Research into alcoholism and its genetic and potential heritability has been ongoing for decades since then. That being said, over the years, much research has been done to understand the potential genetic link to addiction and alcoholism, and why it seems to run in some families and not others. The journal Nature Reviews Gastroenterology and Hepatology reports that several genes have been isolated as potential contributors to the hereditary nature of alcoholism. Many people with alcohol use disorder hesitate to get treatment because they don’t recognize that they have a problem. An intervention from loved ones can help some people recognize and accept that they need professional help.
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.
Genome-wide Association Studies
Like many other complex traits, alcoholism appears to be clinically and etiologicaly hetrogenous[13]. This implies that there might be several steps and intermediate conditions in the development of AUD. Information about the underlying genetic factors that influence risk to AUD can be derived from https://trading-market.org/most-people-with-alcohol-and-drug-addiction/ multiple levels of AUD including amounts of drinks (Alcohol consumption), severity and symptoms of alcohol abuse and dependence. Commonly, genome wide association studies (GWAS) of alcoholism have focused on phenotypes based on the Diagnostic & Statistical Manual of Mental Disorders (DSM)[14].
- Scientists most highly observe this increase in women, rural citizens, those with lower socioeconomic status, and minorities.
- In this way, ADH1B and ALDH2 are hereditary factors that actually reduce the risk of developing alcoholism.
- If your body reacts poorly to moderate amounts of alcohol, you’re less likely to develop AUD.
The GI tract is exposed to very high levels of alcohol as it passes through
the mouth, esophagus, stomach and intestinal tract, and most ethanol passes through
the liver before entering the circulation. Alcohol levels in common drinks range
from approximately 5% (1.1 M) for beer, 11-15% for wine (∼3
M) and 40% for spirits (∼9 M). The oral cavity and esophagus are
directly exposed to those levels, and the liver is exposed to high levels from the
portal circulation. Thus it is not surprising that diseases of the GI system,
including cirrhosis, pancreatitis, and cancers of the upper GI tract are affected by
alcohol consumption80-86. They are essential in influencing the brain’s function and response to addictive substances like alcohol.
Is Alcohol Abuse Hereditary? Why Alcoholism May be Inherited
In some instances, the person may not even realize the mental health condition is present. These underlying causes can also be genetic, and if there is a family member that never received treatment for their mental health condition, other family members may never realize they have a mental health disorder as well. Environmental influences may also prevent the expression of their Transactional Writing: Letters That Heal inherited genes. The role of a person’s environment in AUD shows differences when comparing people with parents addicted to alcohol versus other family members.

- This progression, continuing until the individual hits the bottom with excessive drinking and then moves back up to rehabilitation, is called the Jellinek curve.
- Psychological, social, and environmental factors also influence the likelihood of developing the addiction.
- It is, however, an addictive substance, and problematic use can lead to both alcohol dependence and the onset of alcoholism.
- On the other hand, not having genes linked to alcoholism doesn’t mean you won’t develop an addiction.
- A second approach that will likely benefit the alcohol research
community will be greater examination of pathways or gene sets. - Your genetic risk refers to the likelihood that specific genes or genetic variants passed down to you will lead to a particular condition.
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. The world around you also can play a significant role in opening a door that leads to problematic substance use, notes Dr. Anand. Genetic differences in tolerance or liver degradation capacity can also genetically influence the condition. Mental illness increases the likelihood of developing alcoholism by 20% to 50%.
Environmental Risk Factors for Alcoholism
If a child sees their parents drinking, or if there is no parental supervision over the consumption of alcohol, then it is likely that they may develop an unhealthy relationship with alcohol later on in life. Children begin to see this as just another daily activity and therefore are less concerned about overall risk. There are also gene variants that can predispose people to develop a mental health disorder like bipolar disorder or schizophrenia.
