Brief Summary

One Anastomosis Gastric Bypass (OAGB) surgery is a type of bariatric surgery (BS) which is gaining popularity worldwide and is considered to be a simple, safe and effective bariatric procedure in terms of weight loss and comorbidities resolution. However, only limited data exists on the nutritional and gastrointestinal (GI) consequences of this procedure.

This study aimed to gain information on GI and nutritional parameters from a large sample of OAGB patients living in 3 different countries.

Post-OAGB patients across Israel (n=277), Spain (n=105) and Portugal (n=111) were recruited to the study based on the time elapsed since surgery \[1-6 months (1-6M), 6-12 months (6-12M) and 1-5 years (1-5Y) post-surgery\]. Participants were asked to complete an anonymous survey delivered by SurveyMonkey®️ software which included data on demographics, comorbidities, anthropometrics, GI outcomes and satisfaction with the procedure.
