An endoscopy is usually a safe procedure, and the risk of serious complications is very low.
Possible complications include:
- an infection in a part of the body the endoscope is used to examine this may require treatment with antibiotics
- piercing or tearing (perforation) of an organ, or excessive bleeding you may need surgery to repair tissue or organ damage; sometimes a blood transfusion may also be needed
Sedation
Sedation is usually safe, but it can occasionally cause complications, including:
- feeling or being sick
- a burning sensation at the site of the injection
- saliva or, rarely, small particles of food falling into the lungs, triggering an infection (aspiration pneumonia)
- irregular heartbeat or low blood pressure
- breathing difficulties
When to seek medical help
Contact your GP if you notice any signs of infection in the area where the endoscope was inserted.

- redness, pain or swelling
