One of the most common questions we get at CRS is “how do I know if my bowel prep is working?
When prepping for a colonoscopy your doctor has probably talked to you about how important the bowel prep process is for accurate results. Residue left behind can make it harder for the doctor to view your colon during the exam – meaning a polyp or other issue might not be seen as clearly or even missed.
And no one wants to get to a colonoscopy appointment and be told their prep didn’t fully empty the colon and they’ll have to do it again.
So how do you know if your bowel prep isn’t working?
When To Call Our Office
- If it has been more than 4 hours since you started bowel prep and you aren’t feeling the effects
- If you experience persistent nausea or vomiting during preparation
Everyone Colon Is Different
Many people start their prep and expect something to happen within minutes– but everyone is different and for some people, prep just takes longer to begin and complete.
For the average patient prep takes about 6-8 hours to complete, and often women can take longer than men. Women often have longer colons due to childbirth or hysterectomies, so it can take more time for material to travel through the colon.
Generally, if you’ve started prep but haven’t felt the urge to go to the bathroom after an hour, there is no cause for concern or a call to the doctor’s office.
However, if it has been more than 4 hours since you started the bowel prep process and you aren’t feeling the effects please contact our office for instructions. Or if you experience persistent nausea or vomiting during preparation you should call and let us know.
Health Issues or Medications May Also Impact Prep
This is just one of the many reasons the physicians at CRS may meet with patients beforehand to review your health history and identify and factors that might impact the type of prep given.
It is important to bring a list of every medication you are taking, as there are several different colon preparations and your CRS doctor will determine the best prep based on your specific situation.
If necessary your CRS doctor may consult with your primary care, or GI doctor, to discuss stopping or altering dosage, or certain medications prior to your exam.
Signs Your Colon is Clear
The morning of your exam if you are still passing brown liquid with solid material mixed in, your colon may not be ready and you should contact your doctor’s office.
Passing mostly clear or only a light color, including yellow, is a sign your colon is clean enough for an accurate examination.
