So I’m scheduled to get the surgery this week and yesterday I ate a full meal and today I ate a pastry and 3 chips with salsa. I’m not going to eat again I have 3 1/2 days until the gastric sleeve surgery. I tried not to but got super hungry. Will they cancel? Will they know that I cheated on my pre op diet.? Please help.

this seems to vary greatly from reading the posts here. My surgeon cared little for the pre diet that most seem to mention here and cared only about the last 48 hours so i would be cleaned out. I had no issues with surgery so nothing important must have been still in there. That said i have seen post about surgerys being canceled because of pre op diet issues so this one is going to be about your particular surgeon.

Sorry could give you a better answer than that

Better pray your liver is nice and lean, surgeries have been canceled because it was too fat to be moved out of the way. You don't want to wake up the same way you went in. That would mean all your preparations were worth nothing.

I agree with the first post. My surgeon cared little for the pre-op diet as my BMI was around 40 and as long as I was cleaned out the last two days (all clear liquids) I think it would have been fine. I did follow the rules for the 1 week diet pretty strictly but no one even asked me the morning of the surgery how it went. Only if i has had any food or drink in the past 12 hours. Keep it clean until surgery- no more cheating and be honest the morning of. They will most likely keep it on if you are good from here on out. No guarantees though. But if they cancel it’s because there is good reason.

I ate a normal meal the night before the surgery, went off the diet for a full 36 hours starting 5 days before the surgery, and cheated here and there. I lost a total of 10 pounds on the pre-op diet, but had gained 10 between my last surgery-related appointment, so in their eyes, I didn’t lose a pound. They performed the surgery and it went off without a hitch, but I was fully prepared for them to not do it, and if they hadn’t, it would have been 100% my fault.

My surgeon told me patients have told him that the pre-surgery diet is the hardest part of the process, and he’s absolutely right. You’ll have much stronger deterrents to eating poorly down the road.

Thanks for all the help.
