大三美羊羊

Definition
Hepatitis B is inflammation (irritation and swelling) of the liver due to the hepatitis B virus (HBV).

Symptoms
Many people who have chronic hepatitis B have few or no symptoms. They may not even look sick. As a result, they may not know they are infected. However, they can still spread the virus to other people.

Symptoms may not appear for up to 6 months after the time of infection. Early symptoms may include:

•Appetite loss
•Fatigue
•Low-grade fever
•Muscle and joint aches
•Nausea and vomiting
•Yellow skin and dark urine due to jaundice
People with chronic hepatitis may have no symptoms, even though gradual liver damage may be occurring. They may have some or all of the symptoms of acute hepatitis.
