Hepatitis B

Hepatitis B is a viral liver infection spread through blood and body fluids. Many adults clear it, but some develop a long-term infection that can harm the liver. A safe vaccine prevents it, and long-term cases are managed with antiviral medicine and monitoring.

• Fatigue
• Nausea and poor appetite
• Jaundice (yellow eyes/skin)
• Dark urine

When to see a doctor

FAQs
