I have been on a CPAP for the last year, with a low pressure of 9. However, even with this low pressure, I have had some serious problems which I think are GI related. I had been taking Prevacid to clear up an issue with my stomach and had completed the meds and was doing great. Went off the meds. Then a couple months later my CPAP started filling me up with air to the point I looked pregnant. Lots of gas, belching, and stomach pain.

This caused me to start having nausea and to have to go back on the medicine for my stomach. I have had constant nausea for two months. I went to the sleep doctor and had a new sleep study done. Then went back for titration to set me up on a BiPap S/T. Now the pressure is going to be 112/8 with a back up of 10. Turns out 88% of my apnea is Central and only 12% Obstructive, that's why they are putting me on BiPap.

Now during all this, I have been feeling really bad. Last Thursday I went to the emergency room because of tightness in my chest. By the time I got there, my blood pressure was 164/114. All the tests came back fine that it wasn't my heart. So did the stress test done 10 months ago. So, again, I am thinking it has to be GI related and due to the pressure and air going into my stomach.

My concern is, if I was at a 9 pressure before on CPAP and now I am going to be on a 12/8 pressure on BiPap, will this make my problem worse? I've asked the people in the lab and they assure me that BiPap is so much different that it should be better, and they are willing to adjust the pressure in a couple of weeks after I get my machine if I am having problems. I just would like some input from anyone who has gone through this. Will it be better?
