Hepatitis refers to the inflammation of the liver, which can result from various etiologies, including viral infections, toxin exposure, and autoimmune processes. Biologically, the condition signifies cellular injury within the liver parenchyma, potentially leading to impaired liver function if left untreated. The inflammation is a response to the presence of pathogenic agents or chronic metabolic stress. Diagnosis and management typically involve assessing liver enzymes and identifying the causative agent to determine the appropriate course of treatment, which ranges from supportive care to specific antiviral therapies depending on the underlying cause and the severity of the inflammation.
