Hepatitis b

From WikiMD's Wellness Encyclopedia

Hepatitis B is a virus that infects the liver and can cause a range of health problems, including liver disease and liver cancer. It is spread through contact with the blood or other body fluids of an infected person.

Causes[edit | edit source]

Hepatitis B is caused by the hepatitis B virus. This virus is spread through direct contact with infected blood or body fluids. This can occur through sexual contact, sharing needles, syringes, or other drug-injection equipment, or from mother to baby at birth.

Symptoms[edit | edit source]

Many people with hepatitis B do not have symptoms and do not know they are infected. If symptoms occur, they can include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain, and jaundice.

Diagnosis[edit | edit source]

Hepatitis B is diagnosed with a blood test. The test looks for parts of the virus (antigens) in the blood, as well as antibodies produced in response to the virus.

Treatment[edit | edit source]

There is no specific treatment for acute hepatitis B. However, chronic hepatitis B can be treated with antiviral medications. This can slow the progression of cirrhosis, reduce incidence of liver cancer and improve long term survival.

Prevention[edit | edit source]

The best way to prevent hepatitis B is by getting the hepatitis B vaccine. The vaccine is safe and effective and is usually given as 3-4 shots over a six-month period.
