Skin removal surgery is primarily a cosmetic procedure but may be medically necessary if the excess tissue causes skin chafing, pain, and infections. Many patients are uncomfortable with the appearance and feel of their baggy skin. Depending on the amount of weight you lose, you may have up to 40 or more pounds of loose, sagging skin. Skin reduction surgery is an elective procedure that removes the excess skin tissue, making it easier to shower and exercise, and improves your health if the skin folds are prone to yeast or bacterial infections.
