How long can a person live with severe fatty liver disease?

In general, there is no definitive answer regarding the life expectancy of patients with severe fatty liver disease. With active intervention, many can live for a long time; however, if left untreated, the condition may shorten lifespan. If concerned, it is recommended to seek medical advice early. Detailed analysis is as follows:

If patients promptly adjust their lifestyle—such as strictly controlling their diet, maintaining regular exercise—and follow medical advice to take medications that improve liver function, avoid alcohol and hepatotoxic drugs, most cases can achieve disease stabilization or even reversal. Liver function may gradually return to normal, resulting in minimal impact on overall life expectancy and allowing patients to maintain a normal life span.

However, if patients neglect their condition and continue unhealthy habits such as high-fat diets, excessive alcohol consumption, and physical inactivity, severe fatty liver may progress to cirrhosis and potentially lead to serious complications including liver cancer and liver failure. These conditions can significantly impair bodily functions, cause rapid deterioration in health, reduce life expectancy, and in severe cases, become life-threatening.

After diagnosis of severe fatty liver disease, an immediate intervention plan should be established, with regular follow-up tests for liver function and liver imaging. Patients should avoid blindly using health supplements, and all treatments must be conducted under the guidance of qualified physicians to prevent disease progression.
