Is Alcoholism Hereditary? Alcoholism and Genetics Learn More

Although learning about the genetic risk factors of AUD can be quite disheartening for those whose parents are alcoholics, there is reason to take heart! There are so many proactive, protective steps which can help people at risk of AUD strengthen and protect themselves from developing this disorder. A review of studies from 2020, which looked at a genome-wide analysis of more than 435,000 people, found 29 different genetic variants that increased the risk of problematic drinking. Open communication about family experiences and early education about alcohol risks can reduce the chance of dependency. It’s not uncommon for the real reason you’re drinking to be mental health issues, untreated trauma, or life stress.

Environmental Risk Factors:

Alcohol addiction, a chronic relapsing disorder characterized by compulsive alcohol-seeking behavior and loss of control over consumption, is a major global health problem. It is estimated that around 15 million people in the United States alone struggle with alcohol use disorder (AUD). While environmental factors play a significant role in the development of alcohol addiction, researchers have also identified a strong genetic predisposition to this disorder. Similarly, individuals with genetic variations in the brain’s reward system may benefit from targeted therapies that modulate dopamine release, helping to reduce cravings and prevent relapse.

  • Genetic testing and personalized medicine approaches may be utilized to identify individuals at higher risk for alcohol addiction and mental health disorders.
  • Understanding the genetic components of AUD opens new avenues for personalized treatment approaches.
  • Alternatively, genetic variations that increase the risk of one disorder may also indirectly contribute to the development of another disorder.

Is Alcoholism Hereditary? The Role of Genetics in Addiction

Their studies have shown that genes like ADH1B and ALDH2 are crucial in alcohol metabolism, with specific variants more prevalent in the Asian population. This has led to groundbreaking insights into why some individuals might experience adverse reactions to alcohol, offering a protective factor against excessive consumption. A proper diagnosis is essential for developing an effective treatment plan, especially for those with genetic risk factors who may need specialized approaches.

The Role of Genetics in Alcohol Addiction

This complexity makes it difficult to pinpoint specific genes that directly develop AUD. AUD isn’t directly caused by genetics, but genetics may predispose you to developing AUD later in life. This risk is considered hereditary and may be passed down to you if you have a family history of AUD. Your genetic risk refers to the likelihood that specific genes or genetic variants passed down to you will lead to a particular condition. Chronic heavy alcohol use can also cause long-term problems affecting many organs and systems of the body. Long-term overuse of alcohol also increases the risk of certain cancers, including cancers of the mouth, throat, esophagus, liver, and breast.

Risk Factors: Varied Vulnerability to Alcohol-Related Harm

But in the decades since Angier’s article, scientists have made strides in figuring out the mystery of what really underlies this unique disease. Mixing alcohol with other drugs can also compound the risk of developing alcoholism symptoms alcohol dependence. Drinking in moderation and limiting your alcohol consumption can help to decrease the odds of developing alcohol dependence and also for alcoholism. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) publishes that about 16 million Americans struggle with an alcohol use disorder (AUD).

A 2018 study also showed that genetic factors account for 40 to 60 percent of the reasons people develop AUD.14 Since that study, specific genes have been identified that link with the development of the disorder. Genetics are responsible for about half of the risk of developing AUD.12 Although AUD is related to genetics, this doesn’t mean there’s a specific gene you inherit that develops the disorder. On the other hand, not having genes linked to alcoholism doesn’t mean you won’t develop an addiction. AUD is complex and intertwines biological, environmental, and behavioral factors.

Children of people with alcohol use disorder are two to six times more likely than the general public to develop alcohol problems. This increased risk is likely due in part to shared genetic factors, but it may also be related to environment, lifestyle, and other nongenetic influences that are shared by members of a family. Understanding the role of genetic variants is alcoholism a genetic disease in alcohol withdrawal severity is important for developing personalized treatment approaches. By identifying individuals who are genetically predisposed to experiencing more severe withdrawal symptoms, healthcare professionals can tailor their interventions to better address their specific needs. While genetics play a crucial role in alcoholism, it is important to note that environmental factors also contribute to its development.
