Clinical Information
  • (hep-a-tye-tis) disease of the liver causing inflammation. Symptoms include an enlarged liver, fever, nausea, vomiting, abdominal pain, and dark urine.
  • Disease of the liver causing inflammation. Symptoms include an enlarged liver, fever, nausea, vomiting, abdominal pain, and dark urine.
  • Hepatitis. Inflammation of the liver; usually from a viral infection, but sometimes from toxic agents. Previously endemic throughout much of the developing world, viral hepatitis now ranks as a major public health problem in industrialized nations. The three most common types of viral hepatitis -- a, b, and c -- afflict over 500,000 people in the United States Each year, and millions worldwide. Hepatitis b alone ranks as the ninth leading killer in the world. Hepatitis a, an rna enterovirus, spread by contact with fecal matter or blood, most often through ingestion of contaminated food. Rarely fatal, it cannot be treated except by bed rest for 1 -- 4 weeks, during which time no alcohol should be consumed. It may recur after 3 months. Hepatitis b is shed through blood, semen, vaginal secretions, and saliva approximately 4 -- 6 weeks after symptoms develop; the virus may take up to 6 months to incubate, and people may also become asymptomatic carriers. Hepatitis b may heal slowly, and is a leading cause of chronic liver disease and cirrhosis. Effective vaccines exist, but it is the fastest spreading form of the disease in the United States, with some 300,000 cases reported annually. Rates were up 80% from 1981 -- 1986 among iv drug users and up 38% during the same period among heterosexuals; among homosexuals, previously a high-risk group, rates held stable. Hepatitis c, infecting about 150,000 americans annually, remains in the blood for years and accounts for a large percentage of cirrhosis, liver failure, and liver cancer cases. Its main mode of transmission is through blood transfusion, and possibly sexual intercourse. Types d and e are less frequently seen in the United States (sted98)
  • Inflammation of the liver and liver disease involving degenerative or necrotic alterations of hepatocytes.
  • Inflammation of the liver.
  • Inflammation of the liver; usually from a viral infection, but sometimes from toxic agents.
  • Your liver helps your body digest food, store energy and remove poisons. Hepatitis is a swelling of the liver that makes it stop working well. It can lead to scarring, called cirrhosis, or to cancer.viruses cause most cases of hepatitis. The type of hepatitis is named for the virus that causes it; for example, hepatitis a, hepatitis b or hepatitis c. Drug or alcohol use can also lead to hepatitis. In other cases, your body mistakenly attacks its own tissues. You can help prevent some viral forms by getting a vaccine. Sometimes hepatitis goes away by itself. If it does not, it can be treated with drugs. Sometimes hepatitis lasts a lifetime.some people who have hepatitis have no symptoms. Others may have

    • nausea and vomiting
    • diarrhea
    • dark-colored urine and pale bowel movements
    • stomach pain
    • jaundice, yellowing of skin and eyes
