If I have hepatitis B, what should I do?

Hepatitis B is a viral infection that affects the liver. Some infections settle after a short illness, while others persist and need continuing review. A positive test does not by itself show how active the infection is or how much the liver has been affected. Blood tests can assess viral markers and liver enzymes; an examination or scan may also be considered.

Possible symptoms include tiredness, nausea, discomfort under the ribs, yellowing of the skin or eyes, and dark urine. Some people have no symptoms, so follow-up matters even when you feel well.

Book an appointment with a doctor who can review the result and plan monitoring. Avoid sharing razors, toothbrushes, needles, or anything that may carry blood. Cover cuts, and tell sexual partners so they can discuss testing and vaccination. Do not donate blood, and ask before taking medicines, supplements, or herbal products because some can strain the liver. Limit alcohol while your liver is being assessed.

Ask about a Liver Function Test and whether household or sexual contacts need vaccination. The Hepatitis B Vaccination page explains how prevention can protect people who have not been infected.

Seek urgent medical help for confusion, severe sleepiness, repeated vomiting, intense abdominal pain, yellowing that is worsening, unusual bleeding, or difficulty staying awake. Contact a clinician promptly if you notice dark urine, marked fatigue, or new swelling, even if the symptoms seem mild. A Hepatitis B clinician can explain which changes require same-day assessment.

Ask whether the infection is recent or longstanding, which blood tests are needed, how often your liver should be checked, whether treatment is appropriate, and how to reduce transmission at home.
