Brief summary

Was performed a longitudinal, study with twenty patients recruited for the bariatric surgery group and 20 for clinical treatment. The analysis of HRV and endothelial function were performed through peripheral arterial tonometry, in patients with obesity before and after three months of bariatric surgery. Were also analyzed GLP-1, insulin and glucose at fast, and 30 and 60 minutes. The results were compared in parallel with a control group with clinical treatment for obesity.

Detailed description

To assess the pathophysiological mechanisms that leads the benefits in cardiovascular risk after bariatric surgery, through the autonomic nervous system and endothelial function, was performed a longitudinal, study with twenty patients recruited for the bariatric surgery group and 20 for clinical treatment. The analysis of HRV and endothelial function were performed through peripheral arterial tonometry, in patients with obesity before and after three months of bariatric surgery. Were also analyzed GLP-1, insulin and glucose at fast, and 30 and 60 minutes. The results were compared in parallel with a control group with clinical treatment for obesity.
