Obesity is a well-known risk factor for a host of cardiovascular problems, including heart attack, stroke and heart disease, but a recently published study in the Journal of the American Medical Association suggests that weight loss surgery can significantly reduce that risk. Researchers found that bariatric surgery lowered the risk of heart attack and stroke by 33 percent and the risk of death from heart-related causes by nearly 53 percent. The results are based on a Swedish study of over 4,000 obese adults that compared the outcomes of people who had bariatric surgery with those that did not.
The study showed that diabetes and risk factors for diabetes, including high blood sugar, were significant indicators of post-surgical cardiovascular benefit. Body mass index (BMI) before surgery and weight loss after surgery were not associated with reduced incidence of cardiovascular events, based on the study results.
Currently, candidates for bariatric surgery must have either a BMI over 40 or a BMI over 35 with one or more obesity-related condition, such as diabetes, high blood pressure or sleep apnea. The findings of this study highlight the importance of considering diabetes, in addition to BMI, when deciding whether bariatric surgery is the best treatment option.
