Background. Colonoscopies performed in the afternoon (PM) have been shown to have lower adenoma detection rates (ADR) compared to those in the morning (AM). Endoscopist fatigue has been suggested as a possible reason. Colonoscopies tend to be technically more challenging in female patients.
Since you can't eat solid food on the day of your procedure, it may be a good idea to schedule your colonoscopy for the morning so you don't have to wait until the afternoon or evening to eat.
We conducted a study to compare time of day and polyp detection. It turned out that polyps were common, but they became mysteriously less common as the day progressed. Early-morning procedures found more polyps than procedures conducted later in the day. Hour-by-hour, there were fewer and fewer polyps detected.
Consider an afternoon appointment
If you don't want to give up a night of sleep, schedule an afternoon colonoscopy, Lee suggests. If you don't mind doing all of your prep at once, patients with an afternoon colonoscopy appointment usually have the option to do it all that morning, Lee says.
1 Day Before Your Colonoscopy (Prep Day)
Before 10:00 am, you may have a small, light breakfast. Examples of a light breakfast are: eggs, soup or broth with noodles (no meat or vegetables), white crackers, white rice, white potatoes, white bread, Boost® or Ensure®. At 10:00 am, begin a clear liquid diet.
What if I've taken all my preparation and am still passing solid stool on the day of my exam? In this case, your procedure will need to be rescheduled. You may be prescribed a different preparation for your next procedure. Please call the triage nurse to reschedule your procedure with a different preparation.
Typically, bowel prep medication is a solution that you will need to drink starting one day before your procedure. You will be asked to take the colon prep in two doses: the first dose, 3-6 pm the night before your procedure; the second dose, 6-8 hours before your procedure.
You should not eat or drink anything after 9:30 a.m. or the procedure may be cancelled. If your procedure is scheduled for 3 p.m., you should not eat any solid food after midnight the night before but can have clear liquids until 10 a.m. of the day of the procedure.
How long does it take a colonoscopy prep to clear bowels completely? It can take 12 to 16 hours for the bowels to completely clear. Eating a low-residue, soft diet for a day or more before starting the prep can help make it easier and faster.
Eat a light breakfast today (coffee with milk or creamer is okay), but then begin a clear liquid diet. See below for acceptable food and beverages. During the day, increase fluid intake to prevent dehydration. Drink enough to keep urine clear, not yellow.
At 6 p.m., take 3 tablets of Dulcolax® laxative pill with water by mouth. At 8 p.m. the evening before your colonoscopy start drinking the Gatorade®/MiraLAX® solution. Drink one 8-ounce glass every 10 minutes until completed. You can continue to drink clear liquids until midnight.
Start the prep.
The national (and international) standard for high-quality bowel cleansing is a split-dose regimen, where you take half the prep the night before and the other half four hours before the procedure. If you have an afternoon exam, you can drink the whole prep the morning of the procedure.
You may not eat anything the morning of your procedure, but you may continue to drink clear liquids up until 2 hours before your procedure. You may shower and brush your teeth. Will I be shaved before my colonoscopy? You will not be shaved.
A few days before the colonoscopy procedure — Start eating a low-fiber diet: no whole grains, nuts, seeds, dried fruit, or raw fruits or vegetables. The day before the colonoscopy procedure — Don't eat solid foods.
The biggest culprits that will show up in a colonoscopy and obscure our view are foods like nuts, seeds and high-fiber cereals. You also want to avoid granola, coconut, dried fruit and fresh fruit with the skin on, like apples and pears, or fruit with seeds, like strawberries and raspberries.
This is a rough way to do it, but yes, you will have a very temporary weight loss of one to three pounds typically. But, just as with your bowel habits, these few pounds will return as well once you resume your normal diet.
You can start eating regular foods the next day. Keep eating light meals if you are not able to pass gas and still feel bloated. For the first 24 hours after your procedure: Do not drink alcohol.
Since the menu is low in fiber, protein, and fat, many experts now say you should resume your normal eating habits within 24 hours. Still, eating exclusively bland foods does allow your digestive system to rest and recuperate following the events of the last few days.
Remember, you can't drink anything for at least 2 hours before your procedure. You must have someone to take you home after your colonoscopy and stay with you for at least two hours.
CLEAR LIQUIDS INCLUDE: water, chicken/beef/vegetable broth, flavored waters, apple juice, Jell-O, Kool-Aid, coffee, tea, Sprite, Gatorade, PowerAde, Mountain Dew, Coke/Pepsi, Rootbeer, and Slurpee's. DO NOT DRINK milk or use any dairy or non-dairy creamer in your coffee or tea.
We ask that you start the bowel prep at the time we gave you. But if you do start one or two hours earlier or later than the time given you, that's fine as long as you follow the clear liquid diet for the day.
DAY OF COLONOSCOPY
bowels at least 10-15 times. By the end of your prep, your stool should become a clear, yellow-tinged fluid. scheduled, but then nothing by mouth after that.
