Weight loss following bariatric surgery 'can be sustained long-term'

1 September 2016

The weight loss benefits of bariatric surgery can be sustained over a long-term period, a new study has indicated.

Duke University researchers examined differences in weight change up to ten years after surgery in 1,787 individuals who underwent Roux-en-Y gastric bypass (RYGB) operations, as well as 5,305 nonsurgical matches. The patients had an average age of 52.

Patients undergoing RYGB surgery were shown to have lost 21 per cent more of their baseline weight at ten years than nonsurgical matches, with only 3.4 per cent of patients undergoing RYGB returning to within five per cent of their baseline weight after this amount of time.

These results provide further evidence of the beneficial association between surgery and long-term weight loss, as has previously been demonstrated in shorter-term studies of younger, predominantly female patients.

Nevertheless, the report called for further research into the potential complications associated with surgery to ensure patients are able to make informed decisions.

The researchers noted: "Engaging patients in a high-quality shared decision-making conversation about their weight loss treatment options - including no treatment - is critical because prior studies have found that patients have unrealistic expectations of the weight loss that bariatric surgery will help them achieve."
