1. Steatosis, or fatty liver, is common and usually benign but can progress to steatohepatitis if associated with conditions like obesity, diabetes, or alcohol use. 2. Alcohol is a leading cause of steatohepatitis and the most common type of liver disease in Western nations, due to the toxic byproducts produced when the liver metabolizes alcohol. 3. The pathology of alcohol-related liver disease ranges from reversible fatty liver to fibrosis, cirrhosis, and even liver cancer. Management involves cessation of alcohol and treatment of complications.
