Effects of Alcohol Use

Alcohol’s potential effects on the body are far-reaching. Per a report from the United States Surgeon General, the misuse of alcohol is linked to many physical health concerns ranging from liver disease to cancer to fetal alcohol spectrum disorders. Chronic and heavy drinking is also associated with the risk of alcohol use disorders.1

A recent study found that alcohol is a leading risk factor for both disease and death. It also showed that studies associating low use with protective health effects on the heart and against diabetes in women were outweighed by the overall health risk of alcohol consumption.

In other words, no amount of alcohol consumption is healthy, suggesting that health risk increases with every sip.2

What Are the Short-Term Effects of Alcohol Use?

Alcohol’s effects will intensify and change as a person’s blood alcohol concentration (BAC) rises. BAC measures the percent of alcohol in a person’s bloodstream. As BAC rises, so does the level of intoxication and the more effects alcohol will have.3

A person’s BAC can continue to increase even after they’ve stopped drinking. This means that even if you’ve cut off your alcohol intake for the time being, you can still become further impaired as the alcohol you’ve consumed moves from your stomach and intestine into your bloodstream and circulates through your body.4

Effects of Alcohol at Different Stages of Intoxication

The National Institute on Alcohol Abuse and Alcoholism outlines the typical effects and risks at various levels of alcohol intoxication. These effects can range from mild to life-threatening depending on the BAC Level.4

Symptoms of Alcohol Poisoning

An alcohol overdose (alcohol poisoning) occurs at high levels of alcohol intoxication and is a medical emergency that requires immediate attention, as it can be fatal.5 Symptoms of an alcohol overdose include:4

  • Vomiting.
  • Clammy skin.
  • Profound confusion.
  • Loss of consciousness.
  • Seizures.
  • Slow breathing (less than 8 breaths a minute) or irregular breathing (10 seconds or more between breaths).
  • Slow heart rate.
  • Loss of gag reflex necessary to avoid choking in the case of vomit.
  • Low body temperature, or hypothermia.
  • Bluish or very pale skin color.

Combining alcohol with other drugs that depress the central nervous system, such as opioid prescription painkillers (e.g., oxycodone), heroin, or benzodiazepines (e.g., Xanax), increases the risk of overdose by intensifying each substance’s individual effects.

These drugs compound the effect alcohol has on areas of the brain responsible for life-sustaining functions such as breathing. The combination of these types of drugs with even a moderate amount of alcohol may result in overdose.4

Other Risks of Alcohol Consumption

Excessive alcohol consumption may lead to alcohol dependence or alcohol poisoning, as indicated above, but the potential risks extend beyond overdose.5  The Centers for Disease Control and Prevention (CDC) states that drinking to excess can lead to:5

  • Motor vehicle crashes and other potentially fatal injuries ( falls, drownings, burns, etc.).
  • Physical or sexual assault, suicide, or domestic violence.
  • Sexually transmitted diseases or unintended pregnancy resulting from risky sexual behaviors.
  • Miscarriage, stillbirth, or fetal alcohol spectrum disorders. (NOTE: Any use of alcohol during pregnancy is considered risky and “excessive” by the CDC.)

Long-Term Risks of Alcohol Use

Chronic, heavy alcohol use is associated with a host of long-term physical health problems including:5–8

  • Weakened immune system, increasing the risk of becoming ill.
  • High blood pressure (hypertension).
  • Stroke.
  • Problems with digestion.
  • Nutritional deficiencies.
  • Brain and nerve damage.
  • Reproductive problems in both women and men.

Alcohol’s effects aren’t limited to physical health problems. Chronic, heavy drinking is also associated with mental health disorders, such as anxiety and depression, as well as cognitive problems, such as learning issues and memory loss (including dementia).5,6

How Does Alcohol Affect the Liver?

Because alcohol is metabolized in the liver, the substance’s toxic effects can cause significant and lasting damage to this part of the body. Alcohol-associated liver disease is the number one cause of liver transplants in the U.S., and in 2021, about half of all liver disease deaths involved alcohol.9–11

The process of breaking alcohol down can produce a build-up of fat in the liver. Over time, this can lead to the beginning stages of liver damage, or steatosis (i.e., “fatty liver”). This condition can typically be reversed once the person stops drinking.10

However, the effects of continued heavy alcohol use can progress to alcohol-associated hepatitis and eventually the most severe and permanent stage of liver damage, cirrhosis. The tissue damage and inflammation caused by alcohol can also lead to the development of liver cancer.9,12–14

How Does Alcohol Affect the Heart?

Drinking too much over time or even during a single setting can increase the risk of serious heart problems, including:12

  • High blood pressure.
  • Stroke.
  • Irregular heartbeat.
  • Cardiomyopathy—damage to or abnormality in the left ventricle.

Excessive alcohol consumption may also lead to peripheral arterial disease (PAD) and coronary heart disease (CHD), which can result in a heart attack, cardiac arrest, or heart failure.15

How Does Alcohol Affect the Brain?

Alcohol can have a profound impact on the brain, affecting mood, behavior, and cognitive function. Chronic, excessive alcohol use can increase the risk of certain brain diseases and co-occurring mental health disorders like depression and anxiety.12,16–18

Over time, alcohol-associated changes in the brain can also compel uncontrollable, compulsive use, which could develop into alcohol addiction or an alcohol use disorder. This can be especially concerning for adolescents, whose brains are still developing and even more vulnerable to alcohol’s toxic effects.19,20

In young adulthood, alcohol may negatively influence neurological functioning in several key brain regions and signaling pathways, possibly resulting in:20

  • Lower IQ.
  • Loss of motivation.
  • Higher impulsivity and risk-taking.
  • Reduced attention span.
  • Addiction.

Wernicke-Korsakoff Syndrome

Wernicke-Korsakoff Syndrome (WKS) is a very serious medical condition caused by a lack of adequate thiamine. is commonly linked to poor nutrition, especially a deficiency in Vitamin B1, or thiamine. In fact, up to 80% of alcoholics are thiamine-deficient.6

WKS is a disease that combines two separate conditions, Wernicke’s encephalopathy and Korsakoff’s psychosis.6,21

Wernicke’s encephalopathy is a brief but severe condition that may cause:

  • Vision problems, which may include paralysis of one or both eyes, uncontrolled eye movement, double vision, or vision loss.
  • Mental confusion.
  • Problems with muscle coordination/impaired ability to walk.

Korsakoff’s psychosis is a persistent, debilitating condition that causes significant problems with memory and learning, including:

  • Difficulty establishing new memories.
  • Trouble recalling previous memories in their brain.

For example, an individual with Korsakoff’s psychosis may have a detailed conversation but forget it almost immediately.

In the early stages of WKS, administration of thiamine may help address deficits in brain function. However, approximately 80% of patients are untreated and their condition proceeds to Korsakoff’s psychosis.6,21

For more advanced cases of WKS, especially those where Korsakoff’s psychosis is already present, thiamine may be insufficient to address severe brain damage, and treatment may center around supportive care for the patient.6

Is Drinking Alcohol in Moderation Okay?

No amount of alcohol can be considered completely safe.2 However, if you are going to drink, drinking in moderation can reduce your risk of negative physical health outcomes. Moderate drinking is defined by the Dietary Guidelines as:23

  • Women: Up to 1 alcoholic drink per day.
  • Men: Up to 2 alcoholic drinks per day.
