Your doctor may recommend a colonoscopy if you are experiencing symptoms such as changes in bowel habits, constipation, diarrhoea, bleeding from the back passage, anal discharge, bowel incontinence, or an itchy anus. It can also help diagnose bowel cancer and monitor conditions such as Crohn’s disease.
During the procedure, your doctor may take biopsies (small tissue samples) from the lining of the colon for laboratory testing. Polyps can also be removed at the same time. Although polyps are usually harmless, some can develop into cancer over time.
Depending on your symptoms, alternative investigations may include a sigmoidoscopy, virtual colonoscopy, or barium enema.

A colonoscopy is usually performed as a day-case or outpatient procedure, so you will be able to go home the same day. After the examination, you will rest in recovery for a short time while any sedation wears off, and you may feel drowsy.
It is normal to experience mild bloating or wind-like discomfort, which usually settles quickly. If sedation or biopsies are involved, you may feel tired or notice a small amount of bleeding.
You will need someone to take you home and stay with you for the first 24 hours if you have had sedation, as you will not be able to drive.
Results from any biopsies are usually available within a few days and sent to your referring doctor.
Complications are rare, but you should seek urgent medical advice if you experience severe abdominal pain, heavy rectal bleeding, or fever.
