- Nonalcoholic steatohepatitis (NASH) is fat in the liver, with inflammation and damage. - NASH occurs in people who drink little or no alcohol and affects 2 to 5 percent of Americans, especially people who are middle-aged and overweight or obese. - NASH can occur in children. - People who have NASH may feel well and may not know that they have a liver disease. - NASH can lead to cirrhosis, a condition in which the liver is permanently damaged and cannot work properly. - Fatigue can occur at any stage of NASH. - Weight loss and weakness may begin once the disease is advanced or cirrhosis is present. - NASH may be suspected if blood tests show high levels of liver enzymes or if scans show fatty liver. - NASH is diagnosed by examining a small piece of the liver taken through a needle, a procedure called biopsy. - People who have NASH should reduce their weight, eat a balanced diet, engage in physical activity, and avoid alcohol and unnecessary medications. - No specific therapies for NASH exist. Experimental therapies being studied include antioxidants and antidiabetes medications.
