Understanding Colonoscopy
A colonoscopy is a medical procedure used to examine the inner lining of the large intestine (colon and rectum). It is an essential tool for detecting colorectal cancer, polyps, ulcers, and other gastrointestinal abnormalities. The test uses a long, flexible tube equipped with a tiny camera, allowing doctors to view the colon in real-time and, if necessary, take biopsies or remove growths.
What is a Colonoscopy?
During a colonoscopy:
A flexible tube called a colonoscope is inserted through the rectum.
The camera transmits images to a monitor, allowing the specialist to examine the colon lining.
Polyps or abnormal tissues may be removed or biopsied during the procedure.
The test typically lasts 30–60 minutes, often under sedation.
A bowel preparation is required beforehand to clear the colon for a clear view.
Colonoscopy is both a diagnostic and preventive procedure, playing a key role in bowel cancer screening programmes.
What to Expect from a Colonoscopy Service
When accessing a colonoscopy service, you can expect:
A pre-procedure consultation with a gastroenterologist or nurse specialist
Instructions for bowel preparation, often involving laxatives the day before
The procedure to be conducted in a clinical, sterile environment, often with sedation
Recovery time of 1–2 hours before being discharged
A full report of findings, sometimes with same-day feedback
Most patients return to normal activities by the following day.
