Obese people who have stomach surgery to help them lose weight will halve their risk of heart attack according to new research. The procedures, known as bariatric surgery, involve techniques such as gastric banding, and Roux en Y surgery.New research published today in the International Journal of Cardiology reviewed data from 14 studies involving more than 29,000 patients who underwent bariatric surgery. It reveals that death rates were reduced by 40 per cent, and that heart attacks in particular were reduced by half — compared to obese people who did not have surgery.
The studies are the the first comprehensive review of the impact of surgery on heart disease, stroke disease and death.Senior author Dr Yoon Loke from UEA’s Norwich Medical School said: “Obesity is a worldwide problem with significant consequences on individuals and society. It is associated with heart disease, type 2 diabetes, many cancers, and a shorter life expectancy.Latest data from North America shows 1 in 3 Canadians is obese. We looked at the outcomes for patients who undergo bariatric surgery, and compared them to figures for obese people who had not received surgery. We saw that surgery was potentially life-saving and could lower the risk of having a heart attack and stroke by almost 50 per cent.”These findings suggest that surgery should be seriously considered in obese patients who have a high risk of heart disease.
