What does weight stability mean?

So Cigna denied my abdominalplasty saying that I haven't demonstrated documentation of a stable weight for 6 months. Anyone know what "stable means"? I was 144 on 12/3/09 and am now 133-136. is there an acceptable range?

I think it is about 5 lbs up or down, like my weight is stable for 8  months I m the same weight I go from 165 to 168 up & down, if u were 144 in Dec. and then went downto 133 - 136 next month u can be 130-133, u dont want to have Plastics with to much of a weight fluctuation.
i have had so much plastics I don't want to loose more then 5 lbs and don't want to   gain 1 lb
good Luck

 Even most doctors want you to be a stable weight (you have stopped losing) for six months before plastics.  If you have documentation (weight recorded by a doctor), then appeal the decision.
