Lipo is the most dangerous types of plastic surgery.
I'm not necessarily against all plastic surgery, but lipo seems the scariest to me. Have you had a consultation, yet? I would definitely suggest that you speak with a board certified plastic surgeon. See someone who specializes in the particular procedure, ask for lots of photos of previous work, etc. I imagine that some sort of "tuck" or "lift" would be preferable to lipo. Lipo can also leave you with loose skin.
Something else to consider, is that when you get lipo, if you gain any weight after, the fat won't go to the part that was treated, but will go to some other mystery spot. For instance, when women get lipo in the thighs, if they gain weight--it goes to their faces, stomachs, backs, etc.
