Which of the following statements regarding the causes of hepatitis is correct?

• A. Infectious agents, toxins, or drugs
• B. Autoimmune processes only
• C. Bacterial infections only
• D. Genetic mutations only

Answer: (A)

Hepatitis results from several different insults to the liver, so recognizing the broad categories that can cause it is key. Infections from viruses (like the hepatitis viruses), exposure to toxins (including alcohol and other environmental hepatotoxins), and injury from drugs all can lead to liver inflammation. That wide-ranging view is why the statement about infectious agents, toxins, or drugs being causes is correct—it encompasses the main ways hepatitis occurs. Autoimmune processes can cause hepatitis, but they are not the only cause, so saying “autoimmune processes only” is too narrow. Bacterial infections are not a typical sole cause of hepatitis, and genetic mutations alone do not explain the majority of hepatitis cases, though some genetic or metabolic liver diseases can resemble hepatitis.
