Hepatitis C usually causes no symptoms at all. When symptoms do show up, they're vague and easy to miss — fatigue, poor appetite, belly pain, or dark urine — and jaundice (yellowing of the skin and eyes) appears in only a minority of new infections. Most people feel fine for years. A blood test, not how you feel, is what confirms it.

The symptoms of hepatitis C, explained
Hepatitis C is a liver disease caused by the hepatitis C virus, which spreads when blood from an infected person enters someone else's bloodstream CDC. The infection is usually silent. Most people who catch it notice nothing, and the symptoms that do appear are the same in men and women, because they come from the liver.
What each symptom is and why it happens:
- Fatigue — a deep, persistent tiredness that rest doesn't fix. It's the most common complaint and also the least specific, so it slips by for years.
- Poor appetite — food stops appealing, sometimes with mild nausea, as the inflamed liver struggles to process fats and toxins.
- Abdominal pain — usually a dull ache or fullness under the right ribs, where the liver sits, as it becomes inflamed and slightly enlarged.
- Dark urine — tea- or cola-colored pee, a sign that bilirubin (a yellow pigment the liver normally clears) is backing up into the blood and spilling into urine.
- Jaundice — yellowing of the whites of the eyes and the skin, again from bilirubin building up. It's the most recognizable sign of hepatitis but the least common.
- Clay-colored stools and itching — when bile flow is disrupted, stool can lose its color and bile salts under the skin can cause generalized itching.
During acute infection — the first six months after exposure — jaundice occurs in only about 20–30% of people, and the milder nonspecific symptoms in roughly 10–20% CDC clinical. The rest feel nothing. Most acute infections then become chronic and lifelong, and chronic hepatitis C often causes no specific symptoms for 20 years or more.
The less obvious signs and where they show up
Because hepatitis C is a liver problem, its signs aren't where people look for an STI. There's no genital sore, no discharge, no rash on the skin you'd associate with a sexually transmitted infection. The clues are systemic, showing up in your energy, your eyes, your urine.
In long-standing chronic infection, the quiet damage accumulates until the liver scars (cirrhosis). That's when the subtler, later signs emerge: swelling in the legs or abdomen as the scarred liver fails to make enough protein, easy bruising as it makes fewer clotting factors, spider-like blood vessels on the skin, and confusion or foggy thinking when toxins the liver should clear reach the brain. These end-stage signs mean the disease has been working silently for a long time. They're a reason to test early.
How soon symptoms appear after exposure
When acute symptoms do occur, the average time from exposure to onset is 2 to 12 weeks, with a full range of 2 to 26 weeks. But that timeline only describes the minority who feel anything at all. For most people there is no symptom milestone to watch for. The virus is present and detectable well before any sign would appear, if one ever does.
This is why timing your test matters more than timing your symptoms. If you've had a specific exposure, the right window for a reliable result is a separate question worth getting right — see our guide on when to test after exposure.
What people commonly mistake hepatitis C for
The early symptoms are so generic that they get blamed on almost anything else first. Fatigue gets chalked up to overwork, stress, or poor sleep. Poor appetite and belly discomfort look like a stomach bug or indigestion. Even jaundice and dark urine can be mistaken for dehydration or another type of hepatitis.
The deeper problem is that the viral hepatitis infections overlap too much to tell apart by sight, and several of them are frequently silent. A test settles which infection it is, if any CDC testing. Overlapping, nonspecific symptoms are why you can't self-diagnose this. A test turns a guess into an answer.
How hepatitis C is confirmed
Confirmation is a two-step blood test: an HCV antibody test first, and if that's positive, an automatic nucleic acid test (NAT) for HCV RNA to confirm a current, active infection. A positive antibody alone only means you were exposed at some point; the RNA test tells you whether the virus is still there. For the full walkthrough of the process and where to do it, see how to get tested.
In practice, screening is recommended broadly: the CDC advises testing all adults 18 and older at least once, and pregnant people each pregnancy, and the USPSTF gives one-time screening for adults aged 18–79 a Grade B recommendation USPSTF. Testing is often free or low-cost at health departments, Planned Parenthood, and Title X clinics, with results usually back in a few days.
Why testing beats waiting for symptoms
The reason to test rather than watch for symptoms is that hepatitis C is now curable for almost everyone. An 8–12-week course of oral direct-acting antiviral (DAA) pills cures more than 95% of people, and that cure is durable, holding in over 99% of those followed for five years AASLD/IDSA. Catching it before it scars the liver is what makes the difference. Learn what treatment involves on our hepatitis c cure page.
| Stage | How long | What you'd likely feel |
|---|---|---|
| Acute | First 6 months after exposure | Usually nothing; sometimes fatigue, poor appetite, belly pain, dark urine, or jaundice |
| Chronic | Can last decades | Often no specific symptoms for 20+ years |
| End-stage (cirrhosis) | After years of silent damage | Swelling, easy bruising, confusion, jaundice |
When to see a clinician
Don't wait to feel sick. Get screened at least once as an adult regardless of symptoms, and sooner if you've ever injected drugs, received blood products long ago, or had a known blood exposure. See a clinician promptly if you notice yellowing eyes or skin, persistent dark urine, unexplained ongoing fatigue, or right-sided abdominal pain — and if you're pregnant, screening is recommended in each pregnancy.
