Tissue removal and treatments to stop bleeding do not usually cause pain.
A colonoscopy often provides the means for accurate diagnosis and treatment of colon abnormalities without the need for a major operation. Complications of a colonoscopy, such as bleeding and puncture of the colon, are possible but this would be uncommon.
A colonoscopy usually takes between 30 and 60 minutes.
You may have mild cramping or the sensation of 'gas' after the procedure, although this is usually over within an hour.
You will need to stay at the colonoscopy facility for one to 2 hours in order for the sedative to wear off, and then have someone else drive you home.
Rarely, some people experience severe abdominal pain, fever, bloody bowel movements, dizziness, or weakness afterward. If you experience any of these side-effects, contact your doctor immediately.
It is important to read your discharge instructions carefully; for instance, medications such as blood-thinners may need to be stopped for a short time.
Normally, you will be fully recovered by the next day and you may return to your regular activities.
