Pathophysiology


 Several factors have been implicated in the etiology of cirrhosis: alcohol
consumption (is the major causative factor), nutritional deficiency with reduced
protein intake (excessive alcohol intake is the major causative factor in fatty
liver and its consequences .)

 Other factors may play a role, including exposure to certain chemicals (carbon
tetrachloride, chlorinated naphthalene, arsenic, or phosphorus) or infectious
schistosomiasis.

 Twice as many men as women are affected.

 Most patients are between 40 and 60 years of age.

 The destroyed liver cells are replaced gradually by scar tissue; eventually the
amount of scar tissue exceeds that of the functioning liver tissue.

 Islands of residual normal tissue and regenerating liver tissue may project from
the constricted areas, giving the cirrhotic liver its characteristic hobnail
appearance.

Clinical Manifestations


 Signs and symptoms of cirrhosis increase in severity as the disease progresses.
The severity of the manifestations helps to categorize the disorder into two main
presentations

1. Compensated cirrhosis, with its less severe, often vague symptoms, may be
discovered secondarily at a routine physical examination.
