Is Alcoholism Genetic? Why Alcohol Use Disorder Runs in Families

Genetic and environmental factors can affect the reward system’s function. As we’ve learned more about how genes play a role in our health, researchers have discovered that different factors can affect the expression of our genes. The child of a person with AUD is more likely to suffer from AUD since alcohol dependence and consumption level are partly inheritable traits, but it doesn’t necessarily mean that they will inevitably develop it later on. If you have a parent or close relative who has alcohol use disorder (AUD), you may wonder if you’re at risk for developing it yourself. There are also countless environmental factors (work, stress, relationships) that may lead to alcoholism. Among the behavioral traits parents can pass on to their children is a predisposition toward alcohol abuse and addiction.

A growing body of scientific evidence seems to confirm alcoholism and a genetic predisposition. This means if you have more than one close relative with an alcohol use disorder, you may have inherited genes that put you at risk. Concerns about alcohol consumption should be addressed by a medical professional. Feeling out of control in regard to drinking and feeling as though one drinks too much are indicators that there is a problem. Medically supervised detox programs and evidence-based rehabilitation programs are available that specialize in treating AUD. In the future, there may be genetic therapies that help people control how much alcohol they consume; for now, behavioral therapies have proven very effective at managing these chronic health conditions.

Genes contributing to the risk of alcohol dependence

About half of your susceptibility to developing a substance use disorder (SUD) can be hereditary. Genetics can mark you as more prone to use alcohol, tobacco products or drugs such as cocaine, heroin and opioids. Too much alcohol affects your speech, muscle coordination and vital centers of your brain. A heavy drinking binge may even cause a life-threatening coma or death. This is of particular concern when you’re taking certain medications that also depress the brain’s function.

Additionally, about 1.7% of adolescents ages 12 to 17 were reported as having alcohol use disorder in 2019. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), 5.6% of adults in the United States were living with alcohol use disorder in 2019. Your socioeconomic status can directly affect your mental and physical well-being. If you live in a situation of poverty, for example, or in an area with limited resources, you may be less likely to have access to quality foods, community services, or adequate healthcare. While intoxication doesn’t necessarily indicate the individual has a problem with alcohol, recurrent intoxication may signify alcohol misuse—or addiction.

Alcohol Addiction And Genetics

AUD doesn’t form because of a single gene, nor are genetics the only reason why someone develops an alcohol use disorder. Alcohol use disorder (AUD) is a condition where it’s difficult to stop drinking alcohol, even when it affects your work, relationships, and health. Researchers at the University of California at San Francisco (UCSF) are using fruit flies to find the genetic causes of alcoholism. According to scientists, drunken drosophila fruit flies behave the same way humans do when they are drunk. In addition, a fruit fly’s resistance to alcohol appears to be controlled by the same molecular mechanism as humans. Environmental factors, as well as gene and environment interactions account for the remainder of the risk.

  • They should also have proactive strategies to avoid dropping out, involve the family in treatment, employ qualified and certified staff, and be accredited by an external regulatory organization.
  • Your socioeconomic status is made up of economic and societal factors such as your income, level of education, employment, location of residence, and available resources.
  • Those who have mental illnesses, especially anxiety, depression, bipolar disorder, and schizophrenia are very likely to struggle with co-occurring alcohol use disorder.
  • They should emphasize linking different phases of care, such as connecting patients to mental health professionals, housing, and peer support groups when transitioning out of the acute phase of care.
  • Many of these ads show drinking as an acceptable, fun and relaxing pastime.

GWAS are
beginning to yield robust findings, although the experience in many diseases is
that very large numbers of subjects will be needed. To date, individual GWAS
studies on alcohol dependence and related phenotypes have been relatively modest
in size, and most do not reach genome-wide significance. This may reflect both
the limited sample sizes and the clinical and genetic heterogeneity of the
disease. As noted above, the functional ADH1B polymorphism is
not represented on GWAS platforms; GABA-receptor genes are often nominally
significant but well below genome-wide significance in these studies. Thus, the
genes and SNPs found through GWAS have had little overlap with previous findings
based on candidate genes/pathways and linkage analyses. Different psychological factors may increase the chances of heavy drinking.

Genes affect alcoholism by making people more likely to develop an addiction to alcohol. A gene is a hereditary unit that is transferred from parents to children. Genes are responsible for the traits of children and how they develop; every person has a set of unique genes. As a technical definition, genes are a sequence of nucleotides that make up parts of a chromosome.

Growing up around family members and close relatives that suffer from alcoholism increases the risk of alcohol abuse for generations to come. When you’re surrounded by people who drink excessively, you can look at alcohol use differently and fall victim to bad habits. There are many risk factors involved in the potential for developing alcoholism. Alcoholism risk Intermittent explosive disorder Symptoms and causes factors do not mean you will develop a drinking problem; however, they should serve as a prevention measure. If you have one or more risk factors, speak with a medical health professional about alcoholism warning signs and prevention resources. Research has shown a close link between alcoholism and biological factors, particularly genetics and physiology.

You might also find it helpful to confide in a trusted loved one whose support can be instrumental in your recovery. You could also look for support groups online or in your area for people with substance use disorders. Alcohol use disorder (AUD) often seems to run in families, and we may hear about scientific studies of an “alcoholism gene.” Genetics certainly influence our likelihood of developing AUD, but the story isn’t so simple.
