- Researchers say people who have gastric bypass surgery for weight loss are significantly less likely to have their type 2 diabetes return, even after gaining back weight.
- Insulin use, higher A1c, and a longer duration of type 2 diabetes before surgery were more closely associated with diabetes recurrence.
- Overall, 75% of people who had gastric bypass saw their diabetes stay in remission, compared with 34% of people in the sleeve gastrectomy group.
People with obesity and type 2 diabetes who have had gastric bypass surgery are more likely to experience remission for their diabetes, even if they regain weight, than those who received a gastric sleeve procedure.
That’s according to a new study published in the Journal of the American College of Surgeons.
Researchers from the Mayo Clinic in Minnesota examined the relationship between weight loss surgery and diabetes remission.
They reviewed the medical records of 224 participants who underwent a gastric bypass at the Mayo Clinic between 2008 and 2017. They also looked at the records of 46 people who received a gastric sleeve procedure.
All participants had been diagnosed with obesity and type 2 diabetes before their gastric surgery.
The scientists monitored the participants for at least five years following surgery to see if weight gain led to a recurrence of diabetes.
Some of the findings from the new study included:
- Gastric bypass surgery resulted in high rates of type 2 diabetes remission five years after the surgery, even for people who regained a significant amount of weight.
- Participants who received a gastric sleeve were 5.5 times more likely to have their diabetes return than those who received a gastric bypass.
- Among those who regained their weight after gastric bypass surgery, about 60% still maintained long-term diabetes remission, compared to no participants in the gastric sleeve group.
- Insulin use, higher A1C (before surgery), and longer preoperative duration of diabetes were more closely associated with diabetes…
