Gastroenterology / Endoscopy


Colonoscopy is a test that allows your doctor to look at the inner lining of your large intestine (rectum and colon). He or she uses a thin, flexible tube called a colonoscope to look at the colon. A colonoscopy is usually performed to investigate any recent changes in bowel habits, bleeding from the rectum (back passage), abdominal pain or prolonged diarrhoea, and to screen for early signs of bowel cancer. It is done to make or confirm a diagnosis. 

You will usually be given a preparation kit with full instructions. This usually means having a special diet for a couple of days, and nothing but clear fluids for 24 hours before the test and taking a bowel preparation (laxative medication that causes diarrhoea and empties the colon), depending on your medical condition, the doctor will recommend the right one for you. 


Gastroscopy (or endoscopy) is an examination of the oesophagus (gullet or food pipe), stomach and duodenum (upper part of the small bowel) using a flexible telescope called a gastroscope. A gastroscopy is usually done to investigate the cause of abdominal pain, vomiting or bleeding from the digestive tract, and to make or confirm a diagnosis. Conditions can also sometimes also be treated via gastroscopy — for example, polyps can be removed.
