How will the Test Feel?
The sedative and pain medication will provide relaxation and produce a drowsy feeling. A rectal examination usually precedes the test to dilate the rectum and make sure there are no major obstructions. You may have the urge to defecate when the rectal exam is performed or as the colonoscope is inserted.
You may feel pressure as the scope moves inside. Brief cramping and gas pains may be experienced as air is inserted or as the scope advances. The passing of gas is necessary and should be expected.
Discomfort may be lessened by taking slow, deep breaths. This will also help relax the abdominal muscles. Mild abdominal cramping and considerable passing of gas may occur after the exam. Medications will produce sedation, which should wear off in a few hours.
