SymptomsBy Mayo Clinic staff
Signs and symptoms of hepatitis B usually appear about three months after you've been infected and can range from mild to severe. Signs and symptoms of hepatitis B may include:
- Abdominal pain
- Dark urine
- Joint pain
- Loss of appetite
- Nausea and vomiting
- Weakness and fatigue
- Yellowing of your skin and the whites of your eyes (jaundice)
Most infants and children with hepatitis B never develop signs and symptoms. The same is true for some adults.
When to see a doctor
Seek medical care if you have any signs or symptoms that worry you.
If you know you've been exposed to hepatitis B, contact your doctor immediately. A preventive treatment may reduce the risk that the virus will infect your body. But the treatment must be given within 24 hours of exposure to the hepatitis B virus.
