Alcohol metabolism is linked to hereditary prospects as some people get allergic reactions and health repercussions after consuming alcohol. The research focuses on total genetical information about the individual to find whether there is a connection between excessive drinking and alcoholism. There is a massive number of genes that get afflicted by alcoholism, and to get findings from all of them isn’t currently possible. Everything about a person, from eye color to behavior, can be explained by their genes. For example, some persons are genetically prone to drinking because of differences in genes and variations.

This might increase the likelihood that they will also develop alcohol use disorder. If anyone is exposed to large amounts of an addictive substance over an extended period, it is likely that their brain will rewire to crave the substance. Even without a genetic component present, a person can still inherit a predisposition to alcohol use disorder due to the culture they grow up in.

Can a Person Be Born With Alcohol Use Disorder?

“Conversely, there are factors that protect against the development of AUD such as good self-control and self-discipline, neighborhood resources, and parental monitoring and support,” says Adinoff. If the affected person can function, doctors often refer to them as a functioning alcoholic. The disease often progresses relatively inconspicuously and slowly, usually over several years. Sufferers can be unaware of the severity of their illness and may deny it altogether. Worldwide, the ratio of men to women who drink alcohol is 3.8, with 54% of men and 32% of women reporting being drinkers.

The study found that genetic factors accounted for 40-60% of the variance among those who suffer from an AUD. Since that time, certain genes that contribute to AUD have been discovered, and they correlate with the reward center of the brain and how it develops. An experiment using rats at Linköping University in Sweden discovered that those with reduced expression of the gene GAT-3 become addicted to alcohol. This brain chemical that’s widely thought to be involved in alcohol dependence. Furthermore, in collaboration with a co-author from the University of Texas, the researchers took brain samples of deceased people who suffered from alcohol use disorder. There is a distinct link between substance abuse problems and mental health issues such as anxiety, bipolar disorder,  and depression.

Signs of Alcohol Use Disorder

For people to cope with trauma, they may turn to alcohol or drug use, for example. If you’re struggling with excessive drinking or alcoholism, no matter the reason, we can help you heal and rebuild your life. Contact our team today to find out how our program can give you the tools, encouragement, and support you need to live a fulfilling life outside of substance abuse. These environmental and cultural factors are also a culprit in alcohol dependence, as is the prevalence of television shows and movies where drinking to excess is practically as common as breathing. When individuals are exposed to significant amounts of an addictive substance, over time, it is probable that the substance use will “hijack” or rewire the person’s brain to crave it. Even with a genetic predisposition, a person can still inherit a tendency toward AUD as a result of the culture they are emersed in.

  • If you are in doubt, here we can help you answer some questions and find out if you need to start your recovery journey.
  • Several preventative things can be done to reduce the risk of alcohol use and addiction.
  • If anyone is exposed to large amounts of an addictive substance over an extended period, it is likely that their brain will rewire to crave the substance.
  • Science suggests that genetics are roughly half of the underlying reason for AUD.
  • Genetics refers to the DNA sequence, while epigenetics refer to changes in gene expression without altering the DNA sequence.
  • Although the same ADH1B gene was linked to alcoholism risk both in people of European ancestry and African ancestry, the researchers found that different variants in the gene altered risk in the two populations.

In a twin study, researchers found that twins adopted by families with drinking problems were slightly more likely to abuse the substance themselves. However, the chance of alcoholism was much higher if the twins’ biological father suffered from it, whether alcohol was present in the adoptive families or not. The safest and most successful way to overcome an alcohol use disorder is to seek help from a treatment program specializing in detox and alcohol addiction treatment, like Profound Recovery in Woodland Hills, California. Members of our treatment team will work with you to develop a personalized care plan that addresses your recovery needs and goals. If you have an increased risk of an alcohol use disorder, you can get a treatment program as we also offer an outpatient program for part-time hospitalization.

Alcoholism and Environment and Culture

We mentioned that there does seem to be a genetic aspect to higher alcohol tolerance – research shows that genetics are responsible for about half of an individual’s risk for developing alcohol use disorder. Some can be personality-based, and the majority are surprisingly is alcoholism inherited physical traits exhibited while drinking that discourage excess. It makes the inevitability of familial alcoholism seem guaranteed when studies have shown a wide range of outcomes, including some individuals who never develop any symptoms or risks at all.

One of the first tips to avoid alcoholism when it runs in your family is to understand your exact family history. While you may have heard from word of mouth that a distant relative had an alcohol use disorder, that can mean various things. While there is no gene for alcoholism, there are studies that point to genetic contributions. For example, adoption studies have shown that adoptees who’ve struggled with alcohol dependence align more with the trend of their biological parents rather than their adoptive parents. Research conducted by the National Institute of Health has shown, however, that the tendency of repeated alcohol abuse in families isn’t enough to support the genetic argument on its own.

Things like work, stress, relationships, and learned behavior can also affect whether a person develops a drinking problem. Alcohol is widely consumed, but excessive use creates serious physical,
psychological and social problems and contributes to many diseases. Alcoholism
(alcohol dependence, alcohol use disorders) is a maladaptive pattern of
excessive drinking leading to serious problems. Abundant evidence indicates that
alcoholism is a complex genetic disease, with variations in a large number of
genes affecting risk. Some of these genes have been identified, including two
genes of alcohol metabolism, ADH1B and ALDH2,
that have the strongest known affects on risk for alcoholism.

  • As a consequence of long-term alcoholism, psychotic substance use disorders also occur, which were not present before.
  • Some people are more sensitive to stress, making it harder to cope with an unhealthy relationship or a fast-paced job.
  • Sufferers can be unaware of the severity of their illness and may deny it altogether.
  • Genetics and environment are significant factors contributing to alcohol use disorder.
  • Addiction is a chronic disease of the brain, affecting the reward and motivation centers, and it is also a genetic problem.
