Hepatitis: Types, Causes, Symptoms, Diagnosis & Treatment

Hepatitis refers to inflammation of the liver, an essential organ responsible for metabolism, detoxification, digestion, and immunity. Hepatitis may be acute (short-term) or chronic (long-lasting) and can occur due to viral infections, alcohol, medications, autoimmune disease, or metabolic disorders.

Early diagnosis and appropriate treatment are crucial to prevent liver damage, cirrhosis, or liver cancer.

 What Is Hepatitis?

The liver performs vital functions such as:

• Detoxifying harmful substances

• Producing bile for digestion

• Storing energy (glycogen)

• Making proteins and clotting factors

In hepatitis, liver cells become inflamed and damaged, reducing the liver’s ability to function normally.

 Types of Hepatitis

🔹 Viral Hepatitis (Most Common)

Type

Transmission

Nature

-Hepatitis A

.Contaminated food/water

.Acute, self-limiting

-Hepatitis B

.Blood, sexual contact, mother-to-child

.Acute or chronic

Hepatitis C

Blood exposure

Usually chronic

Hepatitis D

Requires Hepatitis B infection

Severe

Hepatitis E

Contaminated water

Acute (dangerous in pregnancy)

🔹 Non-Viral Hepatitis

• Alcoholic hepatitis

• Drug-induced hepatitis (painkillers, antibiotics)

• Autoimmune hepatitis

• Fatty liver–related hepatitis (NASH)

 Symptoms of Hepatitis

Symptoms vary depending on type and stage.

Common Symptoms

• Fatigue and weakness

• Loss of appetite

• Nausea and vomiting

• Upper right abdominal pain

• Fever (acute viral hepatitis)

Signs of Liver Dysfunction

• Yellowing of eyes and skin (jaundice)

• Dark urine

• Pale stools

• Itching

• Swelling of legs or abdomen (advanced disease)

 Many people with chronic hepatitis may have no symptoms for years.

 Warning Signs (Seek Urgent Care)

• Severe jaundice

• Confusion or drowsiness

• Bleeding tendency

• Severe abdominal swelling

• Persistent vomiting

• 🧪 Diagnosis

Hepatitis is diagnosed using blood tests and imaging.

Investigations

• Liver Function Tests (LFTs) – ALT, AST, bilirubin

• Viral markers (HBsAg, Anti-HCV, etc.)

• Ultrasound abdomen

• FibroScan – liver fibrosis assessment

• Liver biopsy (selected cases)

 Treatment & Management

Viral Hepatitis

Type

Treatment

Hepatitis A & E

Supportive care

Hepatitis B

Antiviral therapy (if chronic/active)

Hepatitis C

Direct-acting antivirals (curable)

Non-Viral Hepatitis

• Stop alcohol completely

• Discontinue offending drugs

• Immunosuppressive therapy (autoimmune hepatitis)

• Weight loss & metabolic control (NASH)

Self-medication can worsen liver injury.
