Gastric Bypass: A Silver Bullet for Diabetes Remission?


About three-fourths of people with type 2 diabetes who had a weight loss procedure called Roux-en-Y gastric bypass surgery experienced remission of their diabetes within a year, according to a study published in Diabetologia, the journal of the European Association for the Study of Diabetes.

Researchers at Aarhus University Hospital in Denmark compared 1,111 people with type 2 diabetes treated who had Roux-en-Y gastric bypass surgery between 2006 and 2015 with 1,074 people with diabetes who didn’t have weight loss surgery. Weight loss surgery on people with type 2 diabetes and obesity has previously been shown in clinical trials to lead to short-term diabetes remission in up to 90 percent of participants.

After gastric bypass surgery, the Danish researchers report:

  • 65 percent of study participants were in diabetes remission after 6 months
  • 74 percent in 6 to 12 months
  • More than 70 percent during the first five years post-surgery
  • 73 percent remained in remission at the five-year mark

Diabetes remission was less likely in people who:

  • Required insulin to control their diabetes
  • Were over age 60
  • Had lower HbA1c levels prior to surgery
  • Had type 2 diabetes longer
