What Is Alcoholism?
As the National Institute on Alcohol Abuse and Alcoholism (NIAA) defines it, alcohol use disorder is simply, uncontrolled and problematic drinking. More explicitly, an addiction to alcohol is a chronic illness marked by an inability to control or stop drinking alcohol despite the harm it’s posing to your health, job or school, relationships and social life.
According to the NIAA, over 5% of the U.S. population struggles with AUD (Alcohol Use Disorder). Alcohol addiction also negatively affects the loved ones and caregivers of each person with this disorder—negatively impacting an incalculable number of human lives.
Identifying Alcoholism
Alcoholism can be hard to spot—but understanding how it happens and what it looks like can make it easier to get help.
Alcohol addiction doesn’t happen all at once. It usually develops gradually as drinking becomes more frequent, more routine, and more difficult to stop.
What begins as social or occasional drinking can evolve into dependency when alcohol starts to feel necessary for managing stress, escaping negative emotions, or just getting through the day. Over time, the brain adapts—making you crave alcohol more and making it harder to feel normal without it.
There’s no single cause of alcoholism, but some people are more likely to develop it than others. Risk factors include a family history of addiction, a personal history of trauma or mental illness, early exposure to alcohol, and social environments that normalize heavy drinking.
These factors can combine to increase your chances of developing alcohol use disorder—especially if drinking becomes a way to cope.
Alcoholism can be hard to recognize at first—but there are clear warning signs to watch for. These include needing to drink more to get the same effect, feeling unable to cut back, missing work or school because of drinking, or continuing to drink despite negative consequences.
If alcohol use is affecting your relationships, health, or responsibilities, it may be time to take a closer look.
Alcohol affects nearly every part of your body—and the effects can be severe. Organs and systems that may be impacted include your:
- Brain
- Heart
- Bones
- Digestive Systems
- Endocrine Systems
- Immune System
- Nervous System
- Reproductive System
The symptoms of alcoholism can vary, but often include cravings, loss of control, withdrawal symptoms, and continued drinking despite the harm it causes. You might prioritize drinking over everything else, struggle with guilt or shame, and feel unable to function without alcohol. Recognizing these symptoms is a key first step toward getting help and finding recovery.

Frequently Asked Questions
As the National Institute on Alcohol Abuse and Alcoholism (NIAA) defines it, alcohol use disorder is simply uncontrolled and problematic drinking.
More explicitly, an addiction to alcohol is a chronic illness marked by an inability to control or stop drinking alcohol despite the harm it’s posing to your health, job or school, relationships and social life.
There isn’t just one kind of alcohol use disorder. According to the published report Classification of Alcohol Use Disorders, AUD comes in several forms. One type, alcoholism or alcohol dependence, occurs when you no longer have control over your drinking; another type, alcohol misuse, occurs when your drinking has repeated significant consequences.
Alcohol triggers the brain to release dopamine, the chemical associated with the brain’s reward system. This causes the brain to associate drinking with positive feelings, making you want to drink more. According to a 2020 study published in the Journal of Neuroscience, alcohol consumption also impacts the hormone serotonin, which is involved in key functions and factors like sleep and mood.
As your drinking increases in quantity, frequency or duration, the pleasure you experience from drinking lowers over time. You can develop a tolerance for alcohol and may experience withdrawal symptoms when you reduce or cease drinking. Eventually, you may start drinking more to stave off withdrawal symptoms, leading to a cycle that is difficult to break without professional help.
Health experts recommend that those who choose to drink alcohol do so in moderation. If you’re male, you should drink no greater than two drinks daily, and heavy drinking is considered anything more than 14 drinks in a given week or four in a given day. Females should drink no greater than one drink daily, and heavy drinking is considered anything more than seven drinks in a given week or three drinks in a given day.
One drink is equal to
- 12 oz. of beer
- 8 to 9 oz. of malt liquor
- 5 oz. of wine
- 1.5 oz. of distilled spirits or hard liquor such as vodka, tequila, rum or whiskey
Knowing your limits is important to maintaining a healthy and responsible balance when it comes to alcohol use. If you are prone to alcoholism due to family history or previous addictions, any alcohol use is risky and should be avoided. Those who find themselves or a loved one struggling with addiction should reach out for professional help. A qualified treatment provider can assist you in overcoming your addiction and maintaining your sobriety over the long term.
