OGD or Oesophago-gastro Duodenoscopy is a visual examination of the lining of your oesophagus, stomach and duodenum.
You should be on an empty stomach with overnight or 6 to 8 hours of fasting. Post-midnight, you must not consume anything, not even water.
You must inform the doctor about your underlying medical conditions and if you are on blood thinners.
You are settled comfortably in an area where your privacy is respected throughout the procedure. You will be given a hospital gown to change into.
You will have to remove your eye glasses, contact lenses and dentures.
Local anaesthesia is sprayed on your throat to make it numb. You may also be given a sedative by injection.
A mouth guard will be placed to protect your teeth.
While you are in a comfortable position on your left side, the doctor will pass the endoscope through your mouth and throat. You will be asked to swallow the saliva and not the endoscope.
The endoscope will not interfere with your breathing nor cause any pain. This process takes about 5 minutes.
During OGD, if necessary small tissue samples (Biopsies) can be taken during the examination painlessly for pathologic examination
Your throat may feel numb and slightly sore.
Please take rest for one full day.
You should not attempt to eat or drink until your swallowing reflex is normal.
You may return to your regular diet unless otherwise instructed.
You may feel slightly bloated due to the air which has been introduced through the endoscope.
If you have had a sedative injection, a companion must be available to drive you home. For the remainder of the day, you should not drive a car, operate machinery or make important decisions as the sedation impairs your reflexes and judgement.
Upper GI endoscopy is generally a safe procedure although in rare occasions, complications such as cardio-respiratory problems, tear of the intestine or bleeding may occur. Please contact your doctor immediately, in such cases.
