Stomach air?

This past week I've started getting air pushed into my stomach. I don't know what's changing but it's really miserable.

Has anyone experienced this as they've lost weight? I'm wondering if my pressure is too high now that my weight is down over 50 lbs (I'm at 155lbs now).

I was hoping to delay having another sleep study until I've gotten closer to my goal weight...

I started APAP about 3 weeks ago but have been sick and breathing different this week and couldnt use it it for the last few days. Last night however it statered doing that me to me. I wonder if your weightloss with a constant pressure value no longer fits your more agile airway if you will. I would see your RT and have them review your numbers. Goodluck

Never had such issues, but I've heard about them...
