Liver Disease Lowers With Physical Activity
Chronic liver disease is increasing, partly due to the obesity epidemic, and currently there are no guidelines for the optimal type of exercise for the prevention of cirrhosis-related mortality. Researchers hope these findings will help provide specific exercise recommendations for patients at risk for cirrhosis and its complications.
“The benefit of exercise is not a new concept, but the impact of exercise on mortality from cirrhosis and from liver cancer has not yet been explored on this scale,” said Tracey Simon, MD, lead researcher on the study and instructor of medicine at Harvard Medical School and Massachusetts General Hospital, Boston. “Our findings show that both walking and strength training contribute to substantial reductions in risk of cirrhosis-related death, which is significant because we know very little about modifiable risk factors.”
Researchers observed that adults in the highest quintile of weekly walking activity had 73 percent lower risk for cirrhosis-related death than those in the lowest quintile.
“In the U.S., mortality due to cirrhosis is increasing dramatically, with rates expected to triple by the year 2030. In the face of this alarming trend, information on modifiable risk factors that might prevent liver disease is needed,” said Dr. Simon. “Our findings support further research to define the optimal type and intensity of physical activity to prevent adverse outcomes in patients at risk for cirrhosis.”
