Conditions

Aging Overweight and Obesity Bariatric Surgery Candidate Protein Malabsorption

Summary

The goal of this clinical trial is to investigate protein digestibility after bariatric surgery. Does protein digestibility decrease after Roux-en-Y-Gastric Bypass? Does protein digestibility decrease after Sleeve Gastrectomy surgery? Does protein digestibility effect the ability to meet protein requirements?
