weight regain
Return of lost weight following initial successful bariatric surgery, indicating treatment failure.
Full Definition
Weight regain is the recurrence of significant weight gain following initial successful weight loss after bariatric surgery. It is typically defined as regaining 25% or more of maximum weight lost or returning to within 50% of excess weight loss. Weight regain can result from various factors including anatomical changes (pouch dilation, anastomotic dilation), behavioral factors (poor dietary compliance, inadequate exercise), hormonal changes, or psychological issues. Management may require dietary counseling, behavioral intervention, endoscopic procedures, or revisional surgery depending on the underlying cause.
