Gastroscopy is an examination of the upper gut, which is the oesophagus (gullet), the stomach and duodenum (part of the small intestine joining the stomach). The procedure involves passing a narrow flexible instrument through the mouth, into the gullet, and then into the stomach and duodenum to examine the lining.
If you have any recurring symptoms, this treatment can help diagnose various problems and conditions, including:.
Helicobacter Pylori (Bacteria That Causes Ulcers, Gastritis, and Gastric Cancer)
Celiac Disease (Inability to Digest Gluten)
Any Previously Diagnosed Gastrointestinal Conditions
In the procedure room, you will be asked to lie on your left side, after removing false teeth, glasses, and hearing aids. After giving you a mouth guard to prevent you from biting or damaging the instrument and putting a plastic “peg” on your finger to monitor your pulse and oxygen levels, the endoscopist will give you the injection or throat spray.
As the gastroscope goes through your mouth you may gag slightly, this is quite normal and will not interfere with your breathing. During the procedure, you may burp or belch a little due to air entering your stomach. This is also quite normal, but some people find this unpleasant.
A colonoscopy is a test to examine the lining of your bowel, also called the large intestine or colon. The aim is to get a clear view of the lining of your colon. This can help to diagnose your symptoms and check any previously diagnosed bowel conditions. If there are any problems such as inflammation, polyps, or cancer, these will show up in the test.
At the treatment, you will be required to undress and put on a gown and you will be asked to lie on a couch on your left side with your knees bent. If you have sedation, we will give you oxygen through a face mask and put a plastic “peg” on your finger to monitor your pulse and oxygen levels. While the sedative will make you feel relaxed and drowsy, it will not put you to sleep.
The endoscopist will then gently insert the colonoscope through your back passage into your colon. During the procedure, air is passed into your colon to give a clear view of its lining. You may experience some wind-like pains, but they should not last long. You might feel as if you need to go to the toilet. This is a perfectly natural reaction but as the bowel will be empty, there is no need to worry.
