I Accidentally Ate or Drank Before Surgery
Enter what you had and when. This tells you whether it's likely fine, or whether you need to call your surgical team before you go in.
We measure the gap to your hospital arrival time (not the exact start of anesthesia), which builds in a safety margin.
Frequently asked questions
I ate before surgery — what happens now?
Don't panic, and don't hide it. Tell your surgical team exactly what you ate and when. Depending on how much, how long before surgery, and your health, they may proceed, delay, or take extra precautions. Eating a full meal close to surgery usually means it is postponed for safety.
I drank water 3 hours before surgery — is that OK?
Often yes. Clear liquids like water are usually allowed up to 2 hours before your hospital arrival time, so 3 hours before is typically fine — but confirm with your team, especially if you have reflux, diabetes, or take a GLP-1 medicine.
I drank juice or milk before surgery — is that a problem?
Milk and juice with pulp are treated like food (about a 6-hour window), not clear liquids. If you had them inside that window, call your team — they may need to delay or take precautions.
Should I hide that I ate before surgery?
Never. Hiding it is dangerous — food in your stomach can be breathed into your lungs under anesthesia (aspiration). Your team would much rather reschedule than risk your safety.
