Upper GI endoscopy can be used to remove stuck objects, including food, and to treat conditions such as bleeding ulcers. It can also be used to biopsy tissue in the upper GI tract. During a biopsy, a small piece of tissue is removed for later examination with a microscope.

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. Smoking and chewing gum are also prohibited during this time. 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 or interact with sedatives, which are often given during upper GI 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 GI endoscopy to allow sedatives time to completely wear off. Before the appointment, patients should make plans for a ride home.
