How long does it take for liver fibrosis to develop into cirrhosis cannot be generalized, and it is necessary to consider the condition comprehensively in order to determine the common causes, such as hepatitis viruses and long-term alcohol abuse. In less severe cases, the progression of cirrhosis can always be avoided with active treatment, while in some patients, the progression to cirrhosis may take decades. The cause of liver fibrosis may be related to hepatitis viruses, chronic alcohol abuse, irregular diet, and prolonged unfavorable factors can lead to liver cell damage. If the extent of damage is mild and the regeneration of liver cell fibrosis is not severe, the structure of the liver is not seriously damaged. After professional medical treatment plus active personal review and protection, the liver will not develop into cirrhosis. If the cause of the disease exists for a long time, the scope of liver damage continues to increase. At this time, excessive deposition of fibrous tissue, after damage and incomplete regeneration of liver cells under the dual role of the patient as short as 1 to 2 years, or as slow as decades can progress to cirrhosis. Once cirrhosis occurs, it is difficult to be reversed, and other complications such as portal hypertension occur along with the disease progression. It is recommended to receive regular treatment at an early stage after diagnosis of liver fibrosis, and at the same time adjust the diet, develop low-salt, low-fat eating habits, regular work and rest, and avoid staying up late.
