Low Oxygen Level

[instep]

If I quit smoking will my oxygen levels return to normal?. I had the lung function test done, it appears to be okay. I exercise daily 3 miles on a treadmill. I do not want anymore tests, I think this would be a goal if I can return my oxygen levels to normal without anymore testing.

i'm no nurse or doctor but my uncle is a doctor, if you quit smoking for 10  years your lungs will be back to read and healthy. xx
