Weight losses following bariatric surgery have varied widely, depending on length of follow-up and various pre-surgical characteristics of patients undergoing surgery.


One hundred thirty one patients had a detailed presurgical psychiatric evaluation. Patients were assessed clinically for 2 years after surgery and at follow-up a mean of 5.7 years after surgery.


Mean presurgical body mass index (BMI) was 52.9 kg/m2; therefore, many patients had 'super obesity'. Two-thirds of the patients were located a mean of 5.7 years after surgery. The mean change in BMI at follow-up was 25% and the mean weight loss was 27%. One-third had excellent or good weight outcomes using the Griffen criteria. Five patients had died by follow-up. There was no relationship between age, gender, or fat content presurgically and weight loss at follow-up, although presurgical weight was associated with greater weight loss at follow-up. Weight regain began 2 years after surgery. There was no relationship between the presence or absence of a presurgical psychiatric diagnosis and weight loss at follow-up. There was also no relationship between the presence of a presurgical psychiatric diagnosis and various mental health parameters at follow-up. Satisfaction with the surgery was marginally associated with weight loss but significantly associated with improved mental and physical health.


Mean weight losses were less than have been previously reported with gastric restriction procedures but the follow-up was longer than usually reported and many patients had 'super obesity' prior to surgery. The implications of 'super obesity' for weight loss are discussed.
