Can hepatitis C be deadly?

Some people have few or no symptoms while inflammation continues in the liver. Over time, persistent infection may lead to scarring, reduced liver function, and complications such as fluid accumulation, bleeding, confusion, or liver cancer. This progression is not inevitable for every person, and a symptom alone cannot show how much liver injury is present.

Fatigue is one possible symptom, but it has many causes. More information is available on [Hepatitis C](/conditions/hepatitis-c/) and [Fatigue](/symptoms/fatigue/). Blood tests, examination, and sometimes imaging help clinicians assess the liver.

If you have a positive hepatitis C test or a past exposure, arrange a medical review rather than waiting for symptoms. Your clinician can confirm whether virus is currently present, assess liver health, discuss antiviral treatment, and plan follow-up. Avoid alcohol until you have discussed liver health with a clinician, and do not share items that could carry blood. A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) is a suitable starting point. A [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/) may be part of the evaluation.

Seek urgent medical help for yellowing of the skin or eyes, vomiting blood, black stools, severe abdominal swelling, new confusion, extreme sleepiness, or rapidly worsening illness. These signs can indicate serious liver or gastrointestinal problems and need immediate assessment. Do not wait for a routine appointment if they occur.

Ask whether infection is currently active, whether your liver shows scarring or reduced function, and which treatment options fit your health history. Ask about medicines and supplements to avoid, follow-up testing, and symptoms that should prompt urgent help.
