Fatty liver disease

Fatty liver disease: Introduction

Fatty liver disease, also called hepatic steatosis, is a type of liver disease and is most commonly the result of excessive alcohol consumption, including alcoholism or alcohol dependence. This is called alcoholic fatty liver disease, which is the most common form of alcoholic liver disease. Alcoholic fatty liver disease is often the first stage in developing or is associated with more serious diseases, such as alcoholic cirrhosis of the liver or alcoholic hepatitis.

Less commonly, fatty liver disease that is not related to alcohol consumption can occur. This is called nonalcoholic fatty liver disease. Nonalcoholic fatty liver disease is usually diagnosed in people who are obese and/or have insulin resistance.

Fatty liver disease results in the accumulation of fat in the liver, leading to an enlarged liver. If alcohol consumption or other causes continue, damage done to the liver due to fatty liver disease can progress, lead to, and/or occur with the development of other related alcoholic liver diseases or liver diseases. Most commonly these include alcoholic cirrhosis of the liver and alcoholic hepatitis, which can result in permanent damage and scarring of the liver. These and other liver disease can critically affect the liver's ability to do its job to fight infection, stop bleeding, clear the blood of toxins, store energy, produce healthy blood, digest food and remove waste.

There are often no symptoms of fatty liver disease, especially in its early stage before more serious liver diseases develop. An enlarged liver may be present, but there generally is no abdominal pain or liver tenderness upon examination. For more information on symptoms and complications, refer to symptoms of fatty liver.

Making a diagnosis of fatty liver disease includes performing a complete medical evaluation and history and physical examination. This includes questioning about the history of alcohol use. An abdominal examination may reveal a liver that is enlarged and smooth. The liver is generally not tender or painful when pressed or palpated.

Diagnostic testing includes liver function tests. These are blood tests that can reveal abnormal functioning of the liver. Imaging tests that create a picture of the liver may include an ultrasound, CT, and/or a nuclear liver scan. Diagnostic testing also includes blood sugar testing and monitoring to help determine if insulin resistance is present.

In some cases, a surgical procedure called a laparoscopy may also be performed. This procedure allows the physician to visualize the liver using a special lighted instrument, called a laparoscope. The laparoscope is inserted through a small incision in the abdomen and moved into place to view the liver and send pictures to a computer screen. This procedure is minimally invasive and may include taking a small sample of liver tissue, called a biopsy, to examine for signs of liver damage. A liver biopsy may also be performed by inserting a long needle through the abdomen into the liver. This test is generally performed in cases where it is suspected that fatty liver disease has progressed beyond the very earliest stage and/or symptoms of other more advanced forms of liver disease are present.

It is possible that a diagnosis of fatty liver disease can be missed or delayed because there are often no symptoms in the early stages and for other reasons. For more information on misdiagnosis, refer to misdiagnosis of fatty liver disease.

Fatty liver disease in its early stage is potentially reversible and curable if diagnosed and treated promptly. Treatment includes lifestyle changes, treating alcoholism or alcohol dependence, and possibly medication. For more information on treatment, refer to treatment of fatty liver disease. ...more »

Fatty liver disease: Fatty liver disease can range from fatty liver alone (steatosis) to fatty liver associated with inflammation (steatohepatitis). This condition can occur with the use of alcohol (alcohol-related fatty liver) or in the absence of alcohol (nonalcoholic fatty liver disease [NAFLD]). More detailed information about the symptoms, causes, and treatments of Fatty liver disease is available below.

Fatty liver disease: Symptoms

Many people with fatty liver disease experience no symptoms, especially in the early stage of the disease. The liver may be enlarged, but this is generally unnoticeable by the individual. An enlarged liver may be felt by a health care practitioner when palpating or pressing on the abdomen. An enlarged liver due to fatty liver disease is generally smooth, and there usually is ...more symptoms »

Fatty liver disease: Treatments

Treatment plans for fatty liver disease are individualized to best fit the patient's age, medical history, and underlying cause of fatty liver disease. The goal of treatment is to reverse, stop or slow the progression of damage to the liver and minimize and quickly treat any additional related diseases and complications, such as alcoholic hepatitis and alcoholic cirrhosis of the ...more treatments »

Fatty liver disease: Misdiagnosis

A diagnosis of fatty liver disease may be overlooked or delayed because there may be no symptoms in early stages. Some people may also delay treatment because they fear or are in denial of a diagnosis of the some underlying causes of fatty liver diseases, including alcoholism or alcohol dependence. ...more misdiagnosis »
