Step 1: What does chronic alcohol consumption do to the liver?
Alcohol is processed mainly in the liver. Chronic heavy drinking causes a sequence of liver lesions, and the question asks about the EARLIEST one.
Step 2: The sequence of alcoholic liver disease.
The progression goes in a definite order: Fatty liver (steatosis) first, then Alcoholic hepatitis, then Cirrhosis, and finally Hepatocellular carcinoma as a long-term complication.
Step 3: Why does fatty liver come first?
Even a single episode of heavy drinking can cause fatty liver. When alcohol is metabolized, it increases the ratio of NADH to NAD+. This shift blocks the breakdown of fatty acids and promotes fat accumulation in liver cells (hepatocytes). This happens before any inflammation or cell death.
Step 4: Evaluate the wrong options.
Alcoholic cirrhosis (Option 1) is an end-stage finding requiring years of damage. Alcoholic hepatitis (Option 2) involves inflammation and comes after fatty liver. Hepatocellular carcinoma (Option 4) is the latest and most serious complication.
Step 5: Confirm the correct answer.
Fatty liver (hepatic steatosis) is the earliest, most reversible, and most common liver lesion caused by chronic alcohol use.
Answer: Option (3) — Fatty liver
