Which specialist performs colonoscopy?

The gastroenterologist guides a flexible camera through the rectum to view the colon. The test can help investigate bleeding, changes in bowel habit, abdominal symptoms, or findings from other tests. Small growths may be removed and tissue samples may be collected for laboratory examination. A trained endoscopy team monitors you throughout the procedure, and sedation may be discussed beforehand.

Follow the written bowel-preparation instructions carefully, including the timing of the cleansing solution and any temporary changes to food or medicines. Tell the endoscopy unit about diabetes, blood-thinning medicines, allergies, pregnancy, or previous problems with sedation. Arrange an adult to take you home if sedation is planned, because alertness and coordination may be affected afterward.

Mild bloating or a small amount of bleeding after a biopsy can occur, but call the endoscopy team for increasing abdominal pain, persistent vomiting, fever, heavy bleeding, dizziness, or a hard and swollen abdomen. Sudden severe pain or fainting requires urgent assessment.

Ask why the colonoscopy is recommended, whether samples or polyp removal may occur, which medicines need adjustment, and when you should expect the findings and laboratory results.
