Will you know if you have hepatitis B?

Not necessarily. You may have hepatitis B and not have any symptoms. You can still spread the virus to others even if you don't have symptoms. Some people who do have symptoms might have the following:

• Yellowing skin or eyes (or jaundice)
• Not feeling hungry
• Feeling tired
• Muscle, joint, or stomach pain
• Stomach upset, diarrhea, or vomiting
