What is it?
A gastroscopy, also called upper gastrointestinal endoscopy, is an endoscopic exam used to investigate the upper GI tract i.e. the oesophagus, stomach and duodenum (the upper part of the small intestine).
It is used to investigate digestive symptoms of the upper digestive track, and can also detect the presence of Helicobacter Pylori infection.
Our doctor will give you specific instructions to prepare for your exam. Those may include fasting for at least six hours before the exam, and stop taking certain blood-thinning medications as well as other medications that affect the result of Helicobacter Pylori tests. You should tell your doctor about all medication and supplements you are taking as well as if you are pregnant or have a pacemaker.
During and after the procedure
A sedative will be administered to help you relax and minimise discomfort. Your doctor will then insert the flexible endoscope in your mouth down the oesophagus, stomach and duodenum. A gastroscopy typically takes around 30 minutes.
After the procedure, you will recover from the sedative in the recovery area where the medical staff will keep monitoring you. The effect of the sedative takes time to disappear, so you should not drive, operate heavy machinery or sign legal documents on that day. Also avoid hot foods or drinks for at least 2 hours after the procedure.
