What should you know about hepatitis C virus infection?

Hepatitis C is caused by a virus that can inflame the liver. Some people feel well, while others develop tiredness, nausea, poor appetite, discomfort in the upper abdomen, dark urine or yellowing of the eyes and skin. Symptoms alone cannot confirm the infection because other conditions can cause similar changes.

Testing commonly starts with an antibody test. If antibodies are found, a test for virus in the blood helps determine whether infection is current. Liver tests and other assessments help a clinician understand how the liver is coping; a result does not by itself describe the full picture.

Arrange a GP consultation for testing and a treatment discussion. Tell the clinician about past blood exposures, previous results, medicines and supplements. Effective modern treatments are available for hepatitis C, but the choice depends on your results and health history. Avoid sharing needles, razors or toothbrushes, and cover wounds so blood is not shared.

Seek prompt medical advice for new jaundice, persistent vomiting, increasing abdominal swelling, unusual bleeding or severe tiredness. Go to urgent care for confusion, vomiting blood, black stools, severe abdominal pain or a rapidly worsening condition.

Ask which tests you need, whether infection is current, how your liver will be assessed, which treatment options fit your situation, and how to reduce blood exposure to others while testing is underway.
