RYGB associated with most weight loss among bariatric procedures

Racial minorities, diabetics, older patients and those with a preoperative body mass index of less than 50 lost less weight with both RYGB and SG than individuals not meeting those criteria, but the researchers noted those differences were “clinically small and generally less than 3%.”

One limitation of the study was that weight data weren’t systematically and prospectively collected, so patient weights at specific timepoints were estimated using statistical modeling.
