Prevalence and pathophysiology of early dumping in patients after primary Roux-en-Y gastric bypass during a mixed meal tolerance test

Wijma et al. are spot-on in their assessment that early dumping syndrome after Roux-en-Y gastric bypass is poorly defined and incompletely understood. There has been quite variable data reported on the prevalence of early dumping after gastric bypass, ranging anywhere from 3% to 80% [1,2], with many papers relying only on self-reported symptoms. The current study helps clarify the issue by combining not only symptoms reported via a validated Dumping Severity Score, but with vital signs as well as incretin blood samples at defined time points after a well-characterized mixed meal.
