Hi There, Although I personally haven't had my surgery yet, I do have mild OSA and expect it to clear up once I lose the weight. I work as a nurse/sleep therapist and perform sleep Studies and CPAP therapy. I had a patient who was 300 lbs and dx with severe sleep apnea stopping breathing 30 times an hr. He didn't want to wear a CPAP so he decided to lose the weight. Lost 70 lbs and was retested and now does not have sleep apnea. Good Luck!
