When is colonoscopy needed?

Diagnostic colonoscopy investigates symptoms, anemia or abnormal tests. Screening concerns people without symptoms according to age, risk and local programmes. New symptoms may need assessment before routine screening age.

Investigation or screening?

Diagnostic colonoscopy investigates symptoms, anemia or abnormal tests. Screening concerns people without symptoms according to age, risk and local programmes. New symptoms may need assessment before routine screening age.

Does every bleeding episode require full colonoscopy?

No. Examination, age, family history, persistence, associated symptoms and previous tests guide the choice. Finding hemorrhoids does not remove the need when they fail to explain the overall picture.

What should preparation cover?

Ask about bowel cleansing, diabetes, blood thinners, an escort after sedation and biopsy results. Follow the centre’s instructions rather than someone else’s regimen. Poor preparation may reduce accuracy and require repeat testing.

Optional AI assessment sends your answers and text to Cloudflare only with your consent; files are sent when you request extraction. Remove identifiers before upload. The app creates no permanent medical record and no clinician reviews the output. Answers do not persist after reload and are not sent automatically to the clinician. WhatsApp is an external service; the booking button does not attach medical answers. Saved or copied reports contain health information: review them and choose who to share them with.
