How much weight loss before new sleep study?

Presuming you are starting from a non-ideal weight (let's say obese on the BMI scale; leaving aside for the moment the relevance of the BMI scale to any one individual), and you lose weight - at what point would you wonder whether a new sleep study was warranted and/or wonder whether your settings would need to change?

I personally have an APAP and so I *think* my settings will adjust automatically if my needs change. But I am curious.

I am currently down about 7% of my initial (highest) weight. That's 16 lbs. If you were me, or even if you were you , when would you start to wonder if your settings changed?

More would depend on how you feel and you AHI. You have the data to decide for yourself.

My sleep doc said 10%, not sure where he got that figure.

I lost 20 lbs and a re-titration reduced my pressure from 14/11 to 9/5 w/0 AHI @ the lab.
He tells me that if I lose another 15, I can probably kiss the machine goodnight.
He also said I was Classic OSA patient and I have no other breathing issues like COPD,
etc.
Color me happy

If you are able to do that, more power to you!

As you may know, MoneyGal, getting down to a normal weight does not preclude most people from having apnea. Darn!

APAPs adjust as needed to help maintain normal breathing patterns. My pressure varies qujite a bit from night to night given my congestion issues. I view the median (50% above, 50% below) and 95thcentile to watch trends. Been more congested lately and my median is up a bit. You have the equipment to determne when things have improved enough to warrant a PSG to see if you no longer qualify as having OSA. As Kenny said, some won't be able to abadon equipment regardless of how much wt they lose.
