When do you qualify for colonoscopy on nhs?

In the UK, you typically qualify for a colonoscopy on the NHS if you are over 50 and experiencing symptoms such as rectal bleeding, a change in bowel habits, or unexplained weight loss. Additionally, individuals under 50 may qualify if they have a family history of bowel cancer or have specific symptoms that warrant further investigation. Referral by a general practitioner (GP) is usually required to access this service.
