The study, presented at Digestive Disease Week 2019, found that physical activity was linked to a significant reduction in the risk of cirrhosis-related death. According to the researchers, death from liver disease is increasing dramatically, referring to the rise in chronic liver disease due to the obesity epidemic. The researchers hope that their findings could help provide specific exercise recommendations that may benefit those with chronic liver disease.
“In the US, 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 Lead Researcher Tracey Simon M.D., instructor of medicine at Harvard Medical School and Massachusetts General Hospital.
Previous studies were limited in scope, mostly assessing physical activity at only one point in time or had very short follow-up periods. Simon and her team presented the first prospective study in a large US population that included updated physical activity measurements over a prolonged period. This longer period allowed the research team to make accurate estimates on the relationship of physical activity and liver disease mortality.

To determine the association between physical activity and a decreased risk of liver disease mortality, the researchers collected data from 68,499 women from the Nurses' Health Study and 48, 748 men from the Health Professional's Follow-up Study. The participants provided accurate data on their weekly time spent on walking, individual aerobic activities and resistance exercises every two years, from 1986 to 2012.
The researchers recorded 269 deaths throughout their study, of which 148 were women and 121 were men. From the results, the researchers found a reverse association between physical activity and cirrhosis-related mortality. Adults who exercised frequently had a 73 percent lower risk of dying from cirrhosis compared to adults who exercised the least. Also, they observed that energy expenditures from both walking and vigorous activity resulted in similar levels of risk reduction. Resistance exercises, however, were independently associated with reduced liver disease mortality risk.
“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 Simon. “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.”
The liver is a powerhouse that needs to be protected to promote overall health. The US study showed that exercising regularly promotes liver health. But if working out seems overwhelming for you, there are other ways to support your liver. Here are a few foods you can add to your diet to help protect your liver from disease:
The liver is an important organ that plays an important role in various bodily processes. You don't even have to do rigorous exercises to protect it from disease -- walking for several minutes every day can have beneficial effects. Learn more about preventing liver disease at LiverDamage.news.
