New York, June 3 (IANS): The popular weight-loss surgery not only makes you look fit and healthy but can also bring spark back in your bedroom life, reveals a study.

Bariatric surgery leads to greater intimacy between life partners as going through the period becomes a "joint journey" for the couples.

"In the study, the couples felt their post-operative success was due to a joint effort on the part of both partners," said Mary Lisa Pories from East Carolina University in the US.

The research team interviewed 10 couples about the effects of the weight-loss surgery that one of the partners had undergone.

All the patients and their significant others viewed the surgery and subsequent adjustments that needed to be made as part of a team effort.

Couples highlighted the adjustment that was needed to adapt to their partners' significant weight loss.

The couples also had more energy needed to adjust to new eating habits.

On an emotional level, the couples reported more positive moods and better self-esteem.

"They also reported sharing greater intimacy and affection, and being better able to resolve conflict. Their sexual relationships also improved and, in many cases, became more enjoyable," Pories said.

A better understanding of how bariatric surgery impacts the dynamics of a couple's relationship could help physicians, nurses and social workers to support patients and their partners more effectively, the authors said.

Bariatric surgery is the most effective way to counter morbid obesity.

It results in substantial weight loss and reduces other health-related conditions.

The findings were published in Springer's journal Obesity Surgery.
