Weight-loss Surgery Averts liver damage
- Updated: May 6, 2014
A recent research reveals in Chicago at a Digestive Disease Week that bariatric surgery has the ability to assist patients in losing weight. This may also show tremendous improvements in nonalcoholic fatty liver disease.
Researchers from University of South Florida observed that bariatric surgery settled liver inflammation and also set right the early stages of liver fibrosis that scars and thickens liver tissues. This is done by decreasing the fat deposits present in the liver.
Findings indicate clearly that considering bariatric surgery is a must to cure nonalcoholic fatty liver disease that is seen in obese patients, said Professor of surgery and Tampa General Hospital director, lead researcher of the study, Michel Murr, MD and USF Health Bariatric Center.
Researchers arrived at this conclusion after comparing 152 patients with liver biopsies. They did at the time of the bariatric procedure and the second on an average of 29 months gap. The post-operative biopsies showed that the fat deposits were 70% on the liver of patients. Nearly 74% patients were resolved from lobular inflammation, while 32% patients from chronic portal inflammation and 88% from steatohepatitis.
The examination of biopsies taken as pre-operative shows patients with liver disease, especially as inflammation of liver and fat deposits can lead to cirrhosis and liver fibrosis that may be life-threatening.
The bariatric surgery is found to bring improvement in patients. Adding to this, nearly 62% patients with stage II liver fibrosis, showed amazing improvement and also one among three with cirrhosis patients showed improvement.
Dr. Murr, the professor of surgery, noted that these findings on fibrosis reversal is applicable to early-stage fibrosis only and cannot resolve late-stage liver disease. He also said that the surgery may be considered for patients with >35 BMI (body mass index) or a BMI >40, that is obesity related.
