In a nutshell
This study looked at the benefits and risks of gastric bypass surgery (GBS) in patients with type 1 diabetes (T1D) and obesity. They found that GBS was associated with reduced risk of heart disease, stroke and heart failure in these patients. However it was also associated with increased episodes of high blood sugar and abuse of alcohol and drugs.
Some background
GBS is a type of surgery that reduces the capacity of the stomach to hold food. It has been shown to be an effective treatment for obesity. It has been shown to improve blood glucose (sugar) control and cardiovascular risk in obese patients with type 2 diabetes. However, there is uncertainty about whether it is effective and safe in reducing health risks in patients with T1D and obesity.
Methods & findings
This study involved 774 participants iwith T1D and obesity. 387 patients had undergone GBS, while the other 387 had not had surgery. All patients were followed for an average of 4.8 years to monitor for any health problems.
Patients in the GBS group were 57% less likely to develop heart disease, and 85% less likely to die of heart disease. They were also 82% less likely to have a stroke and 68% less likely to develop heart failure.
On the other hand, patients in the GBS group were 99% more likely to suffer a serious episode of high blood glucose leading to hospitalization. Patients in the surgery group were also 3.71 times more likely to suffer from alcohol or drug addiction compared to patients who did not have surgery.
The bottom line
This study showed that gastric bypass surgery reduced the risk of heart disease and heart complications in obese individuals with type 1 diabetes. It was also associated with an increased risk of serious episodes of high blood glucose and substance addiction.
The fine print
This study was based on medical records. Some information regarding the risk of heart disease might have been missing. More studies are needed.
