Introduction: Type 2 Diabetes Mellitus (DM2) remission after bariatric surgery can be achieved in 72% of cases. This mechanism is not fully dilucidated; however, it could be caused by the action of glucose direct deposit in the jejunum.
Objective: To assess the preoperative eating behavior impact in postoperative DM2 remission.
Materials and methods: A retrospective chart review among obese and type 2 diabetic patients that underwent bariatric surgery in a tertiary hospital center. Preoperative BMI and eating behavior were evaluated, as well as postoperative diabetes status and BMI.
Results: A total of 198 patients underwent bariatric surgery, of which 128 presented an altered glucose metabolism, corresponding to 64 cases of DM2 and 64 pre-diabetic patients. Most diabetic patients were women (78%), with initial mean weight of 114.7 kg, while male patients presented 154.5 kg. The mean BMI was 42.1 kg/m2 and 49 kg/m2, respectively. In the eating behavior evaluation, 28% of the diabetic patients were classified as volume-eater, 15.6% as sweet-eater and 6.25% as snack-eater. Half of the sample presented a mixed-pattern eating behavior, being the most frequent combination the Volume-sweet-eater mixture. Most diabetic patients (71.8%) underwent a gastric bypass (GBP) and 28.2% underwent a vertical sleeve gastrectomy (VSG). In the GBP group, 46% of patients achieved diabetic remission at 5 years of assessment and there were no cases of remission in the VSG group. The eating behavior that presented most cases of remission was the volume-sweet-eater pattern with 100% of cases of normoglycemia after bariatric surgery (P=0.004). The other patterns did not present statistically significant remission.
Conclusion: It seems that there´s an association between the volume-sweet-eater behavior and post-operative DM2 remission.
