The upper GI tract must be empty before upper GI endoscopy. Generally, no eating or drinking is allowed for 4 to 8 hours before the procedure.
Patients should tell their doctor about all health conditions they have especially heart and lung problems, diabetes, and allergies and all medications they are taking. Patients may be asked to temporarily stop taking medications that affect blood clotting.
Medications that may be restricted before and after upper GI endoscopy include:
- blood thinners
- diabetes medications
Driving is not permitted for 12 after upper GI endoscopy to allow sedatives time to completely wear off. Before the appointment, patients should make plans for a ride home.
