hepatitis

Also known as hepatitides, acute and subacute liver necrosis, acute and subacute necrosis of liver, acute hepatitis, animal hepatitis, acute and subacute liver necrosis NOS, acute/subac. necrosis of liver, liveritis

Hepatitis is inflammation of the liver tissue. Some people or animals with hepatitis 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. Hepatitis is acute if it resolves within six months, and chronic if it lasts longer than six months. Acute hepatitis can resolve on its own, progress to chronic hepatitis, or (rarely) result in acute liver failure. Chronic hepatitis may progress to scarring of the liver (cirrhosis), liver failure, and liver cancer.

AI overview

Hepatitis is inflammation of the liver tissue that can range from causing no symptoms at all to causing jaundice, poor appetite, vomiting, tiredness, abdominal pain, and diarrhea. It matters because acute hepatitis can sometimes progress to chronic hepatitis or serious complications like liver failure, and chronic hepatitis can eventually lead to cirrhosis, liver failure, and liver cancer.

Hepatitis is most commonly caused by the virus hepatovirus A, B, C, D, and E. Other viruses can also cause liver inflammation, including cytomegalovirus, Epstein–Barr virus, and yellow fever virus. Other common causes of hepatitis include heavy alcohol use, certain medications, toxins, other infections, autoimmune diseases, and non-alcoholic steatohepatitis (NASH). Hepatitis A and E are mainly spread by contaminated food and water. Hepatitis B is mainly sexually transmitted, but may also be passed from mother to baby during pregnancy or childbirth and spread through infected blood. Hepatitis C is commonly spread through infected blood; for example, during needle sharing by intravenous drug users. Hepatitis D can only infect people already infected with hepatitis B.
