A slight increase in liver hardness often indicates that liver function is affected, and common causes include liver fibrosis, fatty liver and hepatitis. 1. Liver fibrosis: Liver fibrosis refers to the proliferation of fibrous connective tissue in the liver that occurs in the course of chronic liver disease, and is often associated with alcohol consumption, hepatitis, and immune diseases. Liver fibrosis is characterized by the proliferation and accumulation of fibrous tissue and increased liver hardness, which will eventually lead to cirrhosis if not controlled in time. 2. Fatty liver: Fatty liver is a syndrome characterized by diffuse steatosis of hepatocytes due to various reasons. The accumulation of fat in hepatocytes affects the liver hardness test, and the heavier the degree of fatty liver, the higher the liver hardness value. 3. Hepatitis: Hepatitis caused by various factors such as viral infection is the main reason for the increase in liver hardness, and the more severe the degree of hepatitis, the higher the value of liver hardness. When patients feel sick, they should go to the hospital immediately.
