A decrease in liver hardness from 17 to 3.9 is a sign that a liver lesion has turned for the better. Many liver diseases can lead to an increase in liver hardness, such as hepatitis, liver fibrosis and fatty liver. When the liver hardness value is higher, it means that the liver disease is getting more serious, on the contrary, when the liver hardness drops from 17 to 3.9, it means that the condition is getting better and the liver hardness is decreasing gradually. Liver hardness is often used to help determine the degree of liver fibrosis and cirrhosis. Decreasing liver hardness indicates that the treatment is effective, and you should continue to follow the doctor’s instructions and take the medication to carry out the treatment. The gradual decrease in liver hardness should not be taken lightly and treatment should not be stopped, as this may lead to recurrence of the disease. During the treatment of liver disease, regular follow-ups and systematic treatment should be carried out.
