A colonoscopy involves the use
of a colonoscope—a long, thin,
flexible instrument connected
to a camera and video display
monitor. With the patient lying
on his/her side, the physician
inserts the colonoscope into
the rectum and moves it through
the entire colon. If the physician
notices anything of concern during
your colonoscopy, he/she may
perform a biopsy (removing a
small amount of tissue to examine).
A colonoscopy makes it possible
to find and remove abnormal tissue
growths (polyps) without surgery.

usually takes less than an hour.
Mild sedation is typically provided
to relieve anxiety and discomfort.
For this reason, you will need
to bring a responsible adult
with you to accompany you home
after the procedure. You should
not drive or operate machinery
for at least 8 hours after the
procedure. The sedation given
during the procedure causes drowsiness,
dizziness and impairs your judgment,
making it unsafe for you to drive
or operate machinery.
Following the colonoscopy, you
may experience bloating, which
will quickly dissipate. Most
patients can resume eating a
regular diet later the same day.
