The time to develop cirrhosis after antiviral treatment of chronic hepatitis B is uncountable, and it may be between a few months to decades. 1. Serious condition: some patients with chronic hepatitis B have serious condition, which induces severe hepatitis and liver failure, causing a large number of hepatocellular necrosis, which should be actively treated to control the deterioration of the condition and promote the regeneration of hepatocytes. The process of liver cell regeneration is easy to induce regeneration nodules and pseudo lobar, causing cirrhosis, which is more dangerous and may only take a few months or so. 2. Slight condition: If the condition of chronic hepatitis B patients is not too serious, only a small amount of hepatocyte necrosis, this situation of liver function is good, it is possible to self-repair, but also may cause regeneration nodules and pseudo lobe, induced cirrhosis, the specific time can not be counted, it may be several decades. Therefore, it is necessary to actively receive treatment for chronic hepatitis B to avoid developing cirrhosis and jeopardizing health.
