Gastric surgery benefits studied

Gastric bypass surgery improves life expectancy for most morbidly obese patients, the results of a study suggest.

Researchers used a computer model to evaluate the risks and benefits of gastric bypass surgery using data from over 400,000 patients.

They found that a 42-year-old woman with a BMI of 45 would gain three years of life following surgery. A 44-year-old man with the same BMI would live an additional 2.6 years. The benefits of surgery were particularly high for younger patients.

The researchers believe that the results of this analysis could be used to inform decisions about whether to opt for gastric bypass surgery.
