Further Outpatient Care
All patients with chronic liver disease should be tested for hepatitis A total antibodies and vaccinated if needed. Physicians should also consider testing for hepatitis B surface antibody and vaccinating in the appropriate clinical situation (ie, life expectancy, >20 y).
All patients with chronic liver disease are at risk of liver disease progression.
Patients should be educated to avoid alcohol and other hepatotoxic substances. If patients have a liver insult from another liver problem, they may have a longer recovery than a person without fatty liver disease.
Patients with fatty liver disease should be seen regularly by a primary care physician who may be able to detect disease progression through physical examination findings (eg, spider telangiectasia, palmar erythema, splenomegaly), laboratory findings (eg, decreasing platelets, elevated bilirubin, decreasing albumin), patient complaints (eg, encephalopathy, ascites, fatigue), or incidental imaging study findings (eg, cirrhotic liver, splenomegaly, varices, ascites).
Deterrence/Prevention
Fatty liver disease can be prevented in the most patients by taking the following measures:
- Eating appropriate portions
- Eating healthy choices
- Exercising regularly
Complications
- Steatohepatitis may progress to cirrhosis, with complications that include variceal bleeding, ascites, encephalopathy, and liver failure.
- The rate of progression appears to be worse if more than one liver disease (eg, alcoholic liver disease, chronic viral hepatitis) is present. Also, the lack of control of diabetes and hypertriglyceridemia appears to predict worse fibrosis.[58, 59, 60, 61]
- The rate of formation of hepatocellular carcinoma appears to be the same as with other forms of liver disease.[62]
Prognosis
- Steatosis may be reversible with weight loss and/or stopping alcohol use.
- Of patients with steatohepatitis, 10% will progress to fibrosis and cirrhosis. This rate is the same as that of alcoholics progressing to cirrhosis.
- Long-term natural history studies of patients with NAFLD who undergo repeat biopsies have shown that 30% progress, 30% remain stable, and 30% improve over a 3-year period without pharmacologic intervention.[63]
- Abnormal glucose tolerance testing is an independent risk factor for progression of NASH.[64]
Patient Education
- For excellent patient education resources, visit eMedicine's Liver, Gallbladder, and Pancreas Center and Hepatitis Center. Also, see eMedicine's patient education article Cirrhosis.
- The American Diabetes Association has excellent dietary and lifestyle advice for patients who would like to lose weight and to make better lifestyle choices.
- Nutrition and lifestyle education are the mainstay of therapy. Ideally, during every health care provider encounter, the issues of food choices, food portions, and exercise, including weight-bearing exercise, should be emphasized and reviewed.
