How does hepatitis C affect life expectancy?

Hepatitis C can remain quiet while inflammation gradually scars the liver. Some people have little lasting damage, while others develop advanced scarring, liver failure, or liver cancer. Outlook depends on the amount of scarring, other liver conditions, alcohol use, metabolic health, and whether the infection is cleared.

Clearing the virus stops ongoing infection but does not erase established scar tissue. Follow-up may still be needed when significant scarring is present. Feeling well is reassuring but cannot show how much liver damage exists; fatigue can also have causes unrelated to hepatitis C.

Arrange testing after a possible exposure or an unexpected liver test result. If hepatitis C is confirmed, discuss antiviral treatment and an assessment of liver scarring. Avoid alcohol or ask a clinician what is safe for you, check medicines and supplements before taking them, and keep appointments for monitoring.

A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can organise initial assessment and follow-up. A [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/) provides information about liver activity, while other assessments may be needed to understand scarring.

Seek urgent medical help for confusion, vomiting blood, black stools, severe abdominal swelling, marked yellowing of the skin or eyes, or sudden severe weakness. Contact your clinician promptly after a positive hepatitis C test, even without symptoms, so liver health and treatment can be reviewed.

Ask how much liver scarring is present, whether treatment can clear the virus, which medicines or supplements to avoid, what monitoring is needed after treatment, and which warning symptoms require emergency care.
