Alcohol & Your Liver
Your liver processes almost all of the alcohol you drink — which is exactly why heavy or prolonged use affects it more than almost any other organ. Here's how the risk actually builds, and where the commonly cited safety thresholds come from.
How Alcohol-Related Liver Damage Progresses
Fatty liver (steatosis). Fat starts accumulating in liver cells. This stage is usually reversible with abstinence and typically causes no symptoms.
Alcoholic hepatitis. Continued drinking triggers inflammation of liver tissue. Outcomes vary — from recovery with abstinence to progression toward liver failure in severe cases.
Cirrhosis. Long-term inflammation leads to permanent scarring. At this stage damage is irreversible and can lead to portal hypertension and liver failure.
Men
More than 14 drinks per week, or 4+ in a single sitting, is classed as at-risk drinking under U.S. clinical guidelines (NIAAA).
Women & Adults 65+
More than 7 drinks per week, or 3+ in a single sitting, is classed as at-risk drinking under the same guidelines.
Alcohol + Metabolic Risk
Alcohol use combined with obesity, type 2 diabetes, or existing MASLD compounds liver risk more than either factor alone.
The Early Stage Is Reversible
Fatty liver caused by alcohol typically improves within weeks of stopping or significantly cutting back — before scarring sets in.
