OGD (Gastroscopy)

What is OGD?

It is the first line investigation for symptoms arising from the upper digestive tract. The presence of Helicobacter Pylori infection can also be detected with this examination.

How should you prepare for OGD?

You should keep fast for at least 6 hours before the examination. Your physician needs to know all the medications that you are taking. Certain blood thinners might have to be stopped one week before. Antibiotics and proton-pump inhibitors such as Nexium® may affect the result of Helicobacter Pylori testing, and should be avoided for four weeks before the examination.

What will happen during and after OGD?

You will receive medications to put you to sleep and ease any discomfort during the examination. The physician will then put a flexible endoscope through your mouth into the esophagus, stomach and duodenum. The whole procedure usually lasts about 10 to 15 minutes.

After the procedure you will wake up, but still feel sleepy. Please take rest in the recovery area until you have regained full strength. You should not drive, operate heavy machinery, perform hazardous activities or sign legal documents on the day of examination as the drug effect takes time to completely wear off.

The feelings at your throat may not return immediately after the examination. Please do not have hot foods or drinks for at least 2 hours after the examination to avoid scalding.
