The liver performs many essential functions, and when it becomes inflamed due to hepatitis, there is cause for concern. There are many types of viral hepatitis, including A, B and C.


Hepatitis can be caused by:

  • Immune cells in the body attacking the liver and causing autoimmune hepatitis
  • Infections from viruses (such as hepatitis A, B, or C), bacteria, or parasites
  • Liver damage from alcohol, poisonous mushrooms, or other poisons.
  • Medications, such as an overdose of acetaminophen

Diagnostic Tests

A physical examination may show:

  • Enlarged and tender liver

  • Yellowing of the skin

Your doctor may order laboratory tests to diagnose and monitor the hepatitis, including:

  • Abdominal ultrasound

Common Types of Hepatitis

There are 5 main types of hepatitis: A. B, C, D, and E. The most common types are hepatitis A, B, and C. 

What is Hepatitis A?
Hepatitis A is a liver infection caused by the hepatitis A virus. It is highly contagious and spreads through contaminated water or food, or direct contact with an infected person. Hepatitis A can be prevented through vaccinations. 

What is Hepatitis B?
Also a serious liver infection, this form of hepatitis results from the hepatitis B virus. It is most often spread by exposure to the body fluids of an infected person, and can be easily prevented by a vaccine.

What is Hepatitis C?
Hepatitis C is a viral infection that attacks the liver and causes inflammation. Spread by contact with contaminated blood, this type of hepatitis may occur when people share needles or get tattoos with unsterile equipment. There is no vaccine to prevent hepatitis C.

Frequently Asked Questions

What is hepatitis?
Hepatitis is a condition that involves the inflammation of the liver. Because the liver is needed to process nutrients, filter the blood, and fight off infections, its proper function is vital.

Here in the U.S., hepatitis A, B, and C are most common.
