What Is Non-Alcoholic Fatty Liver Disease

Non-Alcoholic Fatty Liver Disease (NAFLD) refers to the accumulation of fat in the liver that is not caused by alcohol consumption. This condition can lead to liver cell damage and is categorized into different types based on underlying causes and symptoms.

Fatty liver diseases are mainly divided into two categories — alcoholic and non-alcoholic. Alcoholic fatty liver is typically linked to long-term heavy alcohol use. On the other hand, NAFLD occurs in individuals who drink little or no alcohol.

One specific type of NAFLD is acute fatty liver of pregnancy, which is a rare but serious condition that occurs during pregnancy. However, the most common form of NAFLD is further classified based on liver enzyme levels and liver health.

There are two primary forms of NAFLD: simple fatty liver and non-alcoholic steatohepatitis (NASH). In simple NAFLD, fat builds up in the liver but usually does not cause serious damage. In contrast, NASH involves liver inflammation and can lead to liver cell damage and scarring, known as fibrosis.

This condition is more common in women, especially those who are overweight or obese. Sedentary lifestyles, poor dietary habits — such as high intake of sugary and fatty foods — are also major risk factors for developing NAFLD.

If liver enzymes are normal, lifestyle changes such as improved diet and weight loss may be sufficient to manage the condition. Weight management and regular physical activity can help reduce liver fat and improve overall liver health. However, if liver enzyme levels are elevated, it may indicate liver damage, and in such cases, doctors may recommend liver-protecting medications to prevent further harm.

In summary, Non-Alcoholic Fatty Liver Disease is a growing health concern that can often be managed through lifestyle modifications. Early detection and intervention are key to preventing complications such as liver fibrosis or cirrhosis.
