Fatty liver, also known as hepatic steatosis, is a condition characterized by the accumulation of excess fat in the liver cells. This condition can occur without causing significant symptoms, but it may lead to liver inflammation and damage over time. Fatty liver is commonly associated with obesity, excessive alcohol consumption, type 2 diabetes, and metabolic syndrome. There are two main types: alcoholic fatty liver disease, which results from heavy alcohol use, and non-alcoholic fatty liver disease (NAFLD), which is linked to metabolic risk factors and is more common.

While early stages may not present noticeable symptoms, advanced stages can lead to fatigue, abdominal pain, and an enlarged liver. If left unmanaged, fatty liver can progress to more serious liver conditions, such as fibrosis, cirrhosis, or liver cancer. Treatment focuses on addressing the underlying causes, such as weight loss, dietary changes, increased physical activity, and controlling blood sugar and cholesterol levels.
