What condition is characterized by inflammation of the liver?

Hepatitis is the condition characterized by inflammation of the liver. It can be caused by various factors, including viral infections, alcohol use, and autoimmune diseases. The inflammation can lead to a range of symptoms such as fatigue, jaundice, abdominal pain, and elevated liver enzymes in the blood.

Cirrhosis refers to the scarring of liver tissue that occurs as a result of chronic liver inflammation and damage, but it is not the initial inflammatory condition itself. Hepatomegaly is simply an enlargement of the liver and signifies an underlying problem but does not specifically denote inflammation. Cholecystitis involves inflammation of the gallbladder, not the liver. Therefore, hepatitis is the most accurate term among the options given for liver inflammation.
