Give the pathophysiology of a fatty liver 2º to alcoholism
A combination of increased influx of fatty acids from adipose stores, enhanced hepatic synthesis of triglycerides from fatty acids derived from the diet, decreased fatty acid oxidation, and impaired hepatic lipoprotein synthesis are all of apparent importance in pathogenesis.
Fat begins to be stored in the liver. Hepatomegaly occurs with abdominal tenderness. A postnecrotic pattern may begin to develop, leading to cirrhosis. However, since only 1 out of 12 alcoholics develop cirrhosis, it has been suggested that unknown constitutional or genetic factors also play an important role.1
