Studies suggests that triggers in your environment can alter the way your genes express themselves—effectively turning genes on or off. What’s even more interesting is that you may be able to partially pass these changes on. Your life experience, and that of your family, may in some ways change your DNA.

Alcoholism has many causes, with genetic and environmental factors playing a role. One common reason why people become dependent on alcohol is self-medication. Anxiety, depression, and a number of other disorders are linked to excessive alcohol use.

Among those abusing alcohol, people who are genetically predisposed to alcoholism have a higher risk of developing an alcohol use disorder. Although people can inherit alcoholic tendencies, the development of an alcohol use disorder is also dependent on social and environmental factors. Some who have inherited genes making them susceptible to alcoholism are responsible drinkers or never take a drink in their life.

It can also be beneficial to better learn more about possible causes of alcoholism for that individual. Because alcoholism is only partly genetic, a single person with an alcohol use disorder in your family may not be a cause of concern for you or other family members. However, if there is a notable trend of addiction, it is beneficial to understand this. Environmental factors can also dictate how a person uses alcohol and whether there is an elevated risk for the development of an alcohol use disorder. Many of these factors are more present in childhood, such as growing up around alcohol and the normalization of problematic behaviors revolving around alcohol.

Family history is also a significant factor in a person’s risk of developing AUD. Having a close relative with an AUD, such as a parent or sibling, can increase a person’s risk of developing it. This increased risk may be due to genetic and environmental factors, such as growing up in a household where alcohol use or alcohol abuse was common. While genetics can increase a person’s risk of developing AUD, it’s not the only factor. Environmental factors such as exposure to alcohol, social influences, and stress may also lead to alcoholism.


The second step is metabolism of the acetaldehyde to acetate by ALDHs; again, there are many aldehyde dehydrogenases, among which ALDH2 has the largest impact on alcohol consumption20. Because of a wide range of wild symptoms that blend into each other, recognizing a dual diagnosis can be difficult. The symptoms of each can also look vastly different from one person to the next.

The goal is to stop drinking and give your body time to get the alcohol out of your system. Most people go to a hospital or treatment center because of the withdrawal symptoms. Genes that affect alcohol consumption may increase the overall risk by increasing drinking, or reduce risk by reducing drinking. However, for mash certified sober homes those who have the genes that reduce drinking and drink heavily despite them, the risk increases. For example, if one of your parents struggles with substance abuse problems, you’re more likely to do so, too. However, unlike with other hereditary conditions, the predisposition does not translate into inevitability.

Research has shown that genetics may be involved in developing alcoholism. Studies have found that children of parents who struggle with alcoholism are more likely to develop alcohol use disorders. Researchers have also identified specific genes and gene variants that may contribute to an increased risk of developing alcoholism. Additionally, epigenetics, which is the study of how genes are expressed and regulated, also contributes to the development of AUD. Epigenetic changes can be caused by environmental factors and can affect gene expression. For example, stressful or traumatic experiences can cause epigenetic changes that increase the risk of developing AUD.

  • In other words, excessive drinking as an adult could impact your DNA, and even alter the genes you pass down to your children.
  • Among the behavioral traits parents can pass on to their children is a predisposition toward alcohol abuse and addiction.
  • Total abstinence from alcohol may be advisable for family members of subjects with the highly heritable form of alcoholism.
  • Over the next few years, we anticipate the identification of additional common and rare variants contributing to the risk of alcohol dependence.
  • Maintaining moderate drinking habits may be harder for them than for people without a family history of drinking problems.

Ria Health is one online program that gives you access to medications, medical support, coaching, and digital tools, all from an app on your smartphone. The University of Cambridge published a review of 12 studies involving twins and adopted children. This review supports what most people knew all along—alcoholism, to some extent, runs in the family. Based on these findings, heredity is one of the risk factors that predispose a person to AUD.

Is Alcoholism Inherited?

While genetics might also influence these issues, you don’t need a family history of alcoholism to struggle with one of these problems. The research on epigenetics and alcohol is still developing, but some studies suggest there is a link. Alcohol may be one of the substances that can alter the expression of your genes. In other words, excessive drinking as an adult could impact your DNA, and even alter the genes you pass down to your children. This might increase the likelihood that they will also develop alcohol use disorder. Second, research shows that the risk for alcoholism is higher among people who begin to drink at an early age, perhaps as a result of both environmental and genetic factors.

As it relates to alcoholism, genes, environment and social interaction can all affect a person’s risk level for alcohol addiction. Still, there isn’t one specificalcoholic genethat makes a person addicted to alcohol. Instead, environmental and social factors play a large role in the outcome.

In fact,some studiesfound that approximately 45% to 65% of risks related to alcoholism may be caused by genetic factors. These studies show that children with a family history of alcohol addiction are twice as likely as the general population to suffer from alcohol-related issues. In addition to affecting alcohol addiction risks, these genetic factors may lead to increased alcohol consumption and heighten the risk of alcohol-related diseases, including certain cancers. In fact,new data suggeststhat there may be even more genetic variants involved in alcohol dependence. For example, it can be challenging to separate the effects of genetics from environmental factors, such as upbringing or social influences.

Genetics and Alcohol-Associated Diseases

Is alcoholism genetic is a question many families ask after seeing one or more family members spiral in addiction. Millions of Americans have close relatives suffering with alcoholism, so it is not a new question. The bottom line is that people want to know if it is safe for them to drink, if a family member cannot. Or they want to protect children to help them grow into healthy adults without bearing the vulnerability of a legacy of alcoholism.

However, it does mean you should take extra precautions as you could have a strong susceptibility toward alcoholism. There are several other genes that have been shown to contribute to the risk of alcohol dependence as well as key endophenotypes. The earliest genes were typically identified as a result of family-based analyses.
