Diabetes after Bariatric Surgery

Can J Diabetes. 2017 Aug;41(4):401-406. doi: 10.1016/j.jcjd.2016.12.009. Epub 2017 Apr 27.


Bariatric surgery has now emerged as an effective means of glycemic control in individuals with diabetes and obesity. However, long-term data show recurrence of hyperglycemia years after the procedure. Although the exact prevalence of diabetes relapse is unknown because of attrition and limited data on long-term follow up after the surgery, a significant percentage of patients experience relapse of diabetes. The mechanism of diabetes relapse is not completely understood and is not always linked to weight regain. The clinical implications of hyperglycemia after bariatric surgery for patients and healthcare providers is reviewed.
