Boston (DbTechNo) - Results of a new study support the theory that performing bariatric surgery on obese patients can extend their overall life span.

This is the finding of a new study carried out by researchers from the University of Cincinnati Academic Health Center.

The surgery involves wrapping a band around the patient’s stomach thus shrinking it, so that when they eat they feel fuller from eating less food.

Over time, the less a person needs to eat, the more weight they end up losing.

In the study, researchers analyzed previously performed clinical trials of obese patients and the benefits of undergoing weight loss surgery when it came to life span.

They found that for a 42-year-old woman with a body mass index of 45 weight loss surgery could extend her life by up to 3 years.
