In the January 4, 2012, edition of JAMA, researchers at the University of Gothenburg in Sweden determined that bariatric surgery is associated with reduced risk of cardiovascular deaths and events such as heart attack and stroke in obese individuals.  As the researchers note, “this is the first prospective, controlled intervention to our knowledge reporting that bariatric surgery is associated with reduced incidence of cardiovascular deaths and cardiovascular events.”

In the January 4, 2012, edition of JAMA, researchers at the University of Gothenburg in Sweden determined that bariatric surgery is associated with reduced risk of cardiovascular deaths and events such as heart attack and stroke in obese individuals.  As the researchers note, “this is the first prospective, controlled intervention to our knowledge reporting that bariatric surgery is associated with reduced incidence of cardiovascular deaths and cardiovascular events.”

The correlation between obesity and the presence of “co-morbidities” such as type 2 diabetes, hypertension and other conditions has been supported by clinical data, there has been a notable absence of direct data on the association between bariatric surgery and improvements in overall health that reduce the risk of death.  The Gothenburg study confirmed this specifically by studying 2,010 obese patients who underwent bariatric surgery contrasted to a control group of 2,037 obese individuals receiving standard care.

The authors were careful to note that the reduction in risk only correlated with modest weight loss from bariatric surgery and that subsequent, greater weight loss did not further reduce risk.  The authors also note that additional research is needed on any possible correlation between weight loss other than by bariatric surgery and reduction in risk of death.

Below is illustrated the market for various obesity treatment options, with expected product revenues in 2013 and growth to 2019.
