Walking

Physical activity, including walking and muscle strengthening activities, were associate with significantly reduce risk of cirrhosis relate death, according to research present at Digestive Disease Week (DDW) 2019. 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 relate mortality.

Liver disease can be inherit (genetic) or cause by a variety of factors that damage the liver, such as viruses and alcohol use. Obesity is also associate with liver damage. Over time, damage to the liver results in scarring (cirrhosis), which can lead to liver failure, a life-threatening condition.

The impact of exercise

Researchers hope these findings will help provide specific exercise recommendations for patients at risk; so 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; so has not yet explore 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. Dr. Simon and her team prospectively follow 68,449 women from the Nurses’ Health Study; also 48,748 men from the Health Professionals Follow-up Study, without known liver disease at baseline.

Participants provided highly accurate data on physical activity; so including type and intensity, every two years from 1986 through 2012; which allow researchers to prospectively examine the association; hence between physical activity and cirrhosis-related death. Researchers observed that adults in the highest quintile of weekly walking activity had 73% lower risk for cirrhosis-related death than those in the lowest quintile.

Muscle strengthening exercises

Further risk reduction was observe with combine walking and muscle strengthening exercises. Previous research has been limited to studies that assessed physical activity at just one point in time; so studies with very short-term follow-up. This was the first prospective study in a large U.S. population to include detailed; also update measurements of physical activity over such a prolonged period; which allowed researchers to more precisely estimate the relationship between physical activity and liver-related outcomes.

“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.”
