About Fatty Liver and Steatohepatitis
Fatty liver is the build-up of fat in the liver cells. Although fat in the liver usually causes no damage by itself, it can be a sign of a more harmful condition. Fatty liver may be associated with or lead to inflammation of the liver, known as steatohepatitis, which can cause scarring and hardening of the liver. Extensive scarring is called cirrhosis, and is considered a very serious condition.
Frequently Asked Questions about Fatty Liver and Steatohepatitis
Q. What causes fatty liver?
A. The liver plays an important role in breaking down fats in the body. Fat accumulates when this process malfunctions or when conditions such as diabetes mellitus, high blood triglycerides or heavy alcohol use are present. The accumulation can also be caused by tuberculosis and malnutrition, excess vitamin A or use of certain drugs, such as valproic acids or corticosteroids. Pregnancy can also cause fatty build up.
Q. How do I know if I have fatty liver?
A. There are usually no noticeable symptoms. In fact, fatty liver is frequently uncovered during a routine physical examination or while your physician is evaluating you for other illnesses.
Q. How is fatty liver diagnosed?
A. To be certain of a diagnosis of fatty liver the physician may recommend a liver biopsy during which a small piece of liver tissue is removed with the needle and examined under a microscope.
Q. What are the complications from fatty liver?
A. Steatohepatitis, the inflammation of the liver due to fat accumulation, is one possible complication and signals serious liver damage. It occurs frequently in people who are significantly overweight or have experienced rapid weight loss.
Q. What is the treatment for fatty liver and steatohepatitis?
A. In most instances, treatment of fatty liver and steatohepatitis requires control of the underlying conditions. This may include reduction of high blood triglycerides, controlling diabetes or eliminating the use of alcohol. In some cases, surgical reversal of intestinal bypass for obesity is required.
