Sponsor's own description

The bariatric surgery is recommended for treatment of patients with severe obesity, resulting in greater weight loss and improvement of cardiovascular and metabolic comorbidities. However, weight regain is observed in patients after surgery, leading to health adverse outcomes. The purpose of this study is to identify the rate of weight regain and predictive factors of regain in bariatric patients without outpatients care regular.
