What is Gastroscopy？
A gastroscopy is a test where an operator (a doctor or nurse) looks into the upper part of your gut (the upper gastrointestinal tract). The upper gut consists of the oesophagus (gullet), stomach and duodenum. The operator uses an endoscope to look inside your gut. Therefore, the test is sometimes called endoscopy. An endoscope is a thin, flexible telescope. It is about as thick as a little finger. The endoscope is passed through the mouth, into the oesophagus and down towards the stomach and duodenum. The tip of the endoscope contains a light and a tiny video camera so the operator can see inside your gut.
Why Would You Get an Gastroscopy?
Gastroscopy is done to detect lesions in the stomach and duodenum. This include detecting potential presence of harmful bacteria like Helicobacter Pylori. Helicobacter Pylori is a bacteria that resides in the acidic environment of the stomach. It causes gastritis as well as ulceration. Although many infected individuals have no symptoms, other infected individuals may have occasional episodes of belching, bloating, nausea and vomiting and abdominal discomfort. It can also spread from person to person, and is rampant in Asia because of the way food is shared during meals.
You should get instructions from the hospital department before your test. The sort of instructions given commonly include:
You should not eat and drink for at least 8 hours before the examination which means the stomach needs to be empty. Low-fiber food, plain food is recommended 1-2 days before the exam.
If you have a sedative you will need somebody to accompany you home and mustn’t drive on your own.
Advice about medication which may need to be stopped before the test.
You will be asked to sign the consent form for receiving gastroscopy examination or anaesthesia after well understanding with doctor’s explanation.
