Which disease does hepatitis B virus cause?

The virus infects liver cells and may trigger inflammation. Some infections settle, while others remain and require ongoing monitoring. A person may feel entirely well, or may notice fatigue, nausea, poor appetite, discomfort in the upper abdomen, yellowing of the eyes or skin, or dark urine. These symptoms are not specific to hepatitis B and cannot establish the diagnosis without testing.

Long-standing infection can require regular review because liver inflammation may not cause early symptoms. Blood tests can identify hepatitis B markers and a Liver Function Test can help assess liver irritation. A clinician combines these findings with your history.

Book a medical appointment to discuss testing, vaccination history and any possible exposure. Keep follow-up visits even if you feel healthy. Avoid sharing razors, toothbrushes or needles, cover open wounds, and tell healthcare professionals about the result or concern.

Hepatitis B Vaccination can prevent infection in people who are not protected. If infection is confirmed, a clinician will decide whether observation, repeat testing, specialist input or treatment fits your results. Do not take someone else’s medicine.

Arrange prompt care for persistent fatigue, dark urine, yellowing, abdominal swelling or repeated vomiting. Seek urgent help for confusion, severe drowsiness, unusual bleeding or rapidly worsening symptoms. A recent blood or body-fluid exposure also deserves prompt advice about prevention.

Ask which tests confirm hepatitis B, whether the infection appears recent or long-standing, and what your liver results show. Should you have repeat blood work or specialist review? Are close contacts protected by vaccination? What symptoms should trigger urgent care?
