Abstract
Objective: To evaluate the patient's' profile, weight loss, comorbidities and laboratory results before and after surgery. Methods: This was a retrospective, observational case series study with data collected from electronic medical records, with a sample of 181 patients, divided according to BMI. The postoperative period was divided into 3 controls for temporal analysis. The p-value was set at 95%. Results: 75.69% of the patients were female, the average age was 38.92 years and the degree of obesity III was the most frequent (60.77%). Among the most prevalent comorbidities was hypertension (49.72%), followed by hepatic steatosis (35.91%), dyslipidemia (32.04%) and diabetes (23.20%). Roux-en-Y gastroplasty was the most commonly used technique (80.11%). Regarding weight, patients showed a progressive loss between controls. There was a reduction in glycemic levels in diabetic and non-diabetic patients, assessed by fasting glucose and glycated hemoglobin. The lipid profile showed no differences between groups. Conclusion: Despite its complexity and morbidity, bariatric surgery is beneficial to patients, promoting weight loss and controlling comorbidities.
