Preparing for an Endoscopy Procedure
Depending on what part of your body is being examined, you may be asked to avoid eating and drinking for at least 6 hours prior to the examination.
If you're having a colonoscopy to examine the large intestine or a sigmoidoscopy to examine the rectum and lower part of the bowel you may be given a laxative to help clear stools from your bowels.
The Endoscopy Examination
An endoscopy is a safe and painless procedure and the risk of complications is low.
Endoscopy through the mouth typically involves using local anaesthetic spray to the throat to numb the throat to make it easier to pass the tube. Some patients find that mild sedation can also be useful to help relax
Depending on what investigation is being carried out an endoscopy usually takes around 15-60 minutes. An endoscopy is usually done as a day procedure so you will likely not need to stay in hospital.
If the gullet (oesophagus), stomach or first part of the small intestine needs to be examined, it's known as a gastroscopy. Where the bowel needs to be examined, it's known as a colonoscopy.
Typical Questions People Ask About Endoscopy
What is the procedure for an endoscopy?
Upper endoscopy is a procedure that enables the examiner (usually a gastroenterologist) to examine the oesophagus (swallowing tube), stomach, and duodenum (first portion of small bowel) using a thin, flexible tube called the upper endoscope through which the lining of the oesophagus, stomach, and duodenum can be viewed using a TV monitor.
What is a colonoscopy and endoscopy?
There are two basic types of endoscopy: Upper endoscopy (gastroscopy) – The oesophagus, stomach, and small intestines can be viewed by a thin flexible tube inserted through the mouth. Colonoscopy – The lining of the large intestine, colon and rectum can be viewed by a flexible tube inserted through the rectum.
What does an endoscopy test for?
Endoscopy can help identify inflammation, ulcers, and tumours. Upper endoscopy is more accurate than X-rays for detecting abnormal growths such as cancer and for examining the inside of the upper digestive system. Any abnormalities can also be treated through the endoscope.
Why would you get an endoscopy?
Endoscopy may be used to treat a digestive tract problem. An endoscope can not only diagnose an issue, but devices can be passed through the endoscope that can help treat the condition.
What symptoms would lead to an Upper GI endoscopy?

What conditions can be identified by an endoscopy examination?
Upper GI endoscopy can identify many different diseases including anemia, gastroesophageal reflux disease, ulcers, cancer, inflammation or swelling, precancerous abnormalities, celiac disease
What is an upper GI endoscopy?
An upper gastrointestinal (UGI) endoscopy is a procedure that allows your doctor to look at the inside lining of the oesophagus, the stomach, and the first part of the small intestine (duodenum). A thin, flexible viewing tool called an endoscope (scope) is used.
What is the preparation for an endoscopy?
Typically, a fasting period is required before the endoscopy. You will need to stop drinking and eating four to eight hours before the examination to ensure your stomach is empty for the procedure. Certain medications may also be required to be stopped before the endoscopy procedure.
Can you eat before a gastroscopy and endoscopy?

What happens when you have a camera down your throat?
An endoscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and first part of the small intestine (duodenum). It's also sometimes referred to as an upper gastrointestinal endoscopy. The endoscope has a light and a camera at one end. The camera sends images of the inside of your oesophagus, stomach and duodenum that can be viewed on a monitor by the investigations team.
Is an endoscopy painful?
An endoscopy is a painless procedure, with most people only experiencing some mild discomfort. The procedure is usually carried out while you're conscious. You may be given a local anaesthetic to numb a specific area of the body for ease of insertion of the scope
Are there any risks in an Endoscopy Examination?
An endoscopy is a very safe procedure. Rare complications include: Bleeding. Your risk of bleeding complications after an endoscopy is increased if the procedure involves removing a piece of tissue for testing (biopsy) or treating a digestive system problem.
How long does it take to get a gastroscopy?
An upper endoscopy takes approximately 10 to 15 minutes. A colonoscopy takes approximately 15 to 30 minutes.
How long does it take to recover from an endoscopy?
Patients typically remain in the recovery area for 30 to 40 minutes after their procedure.
