Hepatitis B: Introduction
Hepatitis B is a form of hepatitis, a group of serious diseases that cause inflammation of the liver. Hepatitis B is an infectious form of hepatitis that is caused by the hepatitis B virus. Hepatitis B is one of the most common forms of hepatitis.
The liver is a vital organ, and normal functioning of the liver is crucial to health and life. Hepatitis B can result in complications of the liver, such as cirrhosis of the liver and liver failure. This reduces liver's ability to do its vital job in helping the body to fight infection, stop bleeding, clear the blood of toxins, store energy, produce healthy blood, digest food, and remove waste. Having hepatitis B also increases the risk of developing liver cancer.
The hepatitis B virus is spread by having contact with the blood, semen, and vaginal secretions of a person infected with the hepatitis B virus. High risk activities include having unprotected sexual activity, having multiple sexual partners, sharing contaminated needles, or getting a tattoo or body piercing using unsterilized needles. A baby born vaginally to an infected woman can also contract an infection of hepatitis B. Any person who comes into frequent contact with blood, such as healthcare workers, are also at risk for hepatitis B.
In some people with early hepatitis B infection, there may be no symptoms. General symptoms common to hepatitis B include flu-like symptoms, fever, fatigue, muscle aches and jaundice, a yellowing of the skin and whites of the eyes. Complications can be serious, even life-threatening, and include the development of cirrhosis and liver failure. For more information about additional symptoms and complications, refer to symptoms of hepatitis B.
Making a diagnosis of hepatitis B includes performing a complete medical evaluation and history and physical examination. This includes questions about risk factors for contracting hepatitis B, such as having unprotected sex, sharing needles, or having tattoos or body piercings that were made with unsterilized needles.
Diagnostic blood tests include tests that can check for the antibodies that the body makes to fight hepatitis B and the hepatitis B surface antigen test. Blood tests can also be done that help to determine how likely it is that a person is infectious and will spread hepatitis B.
Liver function tests are blood tests that can help to determine the level of severity of hepatitis B by checking level of functioning of the liver and if there is any damage to the liver. Imaging tests that create a picture of the liver include an ultrasound, CT, and/or a nuclear liver scan.
It is possible that a diagnosis of hepatitis B can be missed or delayed because symptoms can be vague or there may be no symptoms in some people. In addition, symptoms of hepatitis B can be similar to symptoms of other diseases and conditions. For more information about diseases and conditions that can mimic hepatitis B, refer to misdiagnosis of hepatitis B.
There is no cure for Hepatitis B. Treatment includes rest, ensuring good nutrition, and antiviral medications in some cases. For serious cases I which liver damage or liver failure has occurred, hospitalization may be necessary. Treatment in the hospital may include medications and other diagnostic testing and liver transplant. For more information on treatment, refer to treatment of hepatitis B. ...more »
