What I did was I made a mini novel-ette ( thats what my surgeon called it LOL)
I listed all of the weight loss (diet fads, pills, starvation, Adkins, walking, bla bla bla) attempts I did, the approx dates, how long I was on it, why I quit, how much ( if any) weight I lost, and how much (if I could remember) that I gained back afterwards. This was a very long list, and went back some 10 years ( all I really needed was 5 years of documentation) But I thought the more the better
Then I listed all of the aches and pains (documented by the Doc or not) that I have acquired since MO.
Then I listed emotions, Family history of MO, Cancer, Heart disease, diabetes, etc...
I also put in there that I belong to on-line and RL support groups and listed a few places that I checked out for references to prove that I have done my homework on the surgery etc...
Alot of it I went into gory details I put alot of heart and soul into it, and the surgeon was most impressed !
Hope that helps in some way!
