Bariatric Surgery Associated With Reduced Need For Diabetes Medications at Six Years Interview with:
Dr Jérémie Thereauz
Praticien Hospitalier
Chirurgie viscérale et digestive What is the background for this study? What are the main findings?

Response: Bariatric surgery has been proved to reduce type 2 diabetes in morbid obese patients. However, results of bariatric surgery at a nationwide level are lacking.

The aim of our study was to assess the 6-year antidiabetic treatment continuation, discontinuation or initiation rates after BS compared with matched control obese patients.

This large-scale nationwide study confirms that bariatric surgery is responsible for a significant 6-year postoperative antidiabetic treatment discontinuation rate compared to baseline and compared to an obese control group without surgery, and a low treatment initiation rate, with gastric bypass being the most effective procedure. What should readers take away from your report?

Response: This long term study confirms at a nationwide level, previous mid term randomized studies finding effiicency of bariatric surgery in type 2 diabetes for patients with morbid obesity associated. What recommendations do you have for future research as a result of this work?

Response: Patients and physicians must be aware that morbid obesity still remains a chronic disease even after bariatric surgery, as 50% of patients with pre-existing antidiabetic treatment remained on treatment 6 years after surgery. Our study highlights the message that these patients require careful lifelong follow-up to monitor obesity complications. Complementary medico-economic study would be helpful to determine the relevance of such treatment in a national health care system.
