5 Year History ???? When you hardly ever visit a DR
I also have Aetna and I never go to the Dr unless I'm knocking on death's door! I sent for records from every single Dr and hospital that may have treated me in the past 7 years. I was lucky enough that I was able to find one note for each of the past 5 years that had my weight and height listed. Aetna is very strict with their requirements ( the insurance coordinator at my surgeon's office said that they are a nightmare to deal with). Try to get all of your records. Maybe you'll be surprised.
You may be able to use employer physicals, and any gov't document. I forget if weight is asked on passport, but it would be a "self-reporting" of wt, and they may not consider it. Some states have wt on driver's lic. If you were ever fingerprinted for a background check for a job, they usually ask weight. HHmmm, or if you were ever arrested???.... (sorry, just trying to help).
I do know one person *****fused to ever have her doc weight her, but I think she at least had some documentation in the doctor's notes that she refused, yet was Morb Obese as a diagnosis.
Good luck,
