What causes hepatitis and how does it affect the liver?

Viral hepatitis (A, B, C, D, E) is a leading cause of liver inflammation worldwide. Hepatitis A and E usually cause short-term illness transmitted by contaminated food or water; hepatitis B and C can become chronic and lead to fibrosis, cirrhosis, or liver cancer if untreated. Nonviral causes include autoimmune hepatitis, alcohol-related liver disease, and drug-induced liver injury. Clinically, liver inflammation can reduce metabolic and detoxifying functions of the liver, reflected in abnormal liver enzymes and symptoms such as jaundice, fatigue, and abdominal discomfort.

What medical tests diagnose hepatitis?

Diagnosis begins with blood tests: liver function tests (ALT, AST, bilirubin), viral serologies for hepatitis A, B, and C (antibodies and antigens), and PCR-based viral load testing when needed. Imaging such as ultrasound evaluates liver structure and looks for cirrhosis or masses. In some cases, a liver biopsy or noninvasive fibrosis testing (FibroScan, serum fibrosis panels) helps stage disease and guide treatment. Accurate diagnosis is essential to choose the right medical treatment strategy and monitoring plan.

What treatment options are available for hepatitis?

Treatment varies by cause. For acute viral hepatitis A and E, care is mainly supportive: hydration, rest, and monitoring of liver function until recovery. Chronic hepatitis B may require long-term antiviral suppression to reduce liver damage and cancer risk, while chronic hepatitis C is usually treated with curative direct-acting antivirals (DAAs). Autoimmune hepatitis is treated with immunosuppressive therapy. In advanced disease, management focuses on complications of cirrhosis and transplant referral when appropriate. Lifestyle measures—abstaining from alcohol, maintaining a healthy weight, and vaccination where applicable—support medical treatment.

What medications treat hepatitis and what should patients expect?

Antiviral medications for hepatitis B (commonly tenofovir or entecavir in clinical practice) suppress viral replication and decrease progression to cirrhosis. For hepatitis C, DAAs (combinations targeting viral enzymes) achieve sustained virologic response, which is considered a cure in most patients. Autoimmune hepatitis treatment typically includes corticosteroids and steroid-sparing agents like azathioprine. Medication side effects vary; regular monitoring of blood counts, kidney function, and liver enzymes is standard. Treatment duration and regimen are individualized; adherence and follow-up testing are critical for successful outcomes.

How to access local services and ongoing medical care

Start with a primary care clinician who can arrange testing and referrals. Hepatology or infectious disease specialists manage complex or chronic viral hepatitis and treatment with antivirals or immunosuppression. Many public health clinics and community health centers offer screening and vaccination for hepatitis A and B, and some offer direct-acting antiviral programs for hepatitis C. If you have signs of advanced liver disease, seek a specialist center that provides cirrhosis management and transplant evaluation. Always confirm local services and specialist availability in your area.

Conclusion

Effective hepatitis care combines accurate diagnosis, appropriate medication when indicated, regular monitoring, and supportive lifestyle measures to protect liver health. Vaccination prevents hepatitis A and B, while modern antiviral therapies can suppress hepatitis B and often cure hepatitis C.
