Can hepatitis B infection cause liver cirrhosis?

Cirrhosis develops when ongoing injury replaces healthy liver tissue with scar tissue. It does not happen to everyone with hepatitis B, and timely monitoring and antiviral treatment can help limit additional damage.

Hepatitis B infects liver cells. When infection remains active, the immune response and repeated healing can create fibrosis. As fibrosis becomes extensive, the liver's structure changes and blood has more difficulty flowing through it; this advanced scarring is cirrhosis. A person may feel well while damage is developing, so symptoms alone cannot show how healthy the liver is.

Arrange follow-up with a clinician experienced in hepatitis care. Blood tests can assess viral activity and liver function, while imaging or a liver-stiffness assessment can look for scarring. If antiviral medicine is prescribed, take it consistently and do not stop without clinical advice, because viral activity can rebound. Avoid alcohol and check before using herbal remedies, supplements, or medicines that may affect the liver. Household and sexual contacts can ask about hepatitis B testing and vaccination.

Seek urgent medical care for vomiting blood, black stools, new confusion, marked drowsiness, severe abdominal swelling, or difficulty breathing. Contact a clinician promptly for yellowing of the eyes or skin, increasing leg swelling, dark urine, persistent vomiting, or worsening weakness. These features can signal that the liver is struggling or that cirrhosis has developed a complication.

Ask whether your hepatitis B is active, whether you have fibrosis or cirrhosis, and which tests should be repeated. Also discuss whether antiviral treatment is appropriate, which medicines or supplements to avoid, and whether you need ongoing liver imaging.
