mandmom 31 Posted March 3, 2019 What is the purpose of these shakes? I've lost enough weight pre-op to have a BMI of 37 so my liver is not big. Why do some drs want this and others just say nothing after midnight night before surgery? Share this post Link to post Share on other sites
lesslana 6 Posted March 3, 2019 Actually having a low BMI isn't an indicator of liver size from my understanding. Everyone in my program does 2 week regardless of BMI. Share this post Link to post Share on other sites
DanaC84 1,116 Posted March 3, 2019 I can’t speak for all drs but mine told me it was to shrink the size of my liver for easier access to my stomach during surgery. Share this post Link to post Share on other sites
Avery's Mom 315 Posted March 4, 2019 overall BMI does not correspond to fatty liver necessarily. basically it is a precaution to ensure they have as much room to operate as they can Share this post Link to post Share on other sites
