cirrhosis

(sərō`səs), degeneration of tissue in an organ resulting in fibrosis, with nodule and scar formation. The term is most often used in relation to the liver, because that organ is most often involved in cirrhosis. Cirrhosis of the liver interferes with the liver's metabolism of nutrients, detoxification of the blood, bile production, and other normal functions (see liverliver,
largest glandular organ of the body, weighing about 3 lb (1.36 kg). It is reddish brown in color and is divided into four lobes of unequal size and shape. The liver lies on the right side of the abdominal cavity beneath the diaphragm.

); its damage is irreversible.

The most prevalent form of cirrhosis of the liver, portal cirrhosis, appears most often in middle-aged males with a history of chronic alcoholismalcoholism,
disease characterized by impaired control over the consumption of alcoholic beverages. Alcoholism is a serious problem worldwide; in the United States the wide availability of alcoholic beverages makes alcohol the most accessible drug, and alcoholism is the most

, and obstruction of the venous circulation with distention of the veins. It is not uncommon for greatly distended veins in the esophagus to rupture and cause massive hemorrhage. Treatment is first aimed at any reversible underlying disease. Supportive measures include avoidance of alcohol, a diet with adequate protein, vitamin supplements, transfusions to replace any blood loss, and removal of accumulated fluid.

Cirrhosis

 

cicatricial shrinkage and deformity of an organ caused by infectious diseases, poisonings, metabolic disturbances, and other factors. Cirrhosis mostly affects parenchymatous organs, for example, the liver (which acquires a yellowish color as a result), the kidneys (nephrocirrhosis), and lungs (interstitial pneumonia). The morphological manifestations of cirrhosis include degeneration and necrosis of parenchymatous elements, distorted regeneration, diffuse proliferation of connective tissues (sclerosis), and structural reorganization and deformity of the organ. Chronic functional insufficiency of the affected organ is one of the main clinical symptoms. Since the proliferation of connective tissues may be due to a variety of factors, a distinction is made between postnecrotic, inflammatory, angiogenic, and metabolic forms of cirrhosis. The disease is believed to be reversible in its early stages.
