Uric acid monitoring have great importance in obese patients as the high levels are related to the worsening of cardiovascular and metabolic diseases, bariatric surgery is effective in improving health conditions and comorbidities.
The retrospective study consisted of patients from a private clinic in the South of BRA submitted to Y-de-Roux gastric bypass between 2015 and 2016. The pre-surgical and 6-month post-operative times were compared in relation to the lost weight and uric acid levels. The statistical analysis was performed by Software R (R Core Team, 2018), using the Tukey test at 5% significance.
The sample consisted of 120 patients, 60% women and 40% men with a mean age of 41 (+ 11.30) years. In the preoperative period the mean weight was 117.97 kg (+ 22.63 kg) and the mean uric acid was 5.47 mg / dL (+ 1.57 mg / dL). After 6 months of the surgical procedure the mean weight was 74.67 kg (+ 14.56 kg) and the mean uric acid was 4.50 mg / dL (+ 1.32 mg / dL). A significant difference (p <0.05) between the attributes evaluated before and 6 months after the surgical intervention was verified, and in the preoperative period, the means were higher than the post, for both the weight and uric acid values.
The postoperative period provided a reduction in uric acid levels, and thus, the importance of this control allows to alleviate the worsening cardiovascular risk, which is already part of the obese patient.
