I begin my pre-op diet tomorrow. I am looking forward to the journey. My surgery is August 1st so my pre-op diet is one week. I notice that many people have 2+ weeks of pre-op diet. Why the variation? Any insight? I'm just curious.

The liquid diet(from what I have read/heard) is to shrink the liver & fat around the stomache to make surgery easier/safer. My surgeon said it depends on your BMI how long you have to be on pre-op diet. Makes sense to me I guess...The higher the bmi the more fat that is around the stomache to interfere with the procedure...

not sure... mine was 2 weeks before and 2 weeks after.

i guess that decision is up to each individual surgeon.

Pre-op diets vary by surgeon based on their experiences and the patient's medical needs/history. Same with post-op diet phases.

Mine is two weeks, I got a call today they have am opening one week earlier o I start mine tomorrow!!

very interesting... my pre-op liquid diet was one day. Tuesday liquids, Wednesday surgery. My bmi is 40. I see you got your surgery on the 1st, so did I!

My BMI was 36 when I started my Pre-op diet, clear liquid only with 3 shakes a day. I was down under a 35 BMI yesterday for my surgery. My Pre-op diet was 5 days.
