Hepatitis C is currently curable and does not affect life expectancy with aggressive treatment, but in the case of severe hepatitis C or cirrhosis of hepatitis C, survival without treatment may be several to ten years. Hepatitis C is a common viral hepatitis in clinical practice with a lower incidence than hepatitis B. If timely and effective antiviral therapy is taken, the cure rate is high and life expectancy is usually not affected, but if hepatitis C progresses rapidly and insidiously, it is already in an advanced stage of decompensation or even develops into cancer at the time of diagnosis, liver transplantation may be required to extend life expectancy. Clinically, if chronic hepatitis C is not treated, 5%-15% of patients will develop cirrhosis after about 20 years, and it is important to receive systematic treatment at a regular hospital hepatology department as soon as possible to save the patient’s life. Once hepatitis C is diagnosed, it is recommended to actively fight the virus and treat complications, pay attention to rest, and eat light, easily digestible food.
