Dense echogenicity of liver parenchyma is usually not serious if it is caused by fatty liver; it is more serious if it is caused by viral hepatitis. 1. Fatty liver: dense echogenicity of liver parenchyma is usually associated with fatty liver. The disease is not serious, most patients have no obvious symptoms, and can usually be improved by exercise and dietary treatment. 2. Viral hepatitis: when the virus repeatedly stimulates the liver tissue, it will cause liver parenchymal echogenicity, this kind of disease is more serious, if not treated in time, the virus will be replicated in the body, which is easy to destroy the liver cells and lead to the damage of liver function; after the condition further progresses, it may cause liver fibrosis, cirrhosis, etc. If the disease is only detected at present, it is usually related to fatty liver. If you can’t tell the type of liver disease because you only find out that the liver parenchyma has fine echogenicity, it is necessary to consult a doctor in time, improve the relevant examinations to clarify the cause of the disease, and then target treatment.
