New York: Besides making you slimmer, a successful weight-loss surgery can also lead to increased activity in the bedroom for years, suggests new research.
"Limited research has suggested that bariatric (weight-loss) surgery is associated with short-term improvements in sexual function," said lead researcher Kristine Steffen, associate professor of pharmaceutical sciences at North Dakota State University in Fargo, US.
"This study shows these improvements are long lasting," Steffen noted.
The study involved more than 2,000 people -- nearly 80 percent women - who underwent bariatric surgery.
They were surveyed about their sex lives for five years after the surgery.
One year after the procedure, most patients reported improvement in their sex lives.
What is more, the researchers found, the effects continued even after five years after the surgery.
At the five-year point, about 52 percent of women and 58 percent of men remained moderately-to-very satisfied with their sexual function as compared with about 31 percent and 28 percent, respectively, before surgery.
Similarly, about 39 percent of women and 55 percent of men said they were more sexually active after the surgery than they had been before.
The increase in sexual satisfaction could be linked to reduction in depression symptoms as a result of the surgery, the researchers said.
The findings were presented at Obesity Week 2015 in Los Angeles, US.
