Why a sleep study?

I was dx'd with severe obstructive SA in 2007 and put on a BiPAP.  Fast forward to August 2015...I started the 3 mos of pre-op supervised weight loss classes/diet that my insurance required.  A few days after starting I had my yearly followup with my sleep doctor.  She told me that once I lost 20lbs to bring in my BiPAP to have it converted over to an Auto BiPAP.  It automatically adjusts to the settings I require. 

I have now lost 85lbs. and am no longer super morbidly obese (now just obese), but I still have SOSA.  My doctor did say that some patients do not stop having SA and that I may fall into this category.  We shall see...

I didn't have to do a sleep study.

EXACTLY! So I don't get why some require it and some don't. People seem to be getting pissy with me, but in my suspicious head I'm thinking they are maybe promoting their sleep center is all. I could be wrong. And getting the test isn't a big deal, it's just that i feel the need to understand everything

I had to have a sleep study done as well. I didn't really ask why, I just figured it was part of the process. My primary Dr. let me do a in home sleep study. I did it for three nights and took it back to the Dr. office. It wasn't bad at all. It did take a while to get the results back. I do have (and I figured I did) sleep apnea and now have a CPAP machine. I feel more rested now than I have in a very long time.

I did not have to have a sleep test before surgery.  I was told it wasn't required because I have been closely monitored by my sleep doctor and had just had my yearly followup only 4 months before (my surgery).

I i have sever sleep apnea i stop breathing over 200 times a night the dr said i barely sleep in the night i spend most of my time trying to breath and he was right i would wake up min 7 times max 10 times ever night to go pee come to find out  thats a symptom i was prescribed a APAP machine no word of a lie ever since i started using it i do not wake up in the night and i sleep right thru and feel more rested 

I consider my auto BiPAP my best friend (and life saver).

I think my surgeon is the one that requires a sleep study, not my insurance company. On the "new patient" form I had to fill out before I attended my first meeting, I had to list who in my family has or had sleep apnea. My dad has it, so I think that is why my surgeon wants a study done so that I can find out if I have it or not.

I had already been diagnosed with sleep apnea prior to WLS, since my doctor could provide the information on my diagnosis i did not have to have another study done. It is for the safety of your health. I would not have been allowed my surgery if i hadn't of taken my CPAP with me to the hospital. 

You would be best to follow your doctors orders as it just might save your life if you have sleep apnea and get diagnosed prior to surgery otherwise if you have un diagnosed sleep apnea it could be life threatening at surgery time.

I'm getting that idea from reading these posts, but I don't understand. Don't they intubate you during surgery? If so, don't they breathe for you? Maybe I'm wrong. I'll have to do a little research.
