Endoscopy, in particular gastroscopy and colonoscopy, involves the visualization of the stomach and bowel using fibreoptic or television microchip devices. It allows doctors to look carefully at the inside surfaces of these structures and where appropriate take photographs, in order to diagnose abnormalities and/or disease.

Safety and Risks
• The instruments are completely cleaned and disinfected between each patient so there is no risk of transmission of infectious diseases
• The most common complication of gastroscopy are mild throat soreness ,abdominal bloating and discomfort
• The most common complication of colonoscopy is intolerance to the bowel preparation , soreness around the anus , and bloating and discomfort after the procedure.
• More serious complications are rare and include perforation (puncture) to the stomach , oesophagus or bowel wall,or reactions to the sedative drugs.These problems may require urgent treatment or surgery.
• While these procedures are the most accurate means of assessing the gastro intestinal tract, it is possible to miss small lesions
• You may not be aware of complications until a few days ate the procedure.
Any bleeding or severe pain should be reported to the doctor promptly
• Like all invasive medical procedures there is a remote chance that complications can result in death,although this is extremely rare.
