Letter From Dr And Photos For Insurance Approval

I dont go to the dr on the regular but the insurance calls for 3 year of being overweight. And in 2009- I was 180 at 5'1 and it climb steadily the next few years to my current weight 209 my dr said that he would write the letter and he needs photos so I havent always had a bmi of 40 but pretty close. I am finding my fattest photos. Has anyone had to do this? I hate insurance companies
