Lightweight, DS revision from RNY, and Mexico?

Revisions require the same as a virgin wls.  You need to be morbidly obese to qualify.  It would be too dangerous otherwise.  A BMI of 35-45 is considered lightweight.  If your BMI is under 35, don't even consider it.

Yes I was revised from an RNY performed in 2002 to a DS a little over a month ago, I lost 120 pound with the RNY and gained back 80 lbs. So far with the DS I have lost 38 lbs in 37 days. My insurance did cover it but my particular plan still made me pay $1500 of the cost which was doable for me. My bmi was 43.
