How does hepatitis affect the liver?

Hepatitis causes inflammation that can damage liver cells, impairing the organ’s core functions such as filtering blood, producing bile, and regulating metabolism. Acute hepatitis may cause fatigue, jaundice, abdominal pain, and abnormal liver blood tests. Chronic inflammation—when infection or injury persists—can lead to fibrosis, cirrhosis, and an increased risk of liver cancer. Medical teams monitor liver enzymes, imaging, and fibrosis scores to determine disease stage and guide treatment decisions. Lifestyle measures such as avoiding alcohol and controlling metabolic risk factors are often recommended alongside medical therapy to protect liver health.

What viruses cause this disease?

Several distinct viruses cause viral hepatitis: hepatitis A, B, C, D, and E. Hepatitis A and E are usually transmitted through contaminated food or water and tend to cause acute, self-limited illness. Hepatitis B and C are bloodborne or sexually transmitted and are more likely to cause chronic infection; chronic hepatitis B or C are major global causes of cirrhosis and liver cancer. Hepatitis D occurs only in people with hepatitis B co-infection and can worsen outcomes. Understanding which virus is present is critical because available treatments differ substantially between them.

How is hepatitis diagnosed medically?

Medical diagnosis begins with a clinical history and blood tests. Basic labs include liver enzymes (ALT, AST), bilirubin, and clotting tests; viral serologies and nucleic acid tests (PCR) identify specific viruses and measure viral load. Imaging such as ultrasound or elastography (FibroScan) evaluates liver structure and fibrosis. In select cases, liver biopsy provides detailed tissue assessment. Accurate staging—distinguishing acute vs chronic infection and degree of fibrosis—directly influences treatment choices. Regular monitoring after diagnosis is essential to track response and detect complications early.

What treatment options exist for hepatitis?

Treatment depends on the viral type and disease severity. For hepatitis A and most hepatitis E cases, care is supportive: hydration, rest, and monitoring until recovery. For chronic hepatitis B, approved nucleos(t)ide antiviral medications suppress viral replication and reduce liver damage; therapy may be long-term and aims to prevent progression rather than always producing a complete cure. Hepatitis C has been revolutionized by direct-acting antiviral (DAA) regimens that target viral proteins; these oral therapies typically cure the infection in the majority of patients after a short course. Hepatitis D therapy requires addressing the underlying hepatitis B infection and may need specialist-directed antiviral strategies. In advanced disease with liver failure or end-stage cirrhosis, liver transplantation becomes a medical option.

How can you find local services and follow-up?

Access to hepatology or infectious disease specialists improves outcomes. Primary care clinicians often coordinate initial testing and vaccination, then refer to local services such as hospital hepatology clinics, community health centers, or infectious disease practices for specialized care. Many regions offer public health programs for hepatitis screening, vaccination (notably for hepatitis B), and linkage to treatment for hepatitis C. Ongoing follow-up typically includes periodic liver function testing, viral load checks when indicated, and surveillance for complications like hepatocellular carcinoma in patients with cirrhosis or advanced fibrosis.

Conclusion

Hepatitis treatment today ranges from simple supportive care for acute, self-limited infections to potent antiviral medications and, for advanced disease, transplant evaluation. Accurate diagnosis and staging of liver involvement determine the best medical strategy. Prevention through vaccination (for hepatitis A and B), harm reduction, and early testing remain central to reducing the burden of viral hepatitis worldwide. Regular medical follow-up and collaboration with local services help ensure appropriate monitoring and timely treatment adjustments.
