What kind of food can I eat the day before my colonoscopy procedure?

What kind of food can I eat the day before my colonoscopy procedure?

Liquids: No solid or soft foods ar allowed on the day of the prep. Any liquid that you can see through (clear liquids) is allowed--tea, black coffee, water, juces without pulp, broths, popsicles, hard candy (ie, jolly ranchers). Avoid any red colored fluids as they may give the tissue a bloody appearance and can be confusing. ...Read more

Is it okay to smoke before a colonoscopy?

Is it okay to smoke before a colonoscopy?

Also: In addition to the obvious concerns, smokers usually cough a lot during anesthesia for colonoscopy, and this makes it more difficult to do a good exam. Its best if you quit altogether, but if you can avoid for a week or two prior to colonoscopy (or any surgery) you will have a better outcome. ...Read more

Should the laxatives be taken one day before colonoscopy or on the same day a few hours before the start of the procedure ?

Should the laxatives be taken one day before colonoscopy or on the same day a few hours before the start of the procedure ?

24 Hour Prep: Your GI specialist is supposed to provide you a sheet with instructions to clean your bowel. You need to avoid any solid foods for 24 hours before the procedure. During this time you need to take laxatives till your bowel movements are entirely liquid and free of any residual fecal matter. Drink plenty of liquids during this time, to avoid dehydration. Good luck!. ...Read more

Can colonoscopy aggrivate internal hemerhoids? I had no pain or external before procedure. I had pain 6 weeks in anus after, I have had piles 4 3 months

Yes, but......: The bowel prep used prior to colonoscopy can cause hemorroidal flare up, but pain for 6 weeks may indicate that you have an anal tear (fissure). Also if the piles have not gone down for 3 months, you may have thrombosed ext. Hemorrhoids. You should be evaluated by a surgeon. ...Read more

I will be taking Nu Lytely prep for my colonoscopy. .I am also taking Metformin ER 500mg. Should I discontinue my Metformin before my procedure?

How are your sugars?: we usually worry about hypoglycemia a lot more than hyperglycemia on that day before - especially that you'll be on clears only and may or may not be getting a lot of calories in. we usually have people take 1/2 their usual dose - more if they're poorly controlled and none if they're already pretty tight. definitely don't take it the morning of (unless again, you're running 400+...) ...Read more

I had a colonoscopy yesterday. The diarrhea has not stopped since taking the MoviPrep the day before the procedure. Can I now take an anti diarrheal? Is there anything else I can do? Thanks!

Yes, yet patience +: wash gently almost certainly the wisest option. Quick "fixes" are widely marketed and make lots of money for those selling them. Yet that does not mean that using them, in most cases, is wise or accurate thinking, other than having less money to spend on other issues, hopefully of more value. ...Read more

I accidentally drank red jello juice day before procedure. Did I taint II for colonoscopy procedure?

Yes possibly: Notify your doctor and discuss rescheduling. Let the gastroenterologist make the call on whether the results will be affected. It is important not to line the colon with red stain because it can be misleading. ...Read more
