I was diagnosed with OSA almost a whole year ago and was put on a CPAP for regular use. It has helped me a ton and I was able to sleep through the night just fine. I'm a 22 year old female.
More recently, within the last few weeks, I found myself waking up several times a night - usually every 2 to 4 hours. Sometimes I stay up and it's difficult to go back to sleep, interrupting my sleep schedule and thus causing me to be tired throughout the day. The first thing that came to mind was that the air pressure on my CPAP may be less effective..I'm a tiny, petite little lady so my settings are on 8.0 mmHg. Naturally, I use my CPAP every night.
Not sure if this is a factor but I've managed some weight loss, around 20lb since then as well, so I haven't gained any weight. I have an appointment with my doctor in about a week. Anyone have similar issues?
