INTRODUCTION: Bariatric surgery (BS) has shown to be an effective method to permanently reduce weight and improve comorbidities associated with obesity. The most common cause of hypoglycemia is medications used to treat diabetes mellitus such as insulin and sulfonylureas. The incidence of hypoglycemia after BS has been reported ranging from 0-4.5%, although most of the studies consist of small case series. The aim of this study is to analyze the incidence of hypoglycemia in bariatric patients with Diabetes type II at our institution.
METHODS: After IRB approval, a retrospective chart review of all patients who underwent bariatric surgery at our institution between 2006 and 2017 was performed. Patients with Diabetes type II and older than 18 years of age that underwent BS were included in the analysis. Fasting hypoglycemia was defined as a measurement of blood glucose level of <75 mg/ml, with or without symptoms. The perioperative period was defined as 30 days before and 30 days after the BS date. SPSS software was used to perform descriptive statistics and Chi-Square for categorical values. A P value <0.05 was considered significant.
RESULTS: A total of 4,098 patient met the inclusion criteria. The predominant gender was female 67.7% (n=2,818), the mean age was 55.2±7, mean BMI 40.6±8 and the most common ethnicity represented was Caucasian 73.9% (n=3,032). Regarding the type of surgery, 60% (n=2,465) of the patients had LSG (Longitudinal Sleeve Gastrectomy), 29% (n=1,186) had RNYGB (Roux-en-Y-Gastric Bypass), 10% (n=423) Gastric Banding (LAGB), and 0.5% (24) had revisions. The incidence of hypoglycemia pre-operatively was 2.9% (86), and 4.04% (56) in the post-operative period. When analyzing the impact demographics and each procedure on the incidence of hypoglycemia in both groups, none of the variables resulted in statistically significant differences (table 1).
CONCLUSIONS: This is the first study to analyze perioperative hypoglycemia in bariatric patients with Diabetes Mellitus type II. Our reported incidence of hypoglycemia is 3.4% (n=142) in the perioperative period of Bariatric Surgery. There was no statistical significant associated with hypoglycemia and type of bariatric procedure.
