Obesity, simply defined as excessive bodyweight, is very risky. Treatment of obesity should be multi-disciplinary, i.e. treatment team must contain general surgeon, dietician, endocrinologist, psychiatrist and plastic surgeon. Plastic surgeon plays a role after loss of weight in the treatment process of obese patients. Plastic surgery operations are performed in order to correct deformities on the body of patient losing weight through sports, diet, psychiatric support and weakening surgical interventions. Prolapses develop in obese patients losing weight. These prolapses focus on abdominal zone, breasts, arms, legs, buttocks and back. As the patient loses weight, surplus tissues should be removed and skin should be lifted. Skin prolapses and sags impairing the life quality of patient are corrected by multi-step operations.

Therefore, operations are planned and priorities are decided together with the patient. Skin prolapses on abdominal zone may cover genital zone, thereby causing difficulties in hygiene and preventing mobility of patient. Excessive sags on arms and legs cause frictions during movements of patient, thereby creating difficulties by massive effect, and causing diaper rashes and wounds. Both males and females may suffer from excessive sags in breasts after weight loss. This negatively affects the patient in psychosocial terms. As a result of excessive weight loss, sags may develop in face and neck zone as well, which also require lifting operations. Purpose of these operations is to improve the life quality of patient.
