SALT LAKE CITY — Diet and exercise alone may not be enough to help people who are severely overweight.
A Utah-based study and one of the first of its kind in the U.S. has shown that, for severely obese individuals — those with a body mass index greater than 35 — gastric bypass surgery can lead to long-term health benefits that may be unobtainable with just making lifestyle changes.
"We know that with gastric bypass surgery, patients lose a substantial amount of weight," said Dr. Ted Adams, lead author of the study, and research and clinical director for the Intermountain Health and Fitness Institute at LDS Hospital.
Patients typically lose an average of 100 pounds and after two years, a previous study indicated that patients maintained a loss of about 35 percent of that initial weight.
"Now, six years out, there's still a significant amount of weight that has remained lost," Adams said. "But the benefits go beyond weight loss. We also found that patients who had the surgery were less likely to develop serious health problems like diabetes, high blood pressure and high cholesterol."
Researchers followed the medical records and practices of 1,156 individuals, ages 18 to 72, recruited from throughout Utah. Of those, 418 people had Roux-en-Y gastric bypass surgery, 417 were seeking to have it, but didn't mostly because their insurance wouldn't cover it, and a third group of 321 individuals were not seeking to have surgery.
The study found that gastric bypass surgery was effective in maintaining weight loss, as surgical patients maintained a loss of an average of 34.9 percent of their initial weight even two years after the procedure. They kept off an average of 27.7 percent six years later, Adams said.
Study participants in the groups that did not receive the surgery did not show an increase or decrease in weight, regardless of the various medical or non-medical approaches to losing weight that they participated in during the study.
Adams said that weight loss methods are typically considered successful if just a 7 percent weight loss is maintained.
In addition to helping patients maintain their weight loss, gastric bypass surgery was found to decrease the risks of cardiovascular and metabolic symptoms and diseases, such as high blood pressure, high cholesterol and type 2 diabetes.
