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
  • Fever
  • 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.
