Alcohol and Liver Health Risk
Alcohol is metabolized by the liver, and excessive drinking causes progressive liver damage. The stages range from alcoholic fatty liver to alcoholic hepatitis and, ultimately, cirrhosis. One US standard drink contains 14 grams of pure alcohol — the same amount found in a 12 oz regular beer, a 5 oz glass of wine, or a 1.5 oz shot of spirits.
The NIAAA defines heavy drinking as more than 14 drinks per week for men and more than 7 per week for women. Exceeding these thresholds substantially raises the risk of fatty liver, hepatitis, and cirrhosis. Taking at least two alcohol-free days per week helps the liver recover between sessions.
Frequently Asked Questions
Binge drinking (5+ drinks in one sitting for men, 4+ for women) spikes blood alcohol to levels that cause acute liver cell damage and increases cardiovascular risk. Even if your weekly total is similar to a daily moderate drinker, large single-session doses are more harmful.
Early warning signs include fatigue, upper-right abdominal discomfort, and loss of appetite. More advanced damage can cause jaundice (yellow skin or eyes), swollen abdomen, and easy bruising. If you notice these symptoms, consult a healthcare provider promptly.
