%X <B>BACKGROUND: </B>Weight loss failure after bariatric surgery imposes great stress on patients and surgeons and great costs on healthcare systems. The literature review shows that weight loss failure is the most common cause of redo bariatric surgery. Therefore, identifying the predictors of weight loss failure in patients in the early stages can help bariatric surgeons. The present study aims to determine the association between primary weight loss and long-term weight loss outcomes.<BR><B>METHODS: </B>This retrospective cohort study was conducted on 329 patients undergoing OAGB who were followed for 60 months. For the prediction of short-term (24 months) and long-term (60 months) successful weight loss and weight regain, we used %TWL and BMI at any regular follow-ups.<BR><B>RESULTS: </B>In preoperative indices, age, sex, DLP, hypothyroidism, and HTN were not significant to predict successful short-term and long-term weight loss but %TWL at 12 months is a significant predictor of successful weight loss in short-term and long-term follow up. In the prediction of weight regain, preoperative indices (except BMI) were not significant but 12-month %TWL was a significant predictor.<BR><B>CONCLUSIONS: </B>This index can help surgeons find these patients early and provide helpful instructions to manage their issues more promptly to reach better weight loss outcomes.
