Colonoscopy is an endoscopic examination in which the large intestine and rectum are examined using a flexible tube (endoscope) and a camera. It is used to investigate bowel complaints and symptoms and for the early detection of bowel cancer.
Colonoscopy is usually performed in cases of unexplained abdominal pain, weight loss, persistent diarrhoea or constipation, blood in the stool and anaemia. A colonoscopy may also be recommended for patients with an increased risk of bowel cancer, for example due to a family history.
There are different recommendations regarding the ideal examination interval. In general, a first colonoscopy is recommended between the ages of 50 and 55. If no polyps are found, the next examination should usually take place after 10 years. However, if polyps are found, the interval is shortened accordingly to avoid an increased risk of cancer.
The duration of the examination depends on various factors, such as the condition of the bowel and any findings. As a rule, a colonoscopy takes between 30 and 60 minutes.
It is important to emphasise that colonoscopy is an important examination for the early detection of bowel cancer and should be performed when indicated. Talk to your doctor about your individual risk profile and the optimal examination strategy.
