The American Heart Association has released a statement saying that the benefits of undergoing a bariatric surgery might be greater than its side effects for some of the severely obese people.
The weight loss surgery causes a number of adverse effects in patients including bloatedness, diarrhoea, pneumonia and infections.
However the American Heart Association said that while the surgery should not be conducted on everybody, the benefits that severely obese people get from such a surgery far outweighs the ill effects.
Saying that the statement is not an endorsement of the surgery, lead author Dr Paul Poirier wrote, "Bariatric procedures are generally safe; however, this is not a benign surgery. At the moment, bariatric surgery should be reserved for patients who can undergo surgery safely, have severe obesity and have failed attempts at medical therapy."
The report has been published in the recent issue of Circulation.
