Alcohol Use Disorder: Signs, Health Risks, and Treatment
Alcohol use disorder (AUD) is one of the most common — and most underdiagnosed — substance use disorders. Because drinking is socially accepted, problems can be easy to overlook until they become serious. The good news: AUD is a medical condition with effective, evidence-based treatments. This guide covers the signs, the risks, and the paths to recovery.
What alcohol use disorder is
Alcohol use disorder is a medical condition characterized by an impaired ability to stop or control alcohol use despite negative consequences. It ranges from mild to severe and, like other substance use disorders, involves changes in the brain that make drinking feel necessary. It is not a matter of willpower or character.
Signs to watch for
- Drinking more, or for longer, than intended, and being unable to cut down.
- Strong cravings, and spending a lot of time drinking or recovering from drinking.
- Needing more alcohol to feel the same effect (tolerance).
- Experiencing withdrawal — shakiness, sweating, anxiety, nausea — when not drinking.
- Continuing to drink despite problems with health, work, or relationships.
- Giving up activities, or drinking in risky situations.
If several of these are present, it is worth seeking a professional assessment. The number of symptoms helps determine whether the disorder is mild, moderate, or severe.
A critical safety warning about withdrawal
This point can be life-saving: for someone who drinks heavily and daily, suddenly stopping can cause dangerous withdrawal, including seizures and delirium tremens (DTs), which can be fatal. Heavy drinkers should not quit 'cold turkey' alone. Medically supervised detox uses medication and monitoring to prevent these complications. If you drink heavily, talk to a medical professional before stopping.
Health risks of long-term heavy drinking
Beyond the immediate dangers, sustained heavy drinking raises the risk of liver disease, heart problems, several cancers, cognitive decline, mental health conditions, and accidents and injuries. The encouraging flip side is that many alcohol-related health harms improve with sustained reduction or abstinence.
Effective treatments
AUD treatment uses the same continuum of care as other substance use disorders — from outpatient counseling to residential treatment — matched to severity. Two pillars deserve special mention:
Medication
Many people do not realize alcohol use disorder can be treated with medication. Three FDA-approved options — naltrexone (reduces craving and the reward of drinking), acamprosate (helps maintain abstinence), and disulfiram (a deterrent) — can be very effective, especially combined with counseling. Ask a provider whether medication is right for you.
Counseling and support
Evidence-based therapies such as cognitive behavioral therapy and motivational approaches help people change their relationship with alcohol, while mutual-aid groups (such as AA or SMART Recovery) provide community and accountability. Treating any co-occurring mental health conditions is also key, since anxiety and depression often accompany AUD.
Recovery is possible at any stage
Whether the goal is reduced drinking or full abstinence, effective help exists, and earlier is better. A professional assessment is the first step toward a plan that fits your situation and goals.
Frequently asked questions
Is it dangerous to stop drinking suddenly?
For heavy, daily drinkers, yes — abrupt withdrawal can cause seizures and delirium tremens, which can be fatal. Heavy drinkers should not quit cold turkey alone and should seek medically supervised detox. Always consult a medical professional before stopping.
Can alcohol use disorder be treated with medication?
Yes. Three FDA-approved medications — naltrexone, acamprosate, and disulfiram — can treat alcohol use disorder, and are often most effective combined with counseling and support.
