The main risk factors for an alcohol use disorder are a family history of alcohol problems, starting to drink at a young age, a mental health condition such as depression or anxiety, a pattern of heavy or binge drinking, and an environment where drinking is frequent and easy to reach. None of these guarantees addiction, and people without any of them can still develop one, but the more that apply, the higher the risk. Knowing which apply to you or someone you love is a practical way to gauge how careful to be with alcohol, and when it may be time to get help.
Risk factors for an alcohol use disorder
Family history and genetics
Alcohol use disorders run in families, and genetics account for a meaningful share of the risk. Growing up around a parent who drinks heavily adds an environmental layer on top of the inherited one. Having a close relative with an alcohol problem does not make addiction inevitable, but it is one of the strongest known risk factors, and it is a reason to be especially careful with alcohol.
Drinking at a young age
People who begin drinking in their teens are more likely to develop an alcohol use disorder later than those who start in adulthood. The developing brain is more vulnerable to alcohol’s effects, and early heavy drinking can set patterns that are hard to break.
Mental health conditions
Depression, anxiety, trauma, and other mental health conditions raise the risk of alcohol addiction, in part because some people drink to cope with difficult feelings. Alcohol and mental health tend to feed each other: drinking can deepen depression and anxiety, which can drive more drinking. When both are present, treating them together, as co-occurring conditions, works better than treating either alone.
Heavy and binge drinking
How much and how a person drinks matters. Government guidelines describe moderate drinking as up to one drink a day for women and up to two for men. Binge drinking, commonly defined as roughly four or more drinks for women or five or more for men in about two hours, and frequent heavy drinking both raise the risk that alcohol use will progress into a disorder.
Environment and access
Where and how a person lives shapes their risk. Regular exposure to heavy drinking among friends or family, high stress, and easy access to alcohol all make problem drinking more likely. Social settings that treat frequent heavy drinking as normal can mask a developing disorder.
The clearest risk profile is someone who carries several of these at once, for example a person with a family history who started drinking young and drinks to manage anxiety. If that describes you or someone close to you, it is worth paying attention to how alcohol fits into daily life.
What an alcohol use disorder is
An alcohol use disorder is the clinical term for what many people call alcoholism: a medical condition in which a person keeps drinking despite harm to their health, relationships, or responsibilities. It is diagnosed with the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), which lists 11 criteria. Meeting two or three suggests a mild disorder, four or five a moderate one, and six or more a severe one. A person only needs to meet two of the eleven to be diagnosed.
Signs and symptoms
The criteria describe patterns you can recognize in everyday life:
- Craving alcohol, or thinking about it often
- Wanting to cut down and not being able to
- Drinking more, or for longer, than intended
- Spending a lot of time drinking or recovering from drinking
- Trouble at work, school, or home because of alcohol
- Continuing to drink even when it causes health or relationship problems
- Giving up activities that used to matter in favor of drinking
- Needing more alcohol to feel the same effect (tolerance)
- Experiencing withdrawal symptoms, such as shaking, sweating, or nausea, when not drinking
Someone who shows several of these likely has an alcohol use disorder and would benefit from a professional assessment.
Why an alcohol use disorder is worth taking seriously
Alcohol misuse carries real consequences, and they reach well beyond the person drinking. Understanding them is part of understanding why treatment matters.
Health effects
Over time, heavy drinking raises the risk of liver disease, including cirrhosis, along with several cancers, high blood pressure, heart problems, and damage to the digestive and nervous systems. Alcohol also disrupts sleep, mood, and memory. Many of these harms build quietly over years, which is part of what makes an alcohol use disorder easy to underestimate until the damage is advanced.
Effect on families and children
Alcohol misuse strains relationships and is especially hard on children in the home. Research has linked a parent’s heavy drinking to emotional and behavioral difficulties in their children, lower school performance, and damaged trust between parent and child. The effects can start even before birth, since drinking during pregnancy can cause fetal alcohol spectrum disorders. None of this is said to assign blame; it is why treating an alcohol use disorder often helps a whole family, not just one person.
Safety and daily life
Alcohol is a factor in a large share of accidents, injuries, and violence, including impaired driving and harm within relationships. It also erodes work and finances as drinking takes up more time and attention. The point of laying this out is not to frighten anyone, but to underline that an alcohol use disorder is a legitimate medical condition with serious stakes, and that treatment genuinely helps.
Getting a diagnosis
A diagnosis comes from a professional, such as a primary care physician, psychologist, psychiatrist, or addiction specialist, using the DSM-5 criteria. It is not a judgment of character; it simply identifies the problem so that treatment can be matched to its severity, and it is what allows care to be billed to insurance. If you are unsure whether your drinking has crossed a line, an honest conversation with a clinician is the place to start.
How an alcohol use disorder is treated
Treatment is tailored to the person, and for anyone who is physically dependent on alcohol it usually begins with detox.
Medically supervised detox
Because alcohol withdrawal can be dangerous, the safest way to stop after a period of heavy drinking is under medical care. In a medically supervised detox, a clinical team keeps the person safe and as comfortable as possible while the body clears the alcohol. Withdrawal symptoms tend to appear within 6 to 12 hours of the last drink and can include tremors, sweating, nausea, and shaking. In a minority of cases they escalate to seizures or delirium tremens, which is why supervision matters. Alcohol detox usually runs about 3 to 7 days, set by clinical need.
Ongoing treatment
Detox handles the physical side of stopping, but it does not by itself change the reasons a person was drinking, so it is a first step rather than a cure. After detox, most people continue in residential or outpatient treatment, where the work shifts to understanding and changing the patterns behind the drinking.
Ongoing treatment usually blends several approaches. Individual and group therapy give people a place to work through triggers and learn new ways to cope with stress. Cognitive behavioral therapy, one of the better-studied approaches for alcohol use, helps a person recognize and change the thoughts that feed drinking. Peer support such as Alcoholics Anonymous adds accountability and community from others who have been through it. Where appropriate, doctors may also prescribe medications approved to support alcohol recovery, which can reduce cravings or make drinking less rewarding. The right mix depends on the severity of the disorder, on whether there are co-occurring mental health conditions, and on what fits a person’s life. Relapse risk is highest in the first several months, which is why aftercare and continued support matter well past the end of formal treatment.
Frequently asked questions
Is alcoholism the same as an alcohol use disorder?
Effectively, yes. “Alcoholism” is the everyday word; “alcohol use disorder” is the clinical term used to diagnose it. When people say someone is an alcoholic, they usually mean a person who meets the criteria for an alcohol use disorder.
What are the biggest risk factors for alcoholism?
A family history of alcohol problems, starting to drink young, mental health conditions, and a pattern of heavy or binge drinking are among the strongest. Environment and easy access add to the risk. Having risk factors does not mean addiction is certain, and not having them does not make a person immune.
Can you have an alcohol use disorder without drinking every day?
Yes. The diagnosis is based on the pattern and consequences of drinking, not on a daily count. Someone who drinks heavily only on weekends can still meet the criteria if alcohol is causing problems and they keep drinking anyway.
What happens to your body when you stop drinking?
After a period of heavy drinking, stopping can bring withdrawal symptoms as the nervous system rebalances, ranging from tremors and insomnia to, in more serious cases, seizures and delirium. This is exactly why stopping under medical supervision is safer than doing it alone.

Frequently Asked Questions
What is alcohol use disorder (AUD)?
Alcohol use disorder is the clinical term for the medical condition formerly described as alcoholism. It is diagnosed by patterns including loss of control over drinking, continued use despite consequences, tolerance, and withdrawal symptoms.
How is AUD different from alcoholism?
AUD is the modern, clinical, person-first term used in the DSM-5 and by major medical organizations. Alcoholism is the older non-clinical term. The shift reflects an understanding that AUD is a medical condition on a spectrum from mild to severe — not a character flaw.
What are the signs of alcohol use disorder?
Common signs include drinking more or longer than intended, unsuccessful attempts to cut back, strong cravings, continued drinking despite job, family, or health consequences, tolerance increases, and withdrawal symptoms when not drinking.
Is AUD treatable?
Yes. Medical detox to manage withdrawal safely, residential or outpatient therapy (CBT, DBT, motivational interviewing), medications (naltrexone, acamprosate, disulfiram), and long-term support are all part of effective treatment. Outcomes improve significantly with longer continuum of care.
Can someone with AUD recover?
Many people with AUD reach long-term, sustained recovery. Recovery is not a single event — it involves treatment, ongoing support, often medication, and lifestyle change. The clinical evidence is strong that recovery is achievable for most people who engage in care.
Does insurance cover AUD treatment?
Yes. The Mental Health Parity and Addiction Equity Act requires most plans to cover AUD treatment comparably to other medical conditions. Confidential verification at (855) 981-8935.
