Long-Term Weight-Loss in Gastric Bypass Patients Carrying Melanocortin 4 Receptor Variants
BACKGROUND The melanocortin 4 receptor (MC4R) critically regulates feeding and satiety. Rare variants in MC4R are predominantly found in obese individuals. Though some rare variants in MC4R discovered in patients have defects in localization, ligand binding and signaling to cAMP, many have no recognized defects. SUBJECTS/METHODS In our cohort of 1433 obese subjects that underwent Roux-en-Y Ga...
متن کاملMelanocortin-4 Receptor Mutations and Polymorphisms Do Not Affect Weight Loss after Bariatric Surgery
Bariatric surgery is the most effective long term weight-loss therapy for severe and morbidly obese patients. Melanocortin-4 Receptor (MC4R) mutations, the most frequent known cause of monogenic obesity, affect the regulation of energy homeostasis. The impact of such mutations on weight loss after bariatric surgery is still debated.The objective is to determine the impact of MC4R status on weig...

Bariatric procedures performed in the United States have increased from 16,200 in 1992 to approximately 205,000 in 2007. In 2002, our center began offering laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures on an out...
متن کاملMechanisms of weight loss after gastric bypass and gastric banding.
The obesity epidemic is a major health problem that is associated with increased morbidity and mortality. Gastrointestinal hormones have been increasingly understood to be an important element in appetite regulation. Several gastrointestinal hormones can contribute to obesity by modulating the activity of the gut-brain axis. Bariatric surgery is currently the most effective therapy for signific...
متن کاملFactors associated with weight loss after gastric bypass.
BACKGROUND Gastric bypass (GBP) is the most common operation performed in the United States for morbid obesity. However, weight loss is poor in 10% to 15% of patients. We sought to determine the independent factors associated with poor weight loss after GBP. DESIGN Prospective cohort study. We examined demographic, operative, and follow-up data by means of multivariate analysis. Variables inv...
