Protein Need and Interest of " Quick Proteins " to the Obese Subject Operated by Bariatric Surgery (BIBOP) — BIBOP  

Obesity Clinical Trial

Official title: Protein Need and Interest of " Quick Proteins " to the Obese Subject Operated by Bariatric Surgery (BIBOP)

Status Completed

Clinical Trial Summary

The main objective of the study is to evaluate the protein requirement associated with postoperative weight loss caused by by-pass (shunt which leads to a certain degree of malabsorption) or sleeve gastrectomy (more technically conservative with less malabsorption), through the study of nitrogen balance. The benefit of protein supply easily absorbed and with high essential amino acids content (proteins "fast" soluble milk) on protein metabolism and muscle function will also be studied. Endotoxemia and intestinal flora variations were measured before and after bariatric surgery.

Clinical Trial Description

This is a prospective longitudinal study of the effect of bariatric surgery on protein requirements and protein metabolism, and protein supplementation interest, appropriate to the digestive tract changes, for the mass and muscle function. Three groups of patients will be studied: One group undergoing sleeve gastrectomy in Clermont-Ferrand (group 1: n = 20) will be followed by current recommendations. A second group undergoing sleeve gastrectomy in Clermont-Ferrand (group 2: n = 20) will receive during three months, protein supplement (powder whey protein ("fast")) at dose of 40g / day. 10 patients in group 1 and 10 patients in group 2 will participate in protein metabolism study. The third group undergoing gastric bypass in Lyon (group 3: n = 20) will be followed by the current recommendations and will participate in study of endotoxemia. ;
