Would it be worth getting re-tested?

[TiredTom111]

I've been using CPAP for almost a year and a half, and almost every night my numbers are pretty good (I've attached a typical night).  I've lost around 15 pounds since I first started treatment, and my original home test showed mild apnea (8 AHI / 15 RDI), although I wasn't obese when I first started CPAP.  Has anyone else had another sleep study done after losing weight and shown any significant improvements in your test results?  It would be nice to be able to "test out" of sleep apnea and not have to deal with the hassles of the machine, although I'm wondering if there would still be noticeable benefit even if my new results were below the threshold for diagnosis...

Home sleep tests are inexpensive and a good screening tool. You can obtain the test equipment from many of the CPAP vendors who will analyze and return results. If you want to know the answers to your question, that might be a good strategy to getting information you want. You were borderline for needing CPAP and while sleep apnea metrics may help make your decision, another reasonable approach is to simply discontinue use and keep a sleep log. If you feel okay, you probably are. Give yourself a trial without CPAP and then make the decision whether you want HST results to back that up. You're not going to hurt yourself. There are plenty of people with a worse problem that never get treatment.
