Hepatitis

Hepatitis refers to inflammation of the liver. The liver plays a vital role in digestion, metabolism, detoxification, energy storage, and the production of important proteins. When the liver becomes inflamed, its ability to perform these functions can be affected. Hepatitis may be short-term (acute) or may continue for many years (chronic), depending on its cause.

There are several types and causes of hepatitis, including viral infections, alcohol-related liver injury, fatty liver disease, autoimmune conditions, medications, and certain metabolic disorders. Some forms of hepatitis cause few or no symptoms, while others can lead to significant liver damage if left untreated.

Our hepatitis service focuses on accurate diagnosis, identification of the underlying cause, appropriate treatment, and long-term monitoring to help protect liver health and prevent complications.

What Is Hepatitis?

Hepatitis occurs when liver cells become inflamed. Inflammation may develop suddenly or gradually over time. The impact on the liver depends on the cause, duration, and severity of the inflammation.

Viral hepatitis is one of the most recognized forms and includes hepatitis A, B, C, D, and E. These infections differ in how they are transmitted, how long they usually last, and how they affect the liver.

Hepatitis A and many cases of hepatitis E are generally acute illnesses and do not usually result in chronic liver disease. Hepatitis B, C, and D can become chronic in some individuals and may increase the risk of fibrosis, cirrhosis, and liver cancer.

Hepatitis can also occur without a viral infection. Alcohol-related liver disease, metabolic dysfunction-associated steatotic liver disease (MASLD), autoimmune hepatitis, and certain medications can all cause liver inflammation.

Causes of Hepatitis

Understanding the cause of hepatitis is essential because treatment varies considerably depending on the underlying condition.

Common causes include:

  • Hepatitis A, B, C, D, and E viral infections
  • Alcohol-related liver injury
  • Metabolic dysfunction-associated steatotic liver disease
  • Autoimmune hepatitis
  • Certain prescription medicines
  • Exposure to specific toxins
  • Genetic and metabolic liver disorders

In some situations, more than one factor may contribute to liver inflammation. For example, chronic viral hepatitis combined with alcohol consumption or metabolic risk factors may increase the risk of progressive liver damage.

Symptoms of Hepatitis

Many people with hepatitis have no noticeable symptoms, particularly during the early stages. This means that liver inflammation can sometimes continue unnoticed for a long period.

When symptoms occur, they may include:

  • Tiredness and weakness
  • Loss of appetite
  • Nausea or vomiting
  • Abdominal discomfort, particularly in the upper right side
  • Fever in some acute infections
  • Dark-coloured urine
  • Pale stools
  • Itching
  • Joint or muscle aches
  • Yellowing of the skin or eyes (jaundice)

The presence and severity of symptoms do not always reflect the amount of liver damage. Some people with significant chronic hepatitis may feel completely well.

Diagnosis of Hepatitis

Accurate diagnosis begins with a detailed medical history and clinical evaluation. Blood tests are commonly used to assess liver enzymes and liver function and to determine whether a viral infection or another cause of hepatitis is present.

For viral hepatitis, specific blood tests can identify viral antigens, antibodies, or genetic material. These tests help determine whether an infection is current, previous, acute, or chronic.

Imaging such as ultrasound may be recommended to assess the liver and surrounding organs. Non-invasive tests can also help estimate the degree of liver fibrosis or scarring.

In selected cases, additional investigations may be necessary to establish the cause of liver inflammation or determine the extent of liver injury.

Treatment for Hepatitis

Treatment depends on the type and cause of hepatitis.

Some acute forms of hepatitis may resolve naturally with supportive care and monitoring. Other forms require specific medical treatment.

Chronic hepatitis B may require antiviral medication in patients who meet treatment criteria. The aim is to suppress the virus, reduce ongoing liver inflammation, and lower the risk of complications.

Hepatitis C can now be treated effectively in most patients with modern direct-acting antiviral medicines. Treatment is usually well tolerated and can eliminate the virus in the vast majority of appropriately treated individuals.

Autoimmune hepatitis may require medicines that reduce abnormal immune system activity and control inflammation. Treatment for alcohol-related or metabolic liver disease focuses on addressing the underlying causes and preventing continued liver injury.

Your treatment plan should be individualized based on the type of hepatitis, viral or disease activity, liver function, fibrosis stage, other medical conditions, and previous treatment history.

Preventing Liver Damage and Complications

Early diagnosis and appropriate treatment can help prevent hepatitis from progressing to advanced liver disease.

Patients with chronic hepatitis may require regular monitoring of liver function and fibrosis. Depending on the type and severity of disease, surveillance for complications such as cirrhosis and liver cancer may also be recommended.

Vaccination is an important method of prevention for certain forms of viral hepatitis. Safe food and water practices, appropriate infection-control measures, and avoiding exposure to infected blood or body fluids can also reduce the risk of transmission for certain hepatitis viruses.

Patients with liver disease should avoid excessive alcohol consumption and should discuss medications and supplements with their healthcare provider to ensure they are appropriate for their liver condition.

Why Specialist Hepatitis Care Matters

Hepatitis encompasses a wide range of conditions, and the correct diagnosis is essential for choosing effective treatment. A specialist evaluation can determine the underlying cause, assess the degree of liver damage, and establish an appropriate treatment and monitoring plan.

Our approach emphasizes accurate diagnosis, individualized therapy, prevention of complications, and long-term liver health. Whether hepatitis is newly diagnosed or has been present for many years, appropriate medical care can help control the disease and reduce the risk of progressive liver damage.

When Should You Seek Medical Advice?

You should consider medical evaluation if you have persistent abnormal liver blood tests, unexplained jaundice, ongoing fatigue, risk factors for viral hepatitis, or a known history of liver disease.

Urgent medical attention may be necessary if you develop severe jaundice, confusion, vomiting blood, black stools, significant abdominal swelling, severe weakness, or other rapidly worsening symptoms.

Many forms of hepatitis can be successfully managed, and some can be cured. Early evaluation provides an opportunity to identify the cause, start appropriate treatment, and protect the liver from long-term damage.
