After losing 100 pounds or more, formerly morbidly obese patients are often healthier than before, but they also inherit a new troubling problem: excess skin hanging off every part of their face and body. Patients still don't feel good about their changed bodies. This loose skin can inhibit movement, chafe and result in rashes and infections. After years of stretching and contracting from weight gain and loss, their skin has lost its elasticity, just like a worn-out rubber band.
