More than 5% fat is mild fatty liver, more than 10% is moderate fatty liver, more than 25% is severe fatty liver. When the total amount of fat in the liver more than 30%, with B-to check out, was diagnosed by B-ultrasound as “fatty liver.” Fatty liver patients, the total fat up to 40% to 50%, some up to 60%, mainly triglycerides and fatty acids, and phospholipids, cholesterol and cholesterol increased only a small amount.

Not only because of the rising prevalence of fatty liver and rejuvenation trend, more importantly, patients with fatty liver
