It is difficult to decide which adolescents would benefit from this type of surgery. This is a decision that must involve the patient, his or her family, physicians, nutritionists, and often psychologists. An adolescent who is considering this surgery is extremely overweight and has not been able to lose weight through diet and exercise but is both healthy enough and mature enough for the surgery. The adolescent also needs to understand that the surgery is not a quick fix; it will lead to a different lifestyle afterward. After recovering from the surgery, the adolescent will need to participate in and monitor diet and exercise and take medicines and possibly vitamins, as well as continue to have careful follow-up by a physician.
