Why Binge Drinking Even Once a Week is Bad

Drinking an entire week's worth of alcohol in one night is not the cheat code you think it is.
When you binge drink, your brain activity slows down and essential bodily functions are affected. Your judgment becomes impaired, you get drowsy and you become susceptible to blackouts. Binge drinking even once a week can have a cumulative effect on your health, too, increasing your risk of long-term health issues such as cancer, liver disease, hypertension and memory problems.
An American Journal of Preventive Medicine study found that moderate drinkers who binge drank were nearly five times more likely to experience multiple alcohol-related problems than moderate drinkers who spread their alcohol consumption more evenly throughout the week.
Simply put, the total amount of alcohol you consume doesn't tell the whole story. Drinking patterns matter.

What is binge drinking?

One in four American adults who binge drink consume at least eight drinks during a binge occasion, according to the Centers for Disease Control and Prevention (CDC). That total doubles the general definition of binge drinking, which is four or five drinks in one sitting. Binge drinking is most common among younger male adults aged 18 to 34.
Michiganders may be uniquely susceptible to binge drinking, compared to other regions of the country. The CDC states that binge drinking is common among adults who have household incomes of $75,000 or more, are non-Hispanic white or live in the Midwest.

Short-term effects of binge drinking

You may feel a bit of a rush from that first glass of beer or wine. Maybe your mood is lightened and you become more talkative in a social setting.
But after a couple more drinks, your brain activity slows down and essential bodily functions are affected. Here are some possible severe effects of a night spent binge drinking:
  • Blackouts (alcohol-induced amnesia) and memory loss
  • Decreased bladder control
  • Drowsiness
  • Impaired balance and coordination
  • Impaired judgment
  • Lowered inhibitions
  • Memory loss
  • Mood swings
  • Nausea or vomiting

Effects of binge drinking on health

If you make a habit out of binge drinking, you could expose yourself to a myriad of long-term health problems. Our liver breaks down most of the alcohol we consume, damaging liver cells in the process. Alcohol also scars the liver of about 1 in 5 heavy drinkers. But excessive drinking can harm far more than just your liver. Alcohol is a causal factor in more than 200 disease and injury conditions according to the World Health Organization. Some of those conditions include:
  • Cancer of the breast (among females), colon, esophagus, mouth, larynx, liver, pharynx and rectum.
  • Fetal alcohol spectrum disorders (FASDs) 
  • Hypertension (high blood pressure)
  • Liver damage and/or liver disease
  • Memory or learning problems
  • Motor vehicle crashes
Other external and ancillary effects of excessive drinking can include the risk for sexually transmitted diseases, unintended pregnancy and physical harm to oneself or others, including falls, domestic violence, homicide, suicide or sexual assault.
Another danger of habitual binge drinking is the chance it develops into alcohol use disorder (AUD). AUD is a medical condition characterized by one’s inability to stop or control alcohol use, despite negative consequences.
AUD encompasses alcohol abuse, alcohol dependence, alcohol addiction and alcoholism. Binge drinking regularly can increase the risk of AUD.
Symptoms for AUD are behavioral. They include:
  • Continued drinking despite alcohol causing issues with family or friends
  • Continued drinking despite it making your feel depressed or anxious
  • Inability to control the amount of drinking
  • Increased alcohol tolerance
  • Unsuccessful attempts to stop drinking

Alcohol abuse treatment

Anyone seeking help for alcohol dependency should start with their primary care provider or a mental health provider.
