The more severe form of nonalcoholic fatty liver disease is called nonalcoholic steatohepatitis (NASH). Nonalcoholic steatohepatitis causes the liver to swell and become damaged. Nonalcoholic steatohepatitis tends to develop in people who are overweight or obese, or have diabetes, high cholesterol or high triglycerides. However, some people have nonalcoholic steatohepatitis even if they do not have any risk factors.

Most people with nonalcoholic steatohepatitis are between the ages of 40 and 60 years. It is more common in women than in men. NASH often has no symptoms and people can have nonalcoholic steatohepatitis for years before symptoms occur.

Nonalcoholic steatohepatitis is one of the leading causes of cirrhosis in adults in the United States. Up to 25% of adults with nonalcoholic steatohepatitis may have cirrhosis.

Healthy Liver






Cancerous Liver


The Healthy Liver

A healthy liver has the amazing ability to grow back, or regenerate when damaged.


When treated successfully at this stage, there’s a chance your liver can heal itself.

Liver Cancer

Cirrhosis and hepatitis B are leading risk factors for primary liver cancer.

Liver Failure

Liver failure is a life-threatening condition that demands urgent medical care.

There are many different types of liver disease. But no matter what type you have, the damage to your liver is likely to progress in a similar way.

Whether your liver is infected with a virus, injured by chemicals, or under attack from your own immune system, the basic danger is the same – that your liver will become so damaged that it can no longer work to keep you alive.

Cirrhosis, liver cancer, and liver failure are serious conditions that can threaten your life. Once you have reached these stages of liver disease, your treatment options may be very limited.

That’s why it’s important to catch liver disease early, in the inflammation and fibrosis stages. If you are treated successfully at these stages, your liver may have a chance to heal itself and recover.

Talk to your doctor about liver disease. Find out if you are at risk or if you should undergo any tests or vaccinations.
