Hepatitis B is a serious viral liver infection that is caused by the hepatitis B virus (HBV).
The hepatitis B virus can be passed from person to person through various ways, including:
- Sexual contact
- Sharing of needles
- Accidental needlesticks
- Pregnant person to newborn
There are two types of hepatitis B: acute hepatitis B and chronic hepatitis B.
Acute hepatitis B is a short-term illness that occurs within the first six months after being exposed to the hepatitis B virus.
Chronic hepatitis B is a longer-term illness that lasts more than six months after exposure.
Most adults who develop hepatitis B will make a full recovery even if they have severe symptoms. However, infants and children are more likely to develop chronic hepatitis B infection.
Hepatitis B symptoms can range from mild to serious and usually start about one to four months after being infected with the hepatitis B virus, but can be noticeable as early as two weeks after the initial infection. Symptoms of hepatitis B include:
- Abdominal pain
- Dark urine
- Fever
- Joint pain
- Nausea and vomiting
- Fatigue and weakness
- Loss of appetite
- Jaundice
Although anyone can get hepatitis B, certain people have an increased risk of infection if they:
- Have sexually transmitted diseases such as HIV
- Take immunosuppressants that keep the immune system from mistakenly attacking healthy tissue
- Are currently receiving dialysis treatment
- Have another type of liver disease
An acute and chronic hepatitis B infection can cause several complications, including:
- Acute liver failure
- Chronic liver failure
- Cirrhosis of the liver
- Liver cancer
- Reactivated hepatitis B
- Hepatitis D
A healthcare provider can diagnose hepatitis B by asking about your symptoms and performing a physical exam. They will also ask if there is any family history of liver disease. They may ask:
- If your work exposes you to the virus
- If you use any intravenous (IV) drugs
- If you have unprotected sex with anyone who may have hepatitis B
A healthcare provider may also perform tests to help diagnose hepatitis B, including:
- Blood tests
- Imaging tests such as an elastography
- Liver biopsy
Treatment for hepatitis B is dependent on your situation. A healthcare provider may prescribe prophylactic treatment, which is medication to prevent a disease, if you were exposed to the virus within the past 24 hours. Medications for prophylactic treatment include:
- Hepatitis B vaccination
- Hepatitis B immune globulin (HBIG)
Acute hepatitis does not have a specific treatment. A healthcare provider may prescribe IV fluids to prevent dehydration if you have been vomiting or experiencing diarrhea.
Treatment for chronic hepatitis B varies, as it depends on your symptoms and overall health. Treatment options can include:
- Monitoring your overall health
- Medications such as antiviral drugs or immunomodulators
- Surgery to remove part of your liver if hepatitis B causes cancer, or a liver transplant if your whole liver must be removed
The best way to reduce the risk of or prevent a hepatitis B infection is to get vaccinated. It takes three doses of the hepatitis B vaccine, administered over six months, to achieve complete protection from infection. You can also reduce your risk by practicing safe sex and needle use and not sharing personal items.
