I took the at home Sleep Apnea test and now I'm told I have moderate Seep Apnea. I have to go into a sleep study center for treatment? Does anyone know if this will cause a postponement of my surgery? I actually do not have a problem sleeping and am truly adverse to wearing a mask on my face every night. Is anyone aware of any other treatment or workaround in place of that mask or even any timeframe of how long the treatment takes? Any advice or comment is greatly appreciated. Thanks in advance.

Cigna again denied my overnight sleep study. They said they will approve an Apap machine if my doctor request it. Does anyone know how long that treatment last? Thanks in advance.

It is basically a variation of a cpap.
You will wear it for life unless you lose enough weight that you no longer have sleep apnea.

I can't see me wearing that thing for life. I'm just wondering how long I have to wear it before I can proceed with surgery.

Ask your doctor. Sleep apnea isn't something you treat and then it gets better. It's something you live with.
