Is plastic surgery inevitable after 100 pd weight loss

From what I understand as we gain weight we actually grow more skin and skin cells so when we lose the weight the excess skin is still there and has no where to go. I really didn't think I'd ever resort to ps but having lost 150-155 pounds in 10 months I did end up with lots of loose sagging skin and wanted it removed. I did have 2 rounds of ps after I reached my goal weight and LOVE the results. And I'm not shy about telling people my story. I'm not embarrassed to admit I had 5 ps procedures. I spent LOTS of money on this body and am proud of the way I look now. Hope that helps you. Terry Coles
