A recent study published in the Lancet has found that having bariatric surgery may lower the risk of recurrent liver disease and cirrhosis. According to the report, bariatric surgery – also known as Roux-en-Y gastric bypass (RYGB) – reduced risk of severe liver disease by 66 percent, and the risk of an advanced liver fibrosis diagnosis by 84 percent. The study involved three cases of people with primary liver failure, all of whom underwent RYGB and who had a higher than normal risk of liver disease, and subsequently developed secondary liver disease or cirrhosis. Researchers took into account factors including age, race, overall health, smoking, body mass index (BMI), hypertension, and diabetes. After four years, there were 25 cases of secondary liver disease and 18 cases of cirrhosis in people who had undergone RYGB. In comparison, the overall risk for those without RYGB was 11.1 percent, cirrhosis was 10.2 percent, and severe liver disease was 12.2 percent.
This news comes after a previous study published in JAMA in February also found that bariatric surgery may prevent cardiovascular events and breast cancer.
