Background: Oxidative stress is increased in obesity, leading to endothelial dysfunction, atherogenesis, and platelet aggregation. The purpose of this study was to determine the effects of weight loss after bariatric surgery on serum lipids, malondialdehyde (MDA, a marker of oxidative stress), oxidized low-density lipoprotein (oxLDL, which is increased in obesity and causes endothelial dysfunction), paraoxonase (PON-1, which inhibits lipid peroxidation), leptin and plasminogen activator inhibitor type-1 (PAI-1, which contributes to a thrombotic state).
