Summary
Hepatitis C is a liver infection caused by the hepatitis C virus, which spreads through contact with infected blood. It can lead to liver inflammation and damage over time, potentially causing serious liver problems if untreated.
Hepatitis C spreads mainly through contact with infected blood, such as sharing needles or receiving blood transfusions before 1992. Risk factors include intravenous drug use, unsterile tattoos or piercings, and being born to a mother with the virus.
Common symptoms include fatigue, jaundice, which is yellowing of the skin, and abdominal pain. Many people have no symptoms for years. If untreated, it can lead to cirrhosis, which is liver scarring, liver failure, or liver cancer.
Hepatitis C is diagnosed through blood tests that detect antibodies to the virus, indicating exposure. If antibodies are present, a follow-up test checks for viral RNA to confirm active infection. Liver function tests assess liver health.
Prevention focuses on avoiding contact with infected blood. Treatment involves direct-acting antivirals, which target the virus's ability to replicate, often clearing the virus in 8 to 12 weeks with a high success rate.
Self-care includes regular medical check-ups, taking prescribed medications, and maintaining a healthy diet rich in fruits, vegetables, and lean proteins. Avoiding alcohol and tobacco is crucial to prevent further liver damage.
Understanding the Disease
What is hepatitis c?
Hepatitis C is a liver infection caused by the hepatitis C virus, which spreads through contact with infected blood. The virus attacks liver cells, leading to inflammation and damage over time. If untreated, it can cause serious liver problems like cirrhosis, which is scarring of the liver, and liver cancer. Hepatitis C can be chronic, meaning it lasts a long time, and can significantly impact health and life expectancy if not managed properly.
What causes hepatitis c?
Hepatitis C is caused by the hepatitis C virus, which enters the bloodstream and infects liver cells, leading to inflammation and damage. The virus spreads mainly through contact with infected blood, such as sharing needles or through blood transfusions before 1992. Risk factors include intravenous drug use, receiving tattoos or piercings with unsterile equipment, and being born to a mother with the virus. The exact reasons why some people clear the virus while others develop chronic infection are not fully understood.
Are there different types of hepatitis c?
Yes, hepatitis C has different types called genotypes, with six main ones identified. Genotype 1 is the most common in the U.S. and often more challenging to treat. Genotypes 2 and 3 are more responsive to treatment. The genotype affects treatment choice and duration but not symptoms or disease severity. Knowing the genotype helps tailor the most effective treatment plan for the individual.
What are the symptoms and warning signs of hepatitis c?
Common symptoms of hepatitis C include fatigue, jaundice, which is yellowing of the skin and eyes, and abdominal pain. Many people have no symptoms for years, making early detection challenging. Symptoms often appear as liver damage progresses. Unique patterns like dark urine and pale stools can help in diagnosis. Regular screening is important, especially for those at risk, to catch the disease before symptoms develop.
What are the five most common myths about hepatitis c?
One myth is that hepatitis C is spread through casual contact, which is false as it spreads through blood. Another is that it always shows symptoms, but many have no symptoms for years. Some believe it can't be cured, yet modern treatments can clear the virus. A myth is that only drug users get it, but anyone can be infected. Lastly, some think it's a death sentence, but with treatment, many live healthy lives.
Which types of people are most at risk for hepatitis c?
Hepatitis C is most prevalent among people born between 1945 and 1965, often called baby boomers, due to past medical practices. Intravenous drug users are also at high risk due to needle sharing. Certain ethnic groups, like African Americans, have higher rates, possibly due to genetic factors and healthcare access. Geographic regions with limited healthcare resources may see higher prevalence due to lack of screening and treatment.
How does hepatitis c affect the elderly?
In the elderly, hepatitis C may progress more rapidly, leading to liver damage sooner than in younger adults. The immune system, which weakens with age, may not fight the virus as effectively. Older adults are more likely to have other health conditions that can complicate hepatitis C management. Early detection and treatment are important to prevent severe liver complications in the elderly.
How does hepatitis c affect children?
Hepatitis C in children often shows fewer symptoms compared to adults. Children may have a higher chance of clearing the virus without treatment. The immune system, which is still developing in children, may respond differently to the virus. Long-term complications like liver damage are less common in children but can occur. Monitoring and early intervention are crucial to prevent future liver issues.
How does hepatitis c affect pregnant women?
In pregnant women, hepatitis C may not show different symptoms compared to non-pregnant adults, but there is a risk of transmitting the virus to the baby. Pregnancy can alter immune function, potentially affecting disease progression. Monitoring and management are crucial to reduce transmission risk and ensure maternal and fetal health. Treatment decisions are carefully considered to balance benefits and risks during pregnancy.
Diagnosis & Monitoring
How is hepatitis c diagnosed?
Hepatitis C is diagnosed through blood tests that detect antibodies to the virus, indicating exposure. If antibodies are present, a follow-up test checks for viral RNA to confirm active infection. Symptoms like fatigue, jaundice, which is yellowing of the skin, and abdominal pain may suggest hepatitis C, but many have no symptoms. Liver function tests and imaging studies like ultrasounds assess liver damage. A liver biopsy, which involves taking a small tissue sample, may be used to evaluate liver health.
What are the usual tests for hepatitis c?
Common tests for hepatitis C include antibody tests, which detect past or present infection, and RNA tests, which confirm active infection by measuring viral load. Liver function tests assess liver health by measuring enzyme levels. Imaging studies like ultrasounds evaluate liver damage. These tests help diagnose the disease, monitor its progression, and guide treatment decisions.
How will I monitor hepatitis c?
Hepatitis C is monitored using blood tests to check liver function and viral load, which is the amount of virus in the blood. Liver function tests, which measure enzymes and proteins in the blood, help assess liver health. Viral load tests show if the virus is present and at what level. Monitoring is typically done every 3 to 6 months, depending on the stage of the disease and treatment status, to ensure the disease is stable or improving.
What are healthy test results for hepatitis c?
Routine tests for hepatitis C include liver function tests and viral load tests. Normal liver enzyme levels, like ALT and AST, indicate healthy liver function. Elevated levels suggest liver inflammation or damage. A viral load test measures the amount of virus in the blood. A high viral load indicates active infection, while an undetectable viral load after treatment suggests the virus is controlled. Regular monitoring helps assess treatment effectiveness and liver health.
Consequences & Complications
What happens to people with hepatitis c?
Hepatitis C can be acute, lasting a few months, or chronic, persisting for years. Most people develop chronic infection, which can lead to liver damage over time. If untreated, it may cause cirrhosis, liver failure, or liver cancer. Available therapies, like antiviral medications, can clear the virus and prevent liver damage. Early treatment significantly improves outcomes and reduces the risk of severe liver complications.
Is hepatitis c lethal?
Hepatitis C can be lethal if untreated, leading to severe liver damage, cirrhosis, or liver cancer. The disease progresses slowly, but chronic infection increases the risk of life-threatening liver complications. Factors like alcohol use, co-infections, and delayed treatment can worsen outcomes. Antiviral treatments can clear the virus, significantly reducing the risk of death and improving liver health. Early diagnosis and treatment are crucial for a positive prognosis.
Will hepatitis c go away?
Hepatitis C progresses slowly, often over decades. It is curable with antiviral medications, which can clear the virus from the body.
