How can I help?

A gastroscopy is a test that allows doctors to investigate the oesophagus and the duodenum (this is the upper portion of the small intestine). A gastroscopy is carried out using a small flexible tube known as a gastroscope.

The test is very quick, usually lasting only 5 minutes. However, you may be advised to stay in the hospital for 2-3 hours after the procedure. It is essential that you avoid eating or drinking anything for at least six hours beforehand so that doctors can view the stomach clearly.

The Procedure

A gastroscopy can be performed using local anaesthetic alone or with sedatives, which are administered intravenously. Some patients may choose to be sedated because it eliminates discomfort.

Most patients opt for gentle sedation to make the procedure more comfortable and a team of anaesthetists is available for all gastroscopy procedures carried out at OneWellbeck. A general anaesthetic is more comfortable than a local one. However, local anaesthetics allow you to recover very quickly and resume normal activities straight away. You will also be able to talk to your doctor about the findings of the test immediately.


You should be able to drink and eat after around 30 minutes, but you may experience bloating for a few hours afterwards due to the air pumped in during the test.

If you were sedated, you may feel drowsy, so it’s important that a friend or relative is available to take you home and stay with you for the rest of the day. You should avoid driving or operating machinery for 24 hours afterwards and should also refrain from alcohol.
