Bariatric Surgery and Type 2 Diabetes Remission Rates: a Retrospective Cohort Study Comparing Military Veterans and Beneficiaries.

Abstract

The disease burden of type 2 diabetes (T2D) costs the military healthcare system an estimated $1.66 billion annually. Thirty-four percent of veterans and 28% of military beneficiaries are obese, a common feature of T2D. Bariatric surgery is a viable treatment for T2D, whether if long-term remission of T2D post-bariatric surgery occurs remains unknown. The purpose of this study was to assess differences between outcomes of veterans and military beneficiaries following bariatric surgery. A retrospective cohort study assessed retirees and beneficiaries diagnosed with T2D who had bariatric surgery between 2005 and 2015. Outcomes included T2D remission and vitamin and mineral deficiencies each year for 5years post-op, analyzed via ANOVA. Ninety-one patients, 46 beneficiaries and 45 retirees, were included with a mean age of 51 and 57, respectively. No significant differences between T2D remission and vitamin/mineral deficiencies 5years post-op were found between groups. Patients with uncontrolled diabetes before surgery were less likely to achieve T2D remission for all 5years post-op, regardless of military affiliation (p < .05). Veterans do not have better rates of T2D remission or weight loss following bariatric surgery than other populations. Control of T2D pre-surgery is a potential clinical indicator of T2D remission success following bariatric surgery.
