I was diagnosed with Obstructive Sleep Apnea and received my APAP machine this past April. I was able to use it for 3 nights before I developed AWFUL bloating and stomach pain. I continued to use it but found I could only tolerate it 4 hours a night. And it took me all the next day to feel better and lose the bloat.
I made an appt. with my Dr. and he didn't understand why that is happening. He says my pressure is fine (I wanted him to turn it down) and the machine is automatic so it should react to my inhaling and exhaling. Anyway, I researched online and found it has a name - Aerophagia. At least I knew at that point it wasn't just me. I requested nasal pillows hoping that would help, since I had been using a full face mask. Didn't help, in fact the nasal pillows were worse and very uncomfortable. I was given every size they have of the pillows so it wasn't the size. My Dr. had a woman from the sleep place call me and tell me it was basically "common sense" as to how to handle my problem. (I had a few words for her.) So, right now the only thing I can do is block off the lower part of my full face mask with duct tape, of all things, so the air doesn't get in my mouth, just through my nose. That worked for about 2 nights and I bloat up again. I prop my pillow up, position my neck properly,take Gas-X, etc. and nothing helps. Does anyone else have this problem and/or am I just intolerant to using these machines?
