Why the study?
One anastomosis gastric bypass seems to carry a higher risk of malnutrition compared to Roux-en-Y gastric bypass, but existing data remain controversial.
Does one anastomosis gastric bypass compared to Roux-en-Y gastric bypass affect nutritional status in obese patients?

Comparison
RYGB (n=30) vs OAGB (n=48)

No difference in 6-month malnutrition between RYGB and OAGB; leaves open longer-term comparative risks in observational bariatric cohorts.
Does one anastomosis gastric bypass compared to Roux-en-Y gastric bypass affect nutritional status in obese patients?
Both RYGB and OAGB lead to a similar decline in nutritional status at 6 months, though OAGB may be more effective for diabetes and hypertension remission.
