The time it takes for fatty liver alone to develop into liver fibrosis can be months, years, or even decades.
Simple fatty liver can slow down the course of liver fibrosis or even return to normal through medication and lifestyle improvements. Therefore, early treatment is very important.
Delaying the progression of simple fatty liver to liver fibrosis requires improving lifestyle. For example, weight loss, moderate exercise, low-fat diet, less oil diet, quit smoking and alcohol.
For simple fatty liver caused by high blood fat, there are medications in addition to exercise and diet control. Drugs to lower cholesterol include atorvastatin, simvastatin, etc. Drugs to lower triglyceride include fenofibrate, etc.
The use of medication should be under the guidance of a doctor.
