Preoperative and Postoperative (1st and 3rd Month) Metabolic Data of Patients Who Underwent Bariatric Surgery

ABSTRACT

Purpose: The growing prevalence of obesity has become a major concern. The efficacy of medical treatment, diet and behavior therapy in morbidly obese patients is limited. Obesity surgery is a treatment option for selected morbidly obese patients.
Material and Method: Data of 47 patients (n=39 women, 8 men) who underwent bariatric surgery were investigated.
Results: Out of 47 patients, 20 underwent Roux-en-Y gastric bypass (RYGB) (43%) and 27 had sleeve gastrectomy (SG) (57%). The mean age of the patients was 37±9.5 (19-59) years. 17% of patients were men and 83% were women. In the analysis of data on weight that could be found for 31 out of 47 patients, we detected preoperative and postoperative (1st and 3rd month) mean weight values as 125.4±15.9 kg, 112.7±13.2 kg (p<0.001) and 100.9±17.5 kg (p<0.001), respectively. In addition, the analysis of the data on mean fasting plasma glucose (FPG) levels which could be found for 23 out of 47 patients, showed us that preoperative and postoperative (1st and 3rd month) FPG levels were 100.9±17.5 mg/dL, 91.6±10.9 mg/dL (p=0.03) and 87.3±2.0 mg/dL, respectively. Only 1 patient had diabetes before the surgery. In the RYGB group, the mean change in weight was 12.4±5.5 kg in the 1st month and 22.2±8.6 kg in the 3rd month (compared to the weights in the preoperative period). Moreover, in the SG group, the mean change in weight was 13.7±4.5 kg in the 1st month and 23.4±5.8 kg in the 3rd month. No statistically significant difference was found between the weight changes in the 1st and the 3rd month as for surgery types.
Discussion: After bariatric surgery, significant loss in weight and reduction in FPG occurred in short-term.
