    One-Anastomosis Gastric Bypass (OAGB) is a popular metabolic bariatric procedure with a single gastrojejunal anastomosis.

    OAGB accounts for 7.6% of all bariatric procedures globally, with higher prevalence in Europe and Asia-Pacific regions.

    Long-term outcomes of OAGB, including weight loss and metabolic benefits, are assessed through studies with at least 10 years of follow-up.

    At 10 years post-OAGB, mean total weight loss ranged from 27% to 32%, with remission rates of type 2 diabetes and hypertension around 79%.
