Why this matters
Elevated liver fat indicates fatty liver disease. This condition often develops silently, increasing risk for diabetes, cardiovascular disease, and progressive liver damage. Advanced stages can lead to fibrosis or cirrhosis with symptoms such as jaundice, swelling, and confusion. Because liver fat is strongly influenced by body weight, diet, physical activity, and alcohol intake, early detection is valuable since lifestyle changes can often reverse fatty liver before permanent damage occurs.
