Fatty Liver vs Enlarged Liver: What’s the Difference?
Fatty liver and enlarged liver are related but not identical terms. Fatty liver refers specifically to fat accumulation in liver cells. Enlarged liver (hepatomegaly) means the liver has increased in size, which can occur due to multiple causes, including fatty liver, infection, inflammation, or other liver diseases.
