Liver fat fraction (%PDFF)

Fatty liver disease occurs when excess fat (more than 5–10% of the liver's weight) accumulates in liver cells. It affects approximately 30% of European adults. There are two main types: alcoholic fatty liver disease (AFLD) caused by excessive alcohol intake, and non-alcoholic fatty liver disease (NAFLD) linked to metabolic factors like obesity and insulin resistance.

Early-stage fatty liver disease is often completely asymptomatic. When symptoms do appear, they typically include persistent fatigue, mild discomfort in the upper right abdomen, and occasional appetite loss. Most cases are discovered through blood tests or imaging ordered for other reasons.

Yes, particularly in early stages. Simple steatosis and early steatohepatitis are largely reversible through lifestyle changes, before significant scarring (fibrosis) has developed. A weight loss of 7–10%, 150 minutes of weekly exercise, and a balanced, low-glycemic diet significantly reduce liver fat and support regeneration.
