<unk>  is inflammation of the liver tissue. Some people or animals with<unk>  have no symptoms, whereas others develop yellow discoloration of the skin and whites of the eyes (jaundice), poor appetite, vomiting, tiredness, abdominal pain, and diarrhea.<unk>  is acute if it resolves within six months, and chronic if it lasts longer than six months. Acute<unk>  can resolve on its own, progress to chronic<unk> , or (rarely) result in acute liver failure. Chronic<unk>  may progress to scarring of the liver (cirrhosis), liver failure, and liver cancer.<unk>  is most commonly caused by the viruses<unk>  A, B, C, D, and E. Other causes include heavy alcohol use, certain medications, toxins, other infections, autoimmune diseases, and non-alcoholic steatohepatitis (NASH).<unk>  A and E are mainly spread by contaminated food and water.<unk>  B is mainly sexually transmitted, but may also be passed from mother to baby during pregnancy or childbirth and spread through infected blood.<unk>  C is commonly spread through infected blood such as may occur during needle<unk> aring by intravenous drug users.<unk>  D can only infect people already infected with<unk>  B.<unk>  A, B, and D are preventable with immunization. Medications may be used to treat chronic viral<unk> . Antiviral medications are recommended in all with chronic<unk>  C, except those with conditions that limit their life expectancy. There is no specific treatment for NASH; however, physical activity, a healthy diet, and weight loss are recommended. Autoimmune<unk>  may be treated with medications to suppress the immune system. A liver transplant may be an option in both acute and chronic liver failure. Worldwide in 2015,<unk>  A occurred in about 114 million people, chronic<unk>  B affected about 343 million people and chronic<unk>  C about 142 million people. In the United States, NASH affects about 11 million people and alcoholic<unk>  affects about 5 million people.<unk>  results in more than a million deaths a year, most of which occur indirectly from liver scarring or liver cancer. In the United States,<unk>  A is estimated to occur in about 2,500 people a year and results in about 75 deaths. The word is derived from the Greek hêpar (), meaning "liver", and -itis (), meaning "inflammation".
