Impacts of Alcohol

One Standard Drink
Why does alcohol impact women more than men?

Because of several physiological reasons, a woman will feel the effects of alcohol more than a man, even if they both weight the same.

Ability to dilute alcohol

Women have less body water (52% for the average woman v. 61% for the average man). This means that a man's body will automatically dilute the alcohol more than a woman's body, even if the two weigh the same.

Ability to metabolize alcohol

Women have less alcohol dehydrogenase, a liver enzyme that breaks down alcohol, than men. So a woman's body will metabolize alcohol more slowly than a man's.

Hormonal factors

Pre-menstrual hormonal changes cause intoxication to set in faster during the days right before a woman gets her period. Birth control pills or other medication with estrogen will slow down the rate at which alcohol is eliminated from the body.

Women are more susceptible to long-term alcohol-induced damage.

Women who are heavy drinkers are at greater risk of liver disease, damage to the pancreas and high blood pressure than male heavy drinkers. Proportionately more alcoholic women die from cirrhosis than do alcoholic men.

Factors that influence intoxication

Food

Having food in your stomach can have a powerful influence on the absorption of alcohol. The food will dilute the alcohol and slow the emptying of the stomach into the small intestine, where alcohol is very rapidly absorbed. Peak BAC could be as much as twice as high in someone with an empty stomach than in someone who has eaten a meal before drinking. Eating regular meals and having snacks while drinking will keep you from getting too drunk too quickly.

Asian descent

Some people of Asian descent have more difficulty metabolizing alcohol. They may experience facial flushing, nausea, headache, dizziness and rapid heartbeat. It appears that one of the liver enzymes that is needed to process alcohol is not active in these individuals. It is estimated that up to 50% of Asians are susceptible to these reactions to alcohol.

Family History

First-degree relatives (children, siblings or parents) of alcoholics have been estimated to have a seven times greater chance of developing alcoholism. The male relatives of male alcoholics are at particularly high risk, with the expectancy of becoming an alcoholic ranging from 20% to 50%. It appears that this risk factor is not just genetic; growing up with an alcoholic parent contributes to a person's drinking behavior.
