Most people with acute hepatitis C do not have signs or symptoms of the disease. However, individuals can develop the following mild to moderate symptoms:
Most people with chronic hepatitis C don't have any initial symptoms other than fatigue. Major health problems arise as the disease progresses. This can be several years to a few decades later. Liver failure related to cirrhosis is the main long-term problem. If hepatitis C is associated with chronic hepatitis B, symptoms of chronic liver disease are more obvious.
