Usually, when mild fatty liver is found, timely treatment and improvement of lifestyle will seldom develop into cirrhosis, but may develop into cirrhosis if not effectively treated, there is no specific time. After the discovery of mild fatty liver, patients will seldom develop into cirrhosis after reasonable diet, such as low-salt, low-fat and low-calorie diet, appropriate physical exercise to reduce weight, keep a good mindset, as well as avoiding factors such as alcohol, the use of liver-damaging drugs and other factors that aggravate liver damage. The evolution of fatty liver to cirrhosis needs to go through the process of steatohepatitis, severe fatty liver, liver cell damage and abnormal tissue proliferation. Cirrhosis may develop if the patient ignores the mild fatty liver and continues to overeat, eat a high salt, high fat, high calorie diet, abuse alcohol, or if he or she has other liver diseases such as hepatitis B, hepatitis C, or alcoholic liver disease. It is recommended that patients who have mild fatty liver disease should seek further examination as soon as possible, and the doctor will give appropriate treatment measures according to the patient’s condition.
