Excess Skin

Like others have said, you really can't predict how how much loose skin you will have.  It's pretty much a guarantee with a loss of 160 pounds, you will have some, since you didn't get to that size overnight and you can't ungrow skin.  Your age is definitely in your favor.  I was 39 when I had WLS and lost 130 pounds.  I have some loose skin - not too bad.  My legs aren't great and I definitley need a bood job, but I look a million times better than I did obese.  No one would even know that I had any loose skin unless I was in a swim suit, and there's nothing I can do about it.  If I were your age, I would consider saving for plastic surgery, your insurance will not likely cover it.  At my age, I'm just happy the way I am, flaws and all.  I've also had two children, so my body was already flawed from that experience.  I think it depends where you are in your life.  Also, plastics leave A LOT of scars. . . there's always a trade off.
