Obesity is a global health problem and is associated with a chronic low-grade inflammatory state. Surgical obesity treatment is being increasingly common due to its efficacy. From this, we evaluate the metabolic state improvement and inflammation remission in patients with obesity undergoing bariatric surgery. Methods: The clinical data and serum levels of leptin and adiponectin were assessed in patients with obesity before and one, three and six months after bariatric surgery. Also, serum amyloid A (SAA), monocyte chemoattractant protein-1 (MCP-1) levels were measured during the follow-up surgery and compared with a lean group of individuals. Results: Weight loss decreased body mass index (BMI), comorbidities percentage, drugs use and leptin levels. Adiponectin levels increased after surgery. SAA and MCP-1 showed no difference after surgery, but a trend decrease for MCP-1 and a significant decrease was observed when the patients with obesity were compared to the lean participants. Conclusion: Bariatric surgery alters metabolic status improving obesity-related comorbidities and the adiposity biomarkers leptin and adiponectin, but not inflammatory cytokines SAA and MCP-1.
