How long will I need to fast before surgery?
The usual fasting time is 6 hours before surgery. This includes all liquids as well as solids (though prescribed medications should be taken with a sip of water at their usual time).
Diabetic medications should be specifically discussed with your doctor as they may need to be adjusted at the time of surgery.
Usually if your surgery is in the morning then you will need to fast from midnight the previous night. If your surgery is definitely in the afternoon then you may be allowed an early light breakfast, though check first as operating list ordering may change at short notice.
