What is Hepatitis C

Hepatitis C is a serious viral infection that primarily affects the liver. While it may remain unnoticed in its early stages, untreated hepatitis C can lead to chronic liver disease, cirrhosis, and even liver cancer over time. Understanding this condition is crucial because with proper medical care, hepatitis C is now curable in most people.

Caused by the hepatitis C virus (HCV), this infection is primarily spread through contact with contaminated blood. While it may start as a short-term illness, in the majority of cases, it becomes chronic, potentially leading to serious complications such as liver fibrosis, cirrhosis, liver failure, and liver cancer if left untreated.

What is Hepatitis C?

Hepatitis C is caused by the hepatitis C virus (HCV). It is one of several types of viral hepatitis, including hepatitis A, B, D, and E. However, hepatitis C is particularly concerning because it often becomes a chronic condition if left untreated.

Once infected, the virus attacks liver cells, causing inflammation and damage. Unlike hepatitis A, which usually resolves on its own, hepatitis C tends to linger in the body and gradually impairs liver function. In fact, more than half of people infected with HCV develop chronic hepatitis C, which can persist for decades.

Causes and Transmission of Hepatitis C

The primary cause of hepatitis C is exposure to the blood of an infected person. The virus is bloodborne, which means it spreads mainly through activities that involve direct blood-to-blood contact.

Common Modes of Transmission Include :-

1. Sharing needles or syringes during intravenous drug use.

2. Blood transfusions or organ transplants before 1992, when HCV screening was not standard.

3. Accidental needle-stick injuries among healthcare workers.

4. Unsterilized medical or tattoo equipment.

5. In rare cases, sexual transmission or mother-to-child transmission during childbirth.

Hepatitis C does not spread through casual contact like hugging, kissing, or sharing food and drinks.

Symptoms of Hepatitis C

Hepatitis C is often called a “silent infection” because many individuals do not experience noticeable symptoms until the liver is significantly damaged. When symptoms do appear, they may vary from mild to severe.

Early Symptoms (Acute Phase) :-

1. Fatigue

2. Fever

3. Nausea or vomiting

4. Dark urine

5. Jaundice (yellowing of the skin or eyes)

6. Abdominal pain, especially in the upper right side

7. Joint or muscle pain

These symptoms typically occur within 2 to 12 weeks after exposure. However, not everyone in the acute phase will notice them.

Chronic Phase :-

Over time, chronic hepatitis C can lead to liver fibrosis, cirrhosis, liver failure, or hepatocellular carcinoma (a type of liver cancer). Chronic symptoms may include :-

1. Persistent fatigue

2. Loss of appetite

3. Unexplained weight loss

4. Confusion or memory issues (hepatic encephalopathy)

5. Swelling in the legs or abdomen

Because the disease can progress silently, regular screening is essential for at-risk individuals.

Who is at Risk?

Certain populations are more likely to be exposed to the hepatitis C virus. Understanding these risk factors is key to early detection and prevention.

1. People who use or have used injectable drugs

2. Individuals born between 1945 and 1965 (Baby Boomers), a group shown to have higher infection rates

3. Patients undergoing hemodialysis

4. Recipients of blood transfusions or organ transplants before 1992

5. People living with HIV

6. Healthcare workers exposed to contaminated needles

7. Infants born to mothers with hepatitis C

If you belong to any of these categories, it’s advisable to get tested, even in the absence of symptoms.

How Is Hepatitis C Diagnosed?

Diagnosis begins with a blood test to detect the presence of hepatitis C antibodies. If antibodies are found, a second test HCV RNA test is conducted to confirm an active infection by checking for the virus’s genetic material in the blood.

Further evaluations may include :-

1. Liver function tests to assess how well the liver is working

2. Fibroscan or liver biopsy to evaluate the extent of liver damage

3. Genotype testing to determine the virus strain, which helps guide treatment decisions

Early diagnosis can prevent complications and improve treatment outcomes significantly.

Treatment Options for Hepatitis C

The good news is that hepatitis C is now curable in most cases. Antiviral medications, particularly direct-acting antivirals (DAAs), have revolutionized treatment. These drugs target the virus directly, stopping it from multiplying in the body.

Key Points About Hepatitis C Treatment:

1. Treatment duration is usually 8 to 12 weeks

2. Cure rates exceed 95% for most genotypes

3. Fewer side effects compared to older therapies

4. DAAs are taken orally (as tablets), making them convenient and non-invasive

However, access to medication and affordability may vary by country or region. It’s essential to consult a hepatologist or infectious disease specialist for a tailored treatment plan.

Can Hepatitis C Be Prevented?

Currently, there is no vaccine for hepatitis C, but you can reduce your risk by following these precautions :-

1. Avoid sharing needles, syringes, or any injection equipment

2. Ensure tattoos and piercings are done with sterilized tools

3. Practice safe sex, especially with new or multiple partners

4. Use gloves when handling blood or wounds

5. Regularly test for hepatitis C if you belong to a high-risk group

For healthcare professionals, adhering to standard safety protocols and using protective gear is critical in preventing occupational exposure.

Living with Hepatitis C

Being diagnosed with hepatitis C can feel overwhelming, but with today’s medical advancements, most people can live long, healthy lives. The key lies in early diagnosis, adherence to treatment, and regular monitoring.

Lifestyle adjustments can also help protect liver health :-

1. Avoid alcohol and recreational drugs

2. Eat a liver-friendly diet low in saturated fats

3. Maintain a healthy weight

4. Stay up to date with vaccines for hepatitis A and B, as co-infection can worsen liver damage

Conclusion

Hepatitis C is a manageable and often curable disease when caught early and treated appropriately. Due to its silent nature, many people may carry the virus without knowing it. That’s why awareness, regular testing, and timely treatment are essential especially for those in high risk groups.

With newer medications offering high cure rates and fewer side effects, the outlook for people diagnosed with hepatitis C has improved drastically. If you suspect you might be at risk, don’t delay getting tested. Early intervention can make all the difference in preserving your liver health and overall well-being.
