full face mask after surgery?

I've seen some concern that after surgery there is a possibility of there being a problem with swallowing air from CPAP machines.  I'm wondering if anyone who uses a full mask before surgery had to or was told to change to a mask just over the nose afterwards?  Or is it really not something to worry about?

What matters most is not what others have encountered, but what your doctors recommend for your particular cir****tances. Be sure your surgeon, anethesiologist and the doctor treating your apnea are all aware of your condition and the CPAP machine you use so they can recomment any necessary adjustments. Ask the surgeon and doctor very specifically if you need to modify your mask or settings so you can have your machine ready when you get home from the hospital.

The things I've seen on line on this subject seem to be merely speculation about the machine blowing air into your stomach and endangering the stomach staples. Who breathes through their stomach??   I'm not a doctor, but the air seems to go into my lungs, not my stomach!  I use the nasal pillows type of mask and had no changes post op. As my weight loss progresses, I'm told I will have another sleep study to determine if I need to continue using CPAP.

I cannot seem to use the nasal mask and have always used the full face mask, which I took with me to the hospital for after surgery.  Coming home I did realize that I breathe through my mouth when I sleep and that provided some major discomfort when I'd get a bunch of air into my stomach pouch.  After retraining myself on how to just breathe through my nose or in through the nose out through the mouth I'm doing just fine. Talk to your surgeon and between the two of you you'll figure it out.
