Preparing for an Upper G.I. Endoscopy

The upper G.I. tract must be empty before the upper G.I. endoscopy procedure. Generally, no eating or drinking is allowed for 4 to 8 hours before the exam. Smoking and chewing gum are also prohibited during this time.

Patients should tell Dr. Jones 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 or interact with sedatives, which are often given during upper G.I. endoscopy.

Medications and vitamins that may be restricted before and after upper GI endoscopy include

  • Nonsteroidal anti-inflammatory drugs such as aspirin, ibuprofen (Advil), and naproxen (Aleve)
  • Blood thinners
  • Blood pressure medications
  • Diabetes medications
  • Antidepressants
  • Dietary supplements

Driving is not permitted for 12 to 24 hours after upper G.I. endoscopy to allow sedatives time to completely wear off. Before the appointment, patients should make plans for a ride home.
