Diabetes remission of bariatric surgery and nonsurgical treatments in type 2 diabetes patients who failure to meet the criteria for surgery: a systematic review and meta-analysis

Abstract

Abstract Background The efficacy of bariatric surgery in moderate and severe obesity patients to reach diabetes remission is clear, but for mild obesity patients, the choice of surgical and non-surgical treatment is still unclear. This study we aim to compare the effect of surgical and nonsurgical treatment on patients BMI < 35 kg/m2 to reach diabetes remission. Method We searched relevant articles publish between Jan 1,2010 and Jan 1, 2023 in the following databases: Embase, PubMed/MEDLINE, Scopus, and Cochrane Library. We got the OR, MD and P-value using random effect model to compare the efficiency between bariatric surgery and nonsurgical treatment on diabetes remission, the reduction of BMI, Hb1Ac and FPG. Results In 7 included studies including 544 participants, bariatric surgery is more effective than non-surgical treatment to reach diabetes remission [OR 25.06, 95%CL 9.58–65.54]. Bariatric surgery more likely resulted in significant reductions in HbA1c [MD -1.44, 95%CL (-1.84)-(-1.04)] and FPG [MD -2.61, 95%CL (-3.20)-(-2.20)]. Bariatric surgery may resulted in reductions in BMI [MD -3.14, 95%CL (-4.41)-(-1.88)], which more significant in Asian. Conclusion In type 2 diabetes patients who BMI < 35 kg/m2, bariatric surgery is more likely to achieve diabetes remission and better blood glucose control than nonsurgical treatment.
