Laennec's Cirrhosis is primarily caused by which of the following?

Laennec's Cirrhosis, also known as alcoholic cirrhosis, is primarily associated with chronic alcohol abuse. This form of cirrhosis occurs due to the toxic effects of alcohol on liver cells, which leads to inflammation, fat accumulation, and eventually the progression to fibrosis and cirrhosis as liver cells sustain ongoing injury.

The characteristic features of Laennec's Cirrhosis include a nodular appearance of the liver and complications related to advanced liver disease, such as portal hypertension and liver failure. While other factors like obesity, viral hepatitis, and biliary obstruction can lead to liver disease and cirrhosis, they do not characterize Laennec's Cirrhosis specifically, which is fundamentally tied to excessive alcohol intake. Therefore, recognizing the pivotal role of alcohol in this specific type of cirrhosis is essential for understanding its pathology and management in clinical practice.
