In people with Type 2 diabetes, obesity, and chronic kidney disease, bariatric or weight loss surgery can significantly protect kidney function and reduce the risk of kidney failure, finds a study.

The study, published in the journal Annals of Surgery, showed that bariatric surgery was associated with a 60 per cent lower risk of progression of kidney disease and a 44 per cent lower risk of developing kidney failure or death in comparison to the nonsurgical group.
