Rate of pre op liver shrinkage
Dear Jennrn2006,
There hasn't been very much comparative research to tell what's the best diet to use to shrink the liver. Optifast 800 calories a day produces about 25% shrinkage in 6 weeks. Even two weeks at 800 calories will be a significant help. You'll, have liver shrinkage because of loss of liver fat an will lose water weight because you won't be eating as much salt.
I try to get patients to lose about 10% of their body weight if they have tight truncal obesity. If they lose about 2 pounds a week, they will have a live with little fat and don't need to use Optifast.
Two days of weight loss won't do much.
There's nothing magic about Optifast. Any low calorie well balanced diet will do fine. It's important that you ask your surgeon what calorie level will be best for you. Active large and tall patient will need more than 800 calories to prevent them from burning their muscle mass.
In summary, I have found that patients benefit greatly from preop weight loss. It seems that their recovery is smoother, their medical problems in better control, and their hospital stay shorter.
Thanks for asking your question,
Dr. Callery
