Non-Alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) is a common disorder in which an individual who consumes little or no alcohol accumulates fat around the liver. For most people who have this condition, there are no symptoms or complications. Nonetheless, because the liver is a vital organ, once NAFLD progresses causes liver dysfunction it becomes serious and potentially life-threatening. In fact, cirrhosis resulting from NAFLD is now one of the leading reasons for liver transplants in the United States.

Types of NAFLD

NAFLD is an umbrella term that refers to several forms of fatty liver disease that vary in severity. The three forms of non-alcoholic fatty liver disease are:

  • NAFLD, or simple steatosis
  • Non-alcoholic steatohepatitis, or NASH
  • NASH-related cirrhosis

NASH is a more serious form of NAFLD, characterized by excessive fat accumulations that result in inflammation and the development of scar tissue in the liver. In NASH-related cirrhosis, the most dangerous form of NAFLD,the condition progresses to fibrosis, cirrhosis and, potentially, liver failure.

Risk Factors for NAFLD

NAFLD, currently considered by many physicians as part of metabolic syndrome, has been linked to a wide range of diseases conditions, most especially obesity and insulin resistance. Poor diet, particularly a diet too high in fat, has also been linked to NAFLD. Other health disorders associated with NAFLD include:

  • High cholesterol
  • Sleep apnea
  • Hypothyroidism
  • Polycystic ovary syndrome

There also appears to be a genetic component to this condition.

Symptoms of NAFLD

Even more serious forms of NAFLD typically result in few symptoms. When symptoms do develop, they may include some of the following:

  • Loss of appetite, nausea, weight loss
  • Weakness, fatigue, mental confusion
  • Abdominal pain, blackened stools
  • Jaundice
  • Itching
  • Edema or ascites (swelling of legs or abdomen)
  • Development of spider veins

In many, or even most, cases, NAFLD patients are asymptomatic and the disease is discovered incidentally through routine diagnostic tests.

Diagnosis of NAFLD

NAFLD may be suspected if a blood test shows elevated liver enzymes. To confirm this diagnosis, a series of tests are conducted that may include, further blood tests, imaging tests such as an ultrasound or an MRI or CT scan. A liver biopsy may be necessary to differentiate the mildest form of NAFLD from those involving inflammation or scarring.

Treatment of NAFLD

Treatment methods of mild NAFLD are also the methods for preventing the development of the condition. These include lifestyle changes such as:

  • Eating a healthy diet
  • Getting to a healthy weight
  • Having an exercise routine
  • Avoiding smoking and drinking alcohol
  • Controlling related disorders like diabetes and high cholesterol
  • Avoiding any unnecessary prescription medications

Even though NAFLD is not caused by excessive alcohol use, patients are advised to refrain from drinking alcoholic beverages which can exacerbate the condition. Where morbid obesity is a factor, patients may require bariatric surgery. Once liver inflammation or scarring is apparent, the disease may require liver transplantation.
