Statins are mainly used for lipid-lowering treatment, not for the direct treatment of fatty liver. The reason why statins are used to treat fatty liver is that patients with fatty liver have disorders of lipid metabolism, that is, fatty liver caused by obesity or overweight, so doctors need to give patients statins to lower their blood lipids for treatment. Patients with fatty liver who are obese or overweight need to lose weight and regain normal weight in order to facilitate the recovery of fatty liver, and if necessary, statins should be added to lower lipids. For patients with fatty liver with liver function impairment, liver protection and enzyme-lowering drugs should be given in cooperation with a specialist when necessary. Therefore, statin is not directly used for the treatment of fatty liver, but for lowering blood lipids, which can help to relieve fatty liver.
