Non-alcoholic fatty liver disease (NAFLD) is one of the causes of fatty liver, occurring when fat is deposited (steatosis) in the liver due to causes other than excessive alcohol use. The prevalence of nonalcoholic fatty liver disease (NAFLD), a condition once thought to affect mainly overweight postmenopausal women, is increasing among people of all ages. According to a review in the November/December issue of theJournal of Clinical Gastroenterology, NAFLD is believed to be one of the most common forms of liver disease worldwide, and its prevalence is growing in proportion to the rapid rise in obesity. Experts believe this condition may currently affect 20% to 40% of individuals in industrialized Western countries, representing a problem with a wide physical and financial impact.
No standard treatment for nonalcoholic fatty liver disease exists. Doctor may recommend to take vaccinations against hepatitis A and hepatitis B to help protect from viruses that may cause further liver damage. NAFLD typically shows up as an unexpected abnormality in liver function tests, usually the alanine aminotransferase (ALT) test, in people who otherwise feel well. The elevation of this test generally is minor and in younger patients, does not indicate a serious liver condition. However, if the cause of NAFLD, such as obesity or diabetes, is not treated, the condition may progress.
