Preparing for Gastroscopy


Preparation for the procedure Gastroscopy

An empty stomach is essential for a safe examination, so you should have nothing to eat or drink, including water, for approximately 3-4 hours before the gastroscopy. However, you may have a sip of water with your regular medications. Take your regular medications on the day of the test. We will tell you when to start fasting.

You can continue all your regular medications including aspirin. Let me know if you are diabetic or on anticoagulants (blood thinners) other than aspirin.

Discuss any allergies to medications as well as medical conditions, such as heart or lung disease. Also, alert us if you require antibiotics prior to undergoing dental procedures, because you might need antibiotics prior to upper endoscopy as well.


During the procedure

Your procedure will be done under deep sedation with an anaesthetist. You will lie on your left side for the procedure. The endoscope doesn't interfere with your breathing. You are unlikely to remember anything of the procedure.


After the procedure

You will be monitored until most of the effects of the medication have worn off. Your throat might be a little sore, and you might feel bloated because of the air introduced into your stomach during the test. You will be able to eat after you leave unless we instruct you otherwise.

Because of the sedation given it is very important that you do not drive a car, travel on public transport alone, operate machinery, sign legal documents or drink alcohol on the same day. You must arrange for someone to accompany you home because the sedatives may affect your judgment and reflexes for the rest of the day. You must not drive until the next day.
