Fatty Liver Disease Is Not Hepatitis But Can Lead To Liver Inflammation

Fatty liver disease is not caused by a virus and therefore is not classified as viral hepatitis. However, it can lead to inflammation of the liver if left unmanaged. In its early stage, known as simple fatty liver or non-alcoholic fatty liver disease (NAFLD), fat accumulates in the liver cells without causing significant damage, inflammation, or scarring. Most patients with this condition can reverse the fat buildup through lifestyle changes such as eating healthier and losing weight. At this stage, medication is typically not required.

If the condition progresses, however, it can develop into non-alcoholic steatohepatitis (NASH), a more severe form that involves liver inflammation and damage. This stage is marked by elevated liver enzymes and signs of liver cell injury. Symptoms may include fatigue, weight loss, and discomfort in the upper right side of the abdomen. If untreated, NASH can lead to fibrosis or even cirrhosis, where healthy liver tissue is replaced by scar tissue.

Early detection and intervention are crucial to prevent serious complications. Doctors often recommend a combination of diet control, physical activity, and in some cases, medication to manage liver damage and reduce fat accumulation. Maintaining a healthy weight and avoiding excessive alcohol intake are key preventive measures. It's important for individuals at risk—such as those with obesity, diabetes, or high cholesterol—to monitor their liver health regularly.
