Aftereffects of a Colonoscopy Procedure

A colonoscopy is a diagnostic tool for detecting colon cancer and other conditions. A long, flexible tube with a camera is inserted into the rectum and fed through the colon to look for abnormalities. This procedure is performed basically the same way regardless of age or gender. However, the aftereffects of a colonoscopy procedure may differ slightly from person to person, depending on general health, pain tolerance, and whether or not tissue samples were taken or polyps removed.

Motor Impairment

• The sedation and pain medication may inhibit motor coordination, so driving and operating machinery is prohibited for 24 hours.

Gas

• Air passes through the colonoscope, filling the colon to provide the best view; however, this air may cause minor bloating or gas for a few hours afterward.

Cramping and Light Bleeding

• Mild cramping and light bleeding may occur due irritation of the rectum and anus from the colonoscope, tissue sampling or polyp removal.

Diet and Elimination Issues

• Fasting and bowel cleansing before the procedure may require that patients follow a light diet afterward to avoid stomach distress; bowel movements may be slightly abnormal for a day or two.

Rare Side Effects

• Fever, severe stomach pain, chills, heavy rectal bleeding, bloody bowel movements and vomiting are atypical side effects that may occur after the procedure due to rare colon perforation.
