Know why the test is proposed
Gastroscopy examines the upper digestive tract, while colonoscopy examines the large bowel. Ask what question the procedure aims to answer, whether biopsies or treatment may occur, important risks, alternatives and how results will be provided. Consent can be revisited before the procedure.
Follow your own preparation instructions
Preparation differs by procedure. Colonoscopy usually requires bowel preparation; incorrect timing or incomplete preparation can limit the view. Tell the team about blood thinners, diabetes medicines, allergies, kidney or heart problems, pregnancy possibility and previous sedation problems. Do not stop medicine unless instructed.
If sedation is planned, confirm fasting, transport, adult supervision and restrictions on driving, alcohol, legal decisions or machinery. These instructions may continue after discharge.
After the procedure
Mild temporary bloating or throat discomfort can occur, but follow the discharge information for your exact procedure. Ask whether samples were taken, when results are expected and who will discuss them.
