Pre-Surgery Weight Loss

 I'm going to try to get hold of my surgeon's nurse to clarify but I thought ya'll could probably give just as good a reply.  I have a BMI of 42 and currently no co-morbidities.  I think once I have my sleep study we'll find I have apnea but for now lets say I have none.  I can only lose around 13 lbs or I'll drop to a BMI of 39.  Now my Dr. said he's not going to penalize me for losing weight and he doesn't care if I drop 30 lbs before I'll still qualify because of my starting weight.  BUT he didn't say when that starting weight was.  That day?  The first day I meet with the NUT?  I don't meet with my NUT for another 2 weeks but I wanted to start getting on track now, but I don't want to lose weight now and 1) not have it count towards the 10 I must lose before the surgery or 2) keep my from having surgery because I'm now too low a BMI.

So any help would be appreciated.  Thanks!  Hope that makes some sort of sense.

For me the first weigh in is my "initail weight" but you may want to call to be sure. Good Luck!
