Hepatitis C is a virus that causes inflammation of the liver. Inflammation can cause organs to not work properly. When Hepatitis C occurs, there may be very few symptoms, so most do not even know they have contracted the disease.
There are also many forms of the hepatitis C virus, none more serious than the other, but they respond differently to treatment. Even though many people with Hepatitits have no symptoms, jaundice, stomach pain, loss of appetite, nausea and fatigue are symptoms that could be noticed.
