OBJECTIVE: To determine the level of oxidative stress in morbid obese patients by comparing their results to those of a normal population. MATERIAL AND METHODS: We have studied the metabolites most representative of OS, both in the blood (MDA, 8-oxo-dG, GSSG and the ratio GSSG/GSH) and in the urine (8-oxo-dG), as well as the GSH antioxidant. A descriptive analysis of the sample was performed. The Kolmogorv-Smirnov test was used to assess whether the distribution of the different metabolites was normal. In the case of normal distribution, the Student's t test was used to compare the means, the Mann-Whitney U test was used for non-parametric data, with a significance level of p < 0.05 for hypothesis contrast. RESULTS: There were 28 patients in each group, without statistically significant differences regarding age and gender. The group of patients with morbid obesity presented an average BMI of 50.1 ± 4 and 23.9 ± 6 in the group with normal weight. 67.8% of the patients with morbid obesity had other comorbidities. There were no associated pathologies in the control group. All the values for the different OS metabolites were higher in the group of patients with morbid obesity than in the control group, whereas the activity of the antioxidant systems (GSH) was lower in the group with morbid obesity. CONCLUSION: The figures of OS metabolites obtained in the group of patients with morbid obesity confirm the presence of OS in obesity at a pathological level given the differences obtained in the group of normal population.
