I'm pre-op for gastric sleeve surgery. I will have all of my clearances completed (only psych and 2 NUTs required for me) at the very end of May.

Here's my question...neither my insurance nor my surgeon require any sort of pre-op diet. My advocate said it's easier on the surgeon if we don't go pigging out and gain a bunch of weight, but specifically said there's not a diet.

How do I/they know that my liver isn't enlarged and won't present a problem during surgery? I know he's doing it robotically--does that make a difference?

I've lost 7lbs on my own since March just trying to eat better.

I weigh 317lbs and have a high BMI. Just wondering if anyone else had no diet required and if it made any difference?

I did not have a pre-op diet, but was not allowed to gain anything or they would cancel surgery (I lost 6 lbs.).

Lots of people have no pre-op diet required. I would guess your surgeon is very experienced and knows what works best for him or her. If you don't trust your surgeon to decide about a pre-op diet, maybe this isn't the right surgeon for you?

I trust my surgeon. That's a big conclusion to jump to.

With the awesome info and experiences you find on this board, you also find horror stories that can be scary. I just finished reading through a thread about canceled surgeries because of large livers--and they'd already made the incisions and had to back out. There were several and I was just curious as to whether its technique, experience, or luck of the draw that determines liver size and how it affects operations.
