Let seem to really return back to where is was, but i think your health has a lot to do with it too. They call me frail which in some ways better than over weight I am told.

Thank you for your useful and insightful thoughts. Much appreciated and I will continue to hang in there.

Jean “an insult to the body”.
A perfect expression.

Surgery is an insult to the body and for those of us with breathing problems, it's an insult to the lungs as well, even if the surgery isn't in the lungs. it's quite normal to have difficulties with O2 saturation levels after surgery. Keep working on your recovery, including exercise. Work with a PT if you need exercises that are specific to you and the surgery you had. You should be able to work your way back to where you were prior to the surgery, but it will definitely take time. Don't get discouraged.
