The occurrence of liver cysts is not directly related to hepatitis B. Liver cysts are cystic lesions and benign lesions. If the liver cysts are small, they do not require special treatment and do not affect liver function. The severity of hepatitis B patients depends on the function of the liver and the degree of liver lesions caused by hepatitis B. Hepatitis B can be divided into healthy hepatitis B carriers, chronic hepatitis B, hepatitis B cirrhosis and post-hepatitis B liver cancer. healthy hepatitis B carriers do not need special treatment and only need regular follow-up review. Chronic hepatitis B patients, in addition to follow-up checkups, need timely antiviral treatment if they have indications for antiviral treatment to avoid delaying their condition. For patients with hepatitis B cirrhosis and liver cancer, further treatment should be decided according to whether there are complications, etc. In case of hepatitis B decompensated cirrhosis or hepatocellular carcinoma, the disease may be more severe, which will affect the patient’s quality of life and reduce the survival period.
