Food Tolerance and Eating Behavior After Roux-en-Y Gastric Bypass Surgery.

Background: Roux-en-Y gastric bypass (RYGB) surgery often leads to food intolerance, especially protein intake.

Aim: This is to investigate the association of food intolerance with protein intake and chewing parameters in patients who underwent RYGB surgery 2 years prior.

Methods: An observational study was carried out in 30 patients aged between 18 and 60 years old with at least a 2-year postoperative period since undergoing RYGB surgery.
