Flexible treatment option allowing clients to continue going to work or school. Alcohol is addictive because it changes the way our brains work. Alcohol addiction can lead to several devastating consequences.

The brain craves more alcohol with each drink due to its interaction with the substance. If you or someone you know is struggling with alcohol addiction, don’t be ashamed to reach out for help. Our mission is to shed light on the intricate nature of alcohol addiction, both from scientific and psychological perspectives, and offer effective solutions. Recovery from alcohol addiction is a challenging journey, but it’s not one that individuals have to navigate alone.

Alcohol Addiction Treatment Options

One example is college campuses with a prevalent drinking culture and peer pressure to engage in heavy drinking. Genetics play a significant role in making people more likely to become addicted to alcohol. This results in the brain relying on alcohol to operate normally.

How Does the Body Become Dependent on Alcohol?

An intervention from loved ones can help some people recognize and accept that they need professional help. However, even a mild disorder can escalate and lead to serious problems, so early treatment is important. These changes can compromise brain function and drive the transition from controlled, occasional use to chronic misuse, which can be difficult to control.

This article explores how drinking alcohol can become problematic, focusing on understanding how physical and psychological addiction to alcohol develops. Many factors may contribute to the timeline and presentation of alcohol addiction. How long it takes to develop an alcohol addiction differs for every person. It’s not only about the chemical effects of alcohol but also the emotional and mental factors that can contribute to addiction. Excessive alcohol consumption can occur in certain social settings, making individuals more susceptible to developing alcohol addiction. Social situations, certain cultural values and environments that promote alcohol use may impact the risk of alcohol addiction.

  • A heavy drinking binge may even cause a life-threatening coma or death.
  • It not only takes a toll on the individual battling the addiction but also impacts their friends, family members, and referring professionals.
  • Excess alcohol use changes the brain’s ability to experience pleasure, exercise judgment, and control impulses.
  • The term “alcoholic brain” describes a group of syndromes that arise from both acute and chronic alcohol use.
  • The brain undergoes chemical changes when exposed to alcohol, which is why it has this effect.

How Does Alcoholism Affect the Brain?

You may also have positive experiences or experience positive outcomes in your social life while using alcohol that feel linked to alcohol use. Because alcohol is an integral part of many social gatherings and alcohol use creates the anxiety-reducing effects discussed in the previous section, some individuals may be encourage to use alcohol repeatedly or misuse it progressively as part of social rituals.2 This behavioral pattern is particularly common among the adolescent and young adult groups, where drinking is seen as a pivotal part of social engagement.9 Alcohol may first be used when in a group of peers who are also drinking or in an effort to gain social acceptance.

  • Studies show that in utero exposure to alcohol during fetal development potentially contributes to the baby’s overall risk of developing a substance use disorder, including AUD, in adulthood.12
  • The first step in severe addiction recovery.
  • Alcohol is addictive because it changes the way our brains work.
  • People who are physically dependent on alcohol will need the support of a healthcare professional to stop drinking and may need to detox in hospital under medical or nursing supervision.

Detox

Medicines that help with mental illness can take a while to start working and require patience. Mental health problems can be complicated. This helps them break the cycle of depending on alcohol for support when things get tough. But if you rely too much on alcohol, you can become dependent on it. But this can become a problem if they start relying on alcohol too much. Researchers have identified certain genes that strongly affect how the body processes alcohol.

Preoccupation/Anticipation Stage: craving, impulsivity, and executive function

While tolerance is not the same as addiction, tolerance is one of the clinical criteria for alcohol use disorder (AUD). Your body, in a sense, becomes used to a certain amount of alcohol and you no longer experience the same intensity of euphoria, sedation, or other desired effects with that amount.11 Studies show that in utero exposure to alcohol during fetal development potentially contributes to the baby’s overall risk of developing a substance use disorder, including AUD, in adulthood.12 While the primary concerns of alcohol use during pregnancy related to pregnancy outcomes (e.g., miscarriage, low birth weight) and congenital conditions (e.g., fetal alcohol syndrome), exposure to alcohol in utero may influence future alcohol use and risk of addiction. The risk of alcoholism may increase if an individual is exposed to alcohol at an earlier age.

How is Alcohol Addictive & How Does it Affect the Brain?

The term “alcoholic brain” describes a group of syndromes that arise from both acute and chronic alcohol use. It’s just as addictive as drug substances, and its use causes various physical, psychological, social, and financial problems. “The heritability of alcohol use disorder…nd adoption studies.” Psychological Medicine, Cambridge University Press, August 29, 2014. We believe everyone can recover from addiction, and we take a holistic approach to treatment, addressing all areas of life impacted by addiction. The more “yes” answers a person gives, the more severe their symptoms.

Alcohol (ethyl alcohol) is a simple chemical that can cause significant changes in the complex functions of the human brain and body. This means the brain of an individual with AUD processes the chemical activation of alcohol differently than others. There may be a neurobiological component to the risk of developing addiction. Studies indicate that there may be a genetic component that increases the likelihood that an individual who misuses alcohol—or any other substance—will develop a substance use disorder.16 In cases of severe withdrawal, you could potentially experience tremors, hallucinations, or seizures. Tolerance leads many people to increase the amount of alcohol they consume to achieve the desired effect, such as euphoria, increased sociability, or decreased anxiety.11

What does alcohol do to us when we drink it?

Scientists report differences in how the reward circuit pathways in the brain of those with alcohol use disorder (AUD) differ from those without addiction or before addiction. There is not, as popular cultural sometimes claims, an “alcoholism gene” that would be detectable if you had your personal genome sequenced. While some people can safely detox in an outpatient setting, seek medically supervised withdrawal management services if you experience any medically significant symptoms, such as seizure.12 When you are physically dependent on alcohol, you will experience withdrawal symptoms when you do not use alcohol or you dramatically decrease how much you use it.

Risk factors

As well as ‘psychological addiction’, alcohol can also produce physical dependency. This is sometimes called a ‘psychological addiction’. Over time, that substance or behaviour can start to take priority over other things and we can start to feel uneasy when we are not feeding our habit. But why do some of us carry on drinking when it’s quite clear that it’s doing us more harm than good?

The Diagnostic and Statistical does alcohol dehydrate you symptoms and prevention tips Manual of Mental Disorders (DSM-5), which clinicians use to evaluate and diagnose mental health conditions, defines AUD as “a problematic pattern of alcohol use leading to clinically significant impairment or distress.”1 While alcohol is legal for individuals over the age of 21, it is a mind-altering substance that has a high risk of misuse and addiction. Many people with alcohol use disorder hesitate to get treatment because they don’t recognize that they have a problem. If your pattern of drinking results in repeated significant distress and problems functioning in your daily life, you likely have alcohol use disorder. Binge drinking causes significant health and safety risks.

Impact on your safety

This disorder also involves having to drink more to get the same effect or having withdrawal symptoms when you rapidly decrease or stop drinking. However, most people with AUD—no matter their age or the severity of their alcohol problems—can benefit from treatment with behavioral health therapies, medications, or both. The changes can endure long after a person stops consuming alcohol, and can contribute to relapse in drinking.

Often, individuals in the throes of addiction are in denial or unaware of the extent of their issue. Over time, these changes can impair cognitive function, decision-making, and impulse control. Understanding one’s family history can be crucial in recognizing and addressing this risk. Alcohol can provide a temporary reprieve, but over time, it can exacerbate these issues and lead to a vicious cycle of self-medication. Alcohol affects the central nervous system by depressing its activity, which leads to a range of effects, including relaxation, euphoria, and decreased inhibitions. Understanding why alcohol is addictive is essential in addressing this widespread problem.
