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

Hepatitis is classified into several types based on cause. Hepatitis A and E are usually transmitted through contaminated food or water and are typically acute. Hepatitis B, C, and D are transmitted through blood and body fluids and may become chronic. Non-viral hepatitis includes alcoholic, drug-induced, and autoimmune 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

Hepatitis is most commonly caused by viral infections, including Hepatitis A, B, C, D, and E viruses. Other causes include excessive alcohol consumption, drug-induced liver injury, autoimmune disorders, and metabolic conditions. These factors lead to inflammation and damage to liver cells, affecting normal liver function.

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

• Diagnosis involves blood tests to assess liver function (LFTs) and identify specific viral markers. Imaging studies such as ultrasound may be used to evaluate liver structure. In certain cases, liver biopsy may be required to assess the extent of damage.

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

Treatment depends on the cause and type of hepatitis. Acute viral hepatitis often requires supportive care, including rest and hydration. Chronic hepatitis B and C may require antiviral medications. Avoiding alcohol and hepatotoxic drugs is essential. Regular monitoring is important to prevent progression.

Viral Hepatitis

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.

 Diet & Lifestyle for Liver Health

recommended                                                                                                                                                              Avoid

Balanced, home-cooked food

                                                                                                                                                                                             Alcohol

Fruits & vegetables

                                                                                                                                                                                    Fried foods

Adequate protein

                                                                                                                                                                                  Excess sugar

Whole grains

                                                                                                                                                                Junk & processed food

Adequate hydration

                                                                                                                                                           Herbal/self-medications

Additional advice:

• Maintain healthy body weight

• Exercise regularly

• Avoid sharing needles or razors

 Complications of Chronic Hepatitis

If untreated, hepatitis can lead to serious complications such as chronic liver disease, cirrhosis, liver failure, and liver cancer. Long-term inflammation causes irreversible damage to liver tissue.

• Chronic liver disease

• Cirrhosis

• Portal hypertension

• Liver failure

• Liver cancer (HCC)

Prevention

Preventive measures include vaccination (for Hepatitis A and B), safe food and water practices, avoiding sharing needles, practicing safe sex, limiting alcohol intake, and maintaining good hygiene. Early screening helps reduce transmission and complications.

• Vaccination (Hepatitis A & B)

• Safe drinking water

• Safe sexual practices

• Screened blood transfusions

• Avoid unnecessary injections

• Early treatment of chronic hepatitis

 When to Consult a Doctor

• Persistent fatigue or jaundice

• Abnormal liver test results

• History of alcohol use or drug exposure

• Blood transfusion in the past

• Family history of liver disease
