Gastroscopy prep, made simple and calm.
A clear, step-by-step guide that walks you through every stage of gastroscopy preparation — from fasting times to reminders, so nothing is left to guesswork.
Prep checklist
A day-by-day checklist from 7 days before through the morning of your procedure.
Diet guide
Clear lists of what to eat, what to avoid, and when to switch to clear liquids.
Reminders & tracking
Set gentle reminders for your fasting times, hydration and admission so you stay on track.
Procedure info
Know exactly what happens before, during, and after your gastroscopy.
Eating and fasting guide
A gastroscopy needs an empty stomach, not a bowel cleanout. Eat normally until your fasting window begins.
Eat as normal
No special diet is needed in the days before your gastroscopy.
- Keep taking your usual medicines unless told otherwise
- Avoid alcohol the night before
Fasting window
Counted back from your admission time, not the procedure time.
- Morning admission: nothing to eat from midnight
- Afternoon admission: light breakfast finished by 7:00am
- Water only until 2 hours before admission
- Nothing at all in the last 2 hours
Weight-loss injectables
Ozempic, Wegovy, Mounjaro and similar medicines slow stomach emptying.
- Tell the clinic at least 7 days before
- A clear-liquid day is usually needed
- Never stop an injection on your own
- Call 08 6389 0631 to confirm your plan

Before arrival
You will have followed the prep checklist and clear-liquid diet. Arrive on time with your Medicare Card, Health Insurance Details, a current medication list, and a ride home.
During the exam
You will receive sedation to keep you comfortable. The procedure typically takes 20–30 minutes, and you will rest briefly afterward.
After care
You will need a ride home. Most people resume normal activities the next day. Your doctor will share results and follow-up plans.
Please read these instructions carefully and follow your prep instructions as detailed
