Liver disease is a growing concern in Canada and health officials are warning that Canadians don't always know when they are at risk.

The CBC's Dr. Meera Delal explains that hepatitis B, hepatitis C, alcoholism, and fatty liver disease are all contributing factors to cirrhosis, or scarring of the liver, and other complications of liver disease.

In one recent study on hepatitis C screenings in B.C., eight per cent of the 450 patients screened had the virus but were unaware of their infection.

Overweight and obese members of B.C.'s population may have, or be at-risk of developing, fatty liver disease, whether or not they are frequent consumers of alcohol.
