Gastric bypass 4 yrs out and gaining weight and seem unable to lose it, like before the surgery. How do I get back on track?

Read. Maintenance weight, while difficult to predict for an individual patient, is dependent on multiple factors, including the type of bariatric procedure performed, physiological adaptation, occurrence of life events (eg, pregnancy, menopause, smoking cessation), prescription of weight gaining medications, adherence to appropriate eating and exercise behaviors, patient age, functional status, and othe.
See your doctor. The surgeon you used has a comprehensive approach to assure success in this elective procedure. My guess is that your diet has strayed from the plan, so revisit the bariatric team to get specific guidance.
