I ate a hamburger 25 hours before my gastric sleeve. Is it safe to have my surgery?

It's important to follow your surgeon’s pre-op instructions, especially regarding diet. Most surgeons require a strict pre-op diet to shrink the liver and reduce surgical risks. Eating a hamburger 25 hours before surgery could pose a risk, depending on your specific instructions.
I strongly recommend that you contact your surgeon immediately and let them know. They will assess whether it’s safe to proceed or if adjustments need to be made.

Hello, I hope you are well. Although it is preferable to follow your pre-operative diet, your surgery would not be cancelled for eating 25 hours prior. Keep in mind however, you should not have anything in your stomach at least 8 hours prior to surgery. In that case, surgery would be cancelled or at least postponed. I hope this answe was useful.

We recommend liquids only 2 days before surgery.  It helps reduce complications during and after surgery.  Your stomach should be completely empty before gastric sleeve surgery.   I hope your surgery went well with no complications.  Make sure you stick to your post operative diet and recommendations for best recovery after surgery.
