Gastric bypass surgery linked to improved heart function

8 February 2011

Researchers have linked gastric bypass surgery to improved heart health in patients suffering from severe obesity.

According to the Utah Obesity Study, which was spearheaded by Dr Theophilus Owan of the University of Utah School of Medicine in Salt Lake City, US, the increasingly popular weight loss procedure results in "reverse cardiac remodelling" – i.e. the size of the heart begins to return to normal.

Published in the Journal of the American College of Cardiology, the two-year study showed that a number of factors could have caused the cardiovascular changes to take place following surgery – including the resulting weight loss itself.

"Marked weight loss in patients undergoing gastric bypass surgery was associated with reverse cardiac remodelling and improved left ventricle and right ventricle function," the researchers claimed.

They added that their results "support the use of bariatric surgery to prevent cardiovascular complications in severe obesity".

Recent Italian research showed that gastric bypass surgery can add years to obese patients lives.
