Fasting Before Day-Care Surgery
Day-care (ambulatory) surgery means you go home the same day — but the fasting rules are exactly the same as for an overnight stay.

Fasting for this procedure
Stop solid food and milk about 8 hours before, a light meal about 6 hours before, and clear liquids about 2 hours before your hospital arrival time. Going home the same day does not change the fasting rules.

Medicines to check
- Blood thinners (aspirin, clopidogrel, warfarin, Eliquis, Xarelto) — see medications to stop.
- Diabetes medicines & insulin — they need a plan. See diabetes tablets.
- GLP-1 (Ozempic, Wegovy, Mounjaro) — tell your team. See the GLP-1 guide.
- Blood pressure medicines — confirm which to take with a sip of water and which to hold.
When this surgery may be delayed
- Fever, a new cough/cold, or a chest infection
- Vomiting or diarrhea
- Very high blood pressure or blood sugar
- You ate or drank outside your fasting window
- You have no responsible adult to take you home
Reports & documents to carry
- Photo ID and insurance card
- A written list of all your medicines and doses
- Any blood tests, ECG, or scans your team asked for
- Consent forms or referral letters, and allergy details
- A responsible adult to drive you home and stay overnight
- Comfortable, loose clothing to go home in
What to ask your anesthesia team
- Will I have general anesthesia, spinal/regional, or sedation?
- Which medicines do I take or hold on the morning of surgery?
- When can I eat and drink afterward?
- Will I go home the same day, and who can drive me?
- How long after surgery before I can be discharged?

Frequently asked questions
Do I still fast for day-care surgery?
Yes — fasting is the same as for any surgery: solids stop about 8 hours before and clear liquids about 2 hours before your hospital arrival time. Going home the same day doesn't change this.
Can I drive myself home after day-care surgery?
No. After anesthesia or sedation you can't drive, and most centers won't discharge you without a responsible adult to take you home and ideally stay the first night.
