Preparation Instructions for Gastroscopy
NOTHING TO EAT OR DRINK.
No fluids at all for 6 hours before your procedure. (example: if your gastroscopy arrival time is 1PM, you can drink clear fluids only, up until 7:00 AM. If your procedure arrival time is 10:00 AM, you must have nothing at all after 4:00 AM)
Tiny sips of water with your medications is OK.
The "most common mistake"?
Eating solid food for breakfast when you have an afternoon gastroscopy - thinking all you need to do is not have fluids 6 hours before.
