lot of miralax (polyethylene glycol): Regurgitating too much miralax (polyethylene glycol) is not uncommon if the stomach gets overloaded and cant handle the volumn injested. I prefer GoLightly which adsorbs fluid into the small bowel and secondarily cleanses the colon. In spite of everything I still suggest a Fleet enema before going for the procedure. ...Read more

Having problems with constipation, bloating and loss of appetite. Miralax (polyethylene glycol) causes me to burp alot. I had a colonoscopy l-l/2 years ago that was normal.?

Diet: If you have had a full work-up for your constipation, including lab tests.
