Does sleeve gastrectomy keep weight off for life?
Sleeve gastrectomy permanently reduces stomach size but does not guarantee lifelong weight maintenance. Later regain may have biological, behavioural or medical causes and does not automatically mean personal failure. Nutritional and clinical follow-up remains part of obesity treatment.

What supports lasting benefit?
Appropriate eating, gradual activity, sleep and review of illnesses and medicines matter. Weight is not the only outcome: mobility, diabetes, blood pressure and quality of life can improve too.
If weight returns, seek assessment
Contact the bariatric team rather than starting an extreme diet or blaming yourself. Eating patterns, psychological factors, medicines and anatomy may be reviewed. Options include nutritional and behavioural support, suitable medicines or additional intervention for selected cases, not automatic repeat surgery.
Follow-up still matters when you feel well
Continue recommended supplements and tests with stable weight, with at least annual review after initial follow-up. Recurrent vomiting or difficulty swallowing needs assessment and is not a normal weight-control method.
