Weight loss modifies lipid peroxidation and symmetric dimethylarginine levels in obese dogs.

In obese dogs, oxidative stress is associated with inflammatory processes and systemic endocrine imbalances. Monitoring oxidative status is an early and valuable means of obesity control as it is a marker of weight loss, which leads to a reduction in oxidative status or injury potential. The objective of this study was to investgate the changes in the concentrations of thiobarbituric acid reactive substances (TBARS) and symmetric dimethylarginine (SDMA) in obese female dogs subjected to an 8-week weight-loss program.
