What kind of spo2 monitoring device are you using? What percentages point to an actual problem?
I recently got a Garmin watch and turned on spo2 monitoring during the night. Most of the time I have >90%, but it sometimes drops to as low as 83% for around 15 minutes. I'm unsure how reliable the measurements are and if 83% is a problem or not.
(My current situation is the same as many others in the thread: Young, skinny, sleep problems, but the doctor is sure I don't have sleep apnoe, because I'm not fat...)
I have a similar issue where maybe once or twice a night now my sp02 drops below 90, followed by a spike in my heart rate. From the word of my sleep doctor, that is not normal for a younger person. She used this to try to justify the cost of a psg to my insurance company.
Find a different doctor. Young and fat is not the qualifying criterea. From this entire thread you can get a sense that there are a lot of people suffering out there that have sleep apnea but not fat. Also, a take home sleep study is cheap and easy and covered by insurance.
