Is it bad to want liposuction and only be 21? Would I be able to have kids when I'm ready in a few years?

Thank you for your question.  If you are healthy and have isolated fat deposits, then you are a candidate.  The age really does not matter.  Liposuction will not affect your ability to have children.  If you gain weight after liposuction, however, you will put fat back onto your body, sometimes in the same locations you had liposuction. Good luck, 

Thanks for your inquiry.  A 21 year old can have liposuction if they choose.  This procedure should not affect your ability to have kids in the future.
