So why do some of us have to be on pre-op diets and others not at all?

A bit confusing, I'm curious to know why doctor's around the world do it differently.

My dr. told me the pre -op diet was to help the liver shrink so they can get to your stomach easier. The stomach is behind the liver,the take like a "metal Straw"& lift the liver up. Why I know this may dr. gave me the pictures of my surgery. I couldn't believe how huge my stomach was,he cut alot off!!!! It was interesting to see!!!!

Each surgeon has their own method. Mine put me on the pre-op diet for nearly a month to shrink my liver down and start the weight loss. I know other people (with different Drs.) that only had to do it for a few days. The surgeons make you do what, in their opinion, works. I spent a while researching doctors and selected the one I have. I'm not going to second-guess someone who I chose because they are one of the best in my geographic area.

On the flip side, my surgeon told me he had gone to a seminar that explained that the liver shrinking was so minimal from the pre op diets, it didn't make much of a difference in size at all. So much to my pleasure and surprise, I had no pre op diet. Just clear liquids the day before and nothing after midnight.

My surgeon told me 1 week of pre-op to shrink liver. Guess she did not go to seminar. But I will do what it takes to get the surgery

Clearly it depends on the surgeon's education, methodology, and the health status of the patient. I'd hope that doctors look at all factors when recommending any diet. Certainly a man with a 40 BMI is going to be treated differently than a woman with a BMI of 65. At least, I hope so...

I thought it may have to do with BMI also, not sure about this
