What is Viral Hepatitis?
Viral hepatitis is an infection that causes inflammation of the liver, often leading to liver damage, fibrosis, cirrhosis, and in severe cases, liver failure. It is caused by hepatotropic viruses, which include Hepatitis A, B, C, D, and E. Some forms of hepatitis are acute and self-limiting, while others can become chronic and life-threatening if left untreated.
Types of Viral Hepatitis
Hepatitis A (HAV)
-
Caused by ingestion of contaminated food or water.
-
Usually self-limiting and does not lead to chronic liver disease.
-
Symptoms include fever, nausea, jaundice, and fatigue.
-
Preventable through vaccination and proper hygiene.
Hepatitis B (HBV)
-
Spread through blood, unprotected sex, or from mother to child at birth.
-
Can lead to chronic infection, cirrhosis, or liver cancer.
-
Many cases remain asymptomatic until the disease advances.
-
Preventable through vaccination.
Hepatitis C (HCV)
-
Transmitted through blood, often via shared needles, transfusions, or unsterile medical equipment.
-
Can become chronic, leading to liver fibrosis, cirrhosis, or liver cancer.
-
Often asymptomatic in early stages but can cause long-term liver damage.
-
No vaccine available, but effective antiviral treatments can cure the infection.
Hepatitis D (HDV)
-
Occurs only in individuals already infected with Hepatitis B.
-
Leads to more severe liver disease and faster progression to cirrhosis.
-
Preventable by getting vaccinated against Hepatitis B.
Hepatitis E (HEV)
-
Spread through contaminated water and poor sanitation.
-
More severe in pregnant women, sometimes leading to liver failure.
-
Usually self-limiting but can be life-threatening in certain cases.
Symptoms of Viral Hepatitis
Viral hepatitis may be asymptomatic in the early stages, but as the infection progresses, patients may experience:
-
Fatigue and weakness
-
Loss of appetite
-
Nausea and vomiting
-
Jaundice (yellowing of the skin and eyes)
-
Abdominal pain, especially in the upper right side
-
Dark urine and pale stools
-
Fever and joint pain (more common in Hepatitis B)
Diagnosis of Viral Hepatitis
Dr. Nadeem Parvez uses advanced diagnostic techniques to detect and monitor viral hepatitis:
-
Liver Function Tests (LFTs) – To assess liver enzyme levels.
-
Hepatitis Viral Marker Tests – To identify specific hepatitis virus infections.
-
Polymerase Chain Reaction (PCR) Tests – To detect viral load and assess chronic infection.
-
Ultrasound and Fibroscan – To check for liver fibrosis and cirrhosis.
-
Liver Biopsy – In select cases to evaluate liver damage.
Treatment Options for Viral Hepatitis
The treatment approach depends on the type and severity of hepatitis:
-
Hepatitis A and E – Usually self-limiting; treatment focuses on supportive care, hydration, and rest.
-
Hepatitis B – Managed with antiviral medications to reduce viral replication and liver damage.
-
Hepatitis C – Treated with direct-acting antiviral (DAA) therapy, which has a high cure rate.
-
Hepatitis D – Managed by controlling Hepatitis B infection and using antiviral therapy.
-
Lifestyle Changes – Avoiding alcohol, maintaining a healthy diet, and monitoring liver health.
Prevention of Viral Hepatitis
-
Vaccination – Effective vaccines are available for Hepatitis A and B.
-
Safe Food & Water Practices – Avoid contaminated food and water, especially in areas prone to Hepatitis A and E.
-
Safe Medical Practices – Use sterilized medical equipment and avoid sharing needles.
-
Safe Sexual Practices – Practice protected sex to reduce the risk of Hepatitis B and C.
