Will Liposuction of my Legs Change my Butt?

Liposuction of the legs and thighs can make the buttocks stand out more sometimes but usually it doesn't.  If you gain weight later, more of the fat will go to the breasts and buttocks than the legs.

Leg liposuction is a very common and effective procedure in appropriate patients.  The buttocks is supported by deep tissues below, so over aggressive liposuction below the buttocks may lead to sagging.  This is why it is very important that you see a board certified plastic surgeon experienced in liposuction. 

Good luck.
