An endoscopy does not require an overnight stay in the hospital and usually only takes around 1 hour to complete. The doctor will provide instructions about the preparation for the procedure.

For many types of endoscopy, the individual needs to fast for around 12 hours, though this varies based on the type.

For procedures investigating the gut, laxatives may be taken the night before to clear the system.

A doctor will conduct an examination before the endoscopy. It is important to mention all current medications (including supplements) and any previous procedures.
