The negative effects of alcohol
It should be a surprise to no one that drinking too much alcohol can be bad for you — of course, the definition of "too much" can vary. More on that in a moment.
Here are some of the more common
negative health consequences of excessive alcohol consumption — and good reasons to moderate your intake of alcohol:
- liver disease, including cirrhosis and life-threatening liver failure requiring a liver transplant
- a higher risk of high blood pressure, heart failure, and dementia
- a higher risk of certain cancers, including those of the digestive tract (including colon cancer), breast, and liver
- a higher risk of injury, especially from drunk driving and falls — homicides and suicides are also often alcohol-related
- lapses in judgement — For example, people who are drunk may engage in risky sexual behavior or use other drugs
- a higher risk of depression, anxiety, and addiction which may, in turn, affect one's ability to establish and maintain social relationships and employment
- alcohol poisoning — many people don't realize that if you drink enough alcohol over a short period of time, it can be fatal
- fetal alcohol syndrome — alcohol can damage a baby's developing brain and cause other developmental abnormalities.
Excessive alcohol consumption can cause health problems not only for the drinker, but also for their family, friends, coworkers, and employers.
Are there benefits of alcohol?
While the list of health risks related to excessive alcohol consumption is long, there may also be health
benefits associated with
moderate drinking. There's the psychological or social impact of alcohol. Having a drink while getting together with family or friends can be helpful to relieve stress and promote a sense of well-being. Alcohol has long been considered a "social lubricant" because drinking may encourage social interaction. These benefits are hard to measure.
In addition, studies suggest that moderate drinking (as discussed below) may be linked with a lower risk of:
- heart attack
- the most common type of stroke
- death due to cardiovascular disease
- diabetes
- gallstones.
Despite these potential health benefits, most doctors don't recommend that someone who doesn't drink start drinking, or for a moderate drinker to drink more. That's because these are only correlations (which does not necessarily mean causation). Many of these benefits are quite small, and it's hard to predict who will actually benefit and who may be harmed more than helped by alcohol consumption.
How much alcohol consumption is too much?
The answer has varied over time, but a
widely accepted definition of moderate alcohol consumption — as endorsed by the US Department of Health and Human Services and the US Department of Agriculture — is one drink or less per day for women or two drinks or less per day for men. The lower recommendation for women isn't just because they are, on average, smaller than men. It turns out alcohol affects women differently. They produce less of the enzyme (called alcohol dehydrogenase, or ADH) that breaks down alcohol. In addition, women tend to have more body fat, which tends to retain alcohol.
The definitions for "a drink" in the US are the common serving sizes for beer (12 ounces), wine (5 ounces), or hard liquor (1.5 ounces).
Meanwhile, "high risk" drinking is considered:
- four or more drinks in one day or eight or more drinks per week for women
- five or more drinks in one day or 15 or more drinks per week for men
- Binge drinking is defined as four or more drinks over two hours for women and five or more drinks over two hours for men.
A new study could change what's considered moderate drinking
A
new study analyzed data from nearly 600,000 people who drank at least some alcohol, and monitored their health over time. They found that regardless of gender, higher alcohol consumption was associated with a higher rate of stroke, fatal aneurysms, heart failure, and death. When compared with people who drank less than seven drinks per week:
- Adults drinking seven to 14 drinks per week could expect, on average, a six-month shorter life expectancy as of age 40
- Those drinking 14 to 25 drinks per week could expect a shorter life expectancy by one to two years
- Those drinking more than 25 drinks per week could expect a shorter life expectancy by four to five years
Depending on the country, current guidelines (including those in the US) could allow levels of drinking high enough to shorten life expectancy.
