What is alcohol addiction?
Alcohol addiction is a disease where a person can’t control or stop their drinking, even when it causes serious harm to themselves and those around them. It affects everything from a person’s mental and physical health to their relationships. It’s also known as alcohol use disorder (AUD) or alcoholism.
Alcohol addiction can still be misunderstood and is often portrayed in unhelpful ways in the media and popular culture. People sometimes see it as a lack of willpower, or assume it could never happen to them. But alcohol addiction is a recognised medical condition that affects millions of people worldwide. This includes people who are struggling themselves or people who are watching a person they love go through it. With the right support, it’s something people can and do recover from.
The difference between alcohol addiction, AUD, and alcoholism
You may have come across several different terms used to describe a person’s harmful relationship with alcohol. They usually mean the same thing, but are used in different ways and in different contexts.
Alcohol use disorder (AUD)
Alcohol use disorder, or AUD, is the clinical term that doctors use to diagnose a person’s issues with alcohol. It covers what people used to call alcohol abuse, but that word puts the blame on the person, which is why it’s no longer used in medical settings. AUD is diagnosed as mild, moderate, or severe. Remember that you don’t need to be at your lowest point to seek help. If drinking is causing distress in any way, that’s reason enough to reach out.
Alcohol addiction
Alcohol addiction is the everyday term most people use, and it generally refers to the more severe end of the AUD spectrum. It’s where drinking has become compulsive and often comes with physical dependence, meaning the body has adapted to alcohol and needs it to function.
Alcoholism
Alcoholism is an older, informal term that’s no longer used in clinical settings but is still common in everyday conversation and in recovery communities like Alcoholics Anonymous (AA). The word “alcoholic” can feel stigmatising to some. But for many people in recovery, particularly those in 12 Step programmes, it’s an important and meaningful part of their journey.
“I've been nearly three years without drinking. Life has become much more enjoyable, I mean life is much more exciting, it’s much more liberating. I just feel complete freedom. I don't need to worry.”
What makes alcohol addictive?
To understand what makes alcohol addictive, it’s important to understand how alcohol affects the brain. Alcohol triggers the release of dopamine, the brain’s reward chemical. With heavy, repeated drinking, the brain’s reward system becomes less responsive. It begins to produce less dopamine on its own and relies more on alcohol to create a sense of relief. This is why alcohol can start to feel less like a choice and more like a need.
The brain’s stress systems can also become overactive, so without alcohol, ordinary situations can feel more anxious than before. This also creates a need for alcohol that wasn’t there before.
What are the signs of alcohol addiction?
Addiction to alcohol can affect you physically, emotionally, or in how you behave. Not everyone will experience all of these signs. But recognising even a few of them can be an important first step in understanding whether alcohol has become a problem.
Alcohol addiction symptoms can include:
Behavioural signs of alcohol addiction
- Finding it hard to cut down or stop, even if you promised you would
- Losing control when drinking
- Spending a lot of time drinking, recovering from drinking, or thinking about the next drink
- Drinking even when it’s negatively affecting your life
- Letting alcohol take priority over responsibilities at home or at work
- Drinking alone or in secret, being dishonest about how much you’re drinking
Physical signs of alcohol addiction
- Needing more alcohol than before to feel the same effect
- Shaking, sweating or feeling sick when alcohol wears off
- Feeling anxious when alcohol wears off
- Blacking out when drinking
- Poor sleep
- Changes in weight
- Frequent stomach pain
- In more severe cases: repeated injuries, falls, infections, or serious health problems like pancreatitis or liver disease
Emotional signs of alcohol addiction
- Strong urges or cravings to drink that feel hard to ignore
- Feeling low, irritable, or restless when you’re not drinking
- Drinking to cope with stress, anxiety, low mood, or difficult memories
- Feeling guilty or ashamed about your drinking, but carrying on anyway
- Hiding how you’re really feeling from the people around you
- A growing sense that you’re not yourself, or that alcohol has become tied to how you feel about who you are

Alcohol addiction treatment is available to you
Castle Health have a variety of inpatient and outpatient clinics across the UK and Europe.
How much do you have to drink to have an addiction to alcohol?
The clinical diagnosis of AUD is based on the impact drinking has on your life and the symptoms you experience, not on a specific quantity or frequency of drinking. You might drink every day, or only at weekends, or even manage to stop for periods of time on your own. But alcohol addiction is a progressive and relapsing condition, which means that without the right support, drinking tends to get worse.
What is functional alcoholism?
When someone appears to be functioning well, it can make it harder to recognise that there’s a problem with alcohol, both for the person themselves and for those around them. If you’re meeting your responsibilities and holding things together on the outside, it can be easy to dismiss concerns or tell yourself that things aren’t that bad. This is known as functional alcoholism.
But functioning on the outside doesn’t mean someone isn’t struggling. It can sometimes mean that problems go unaddressed for longer.
Why is it hard to recognise alcohol addiction?
Cultural messages, misinformation, and the nature of addiction itself can make it difficult to see your drinking clearly.
Stigma and mixed messages
Heavy drinking is often shown as normal or glamorous in films, adverts, and social situations. At the same time, there’s a lot of stigma and misunderstanding about alcohol problems. This can make it confusing to know when drinking has become a problem.
There is no single picture of what alcohol addiction looks like, no typical age, no typical amount, and no typical pattern of drinking.
Denial in alcohol addiction
It’s common for people to be in denial about their drinking. Many people say they didn’t think they were bad enough, or find that they had been minimising what they were going through without realising it. Memory can also be affected, as the brain often suppresses or blocks out the most painful or difficult experiences.
Why do some people not get help?
With increased awareness of what alcohol addiction is, more people are finding the language to describe what they’re going through. There’s also greater awareness among doctors and other health professionals, so that alcohol problems can be identified and addressed early. Still, many people slip through the cracks. Alcohol addiction remains a serious and potentially fatal disease. Not everyone will reach a point where they feel ready to seek help, and recovery is something a person has to want for themselves. That readiness can take time to arrive, and for some it never does.

Why do people become addicted to alcohol?
Some people are more vulnerable to alcohol problems than others, for reasons that are often outside their control. None of this means that someone who has been through these things will develop an addiction to alcohol, or that they can’t recover if they do. But it’s helpful to understand that there are often real reasons why some people are more affected than others.
Family history
Family history can play a part in a person’s relationship with alcohol. If a close family member has struggled with alcohol or other addictions, your own risk can be higher. This doesn’t mean addiction is inevitable, but growing up in surroundings where heavy drinking felt normal can also shape how someone relates to alcohol later in life.
Traumatic events
People who have been through traumatic events such as abuse or grief may be more likely to use alcohol as a way of coping.
Mental health
If you live with anxiety, depression, PTSD, or other mental health problems, you may be more likely to use alcohol to try to feel better. It can bring short-term relief, which is one reason it can become harder to quit.
Other risk factors for alcohol addiction
Other things that can increase vulnerability include starting to drink at a young age, high levels of stress or little support, easy access to alcohol, spending a lot of time in places where heavy drinking is common, and a history of other substance use.
The risks and long-term effects of alcohol addiction
It can be easy to underestimate the damage alcohol causes because it’s legal, but heavy drinking has serious long-term effects on physical and emotional wellbeing. In 2023, the World Health Organisation confirmed that no level of alcohol consumption is safe, linking it to at least seven types of cancer and many other serious health conditions. It’s estimated to contribute to around 3 million deaths globally each year, with the real figure likely higher than records show, as alcohol isn’t always recorded as having had a role, even when it did.
Physical health risks of alcohol addiction
Drinking heavily for a long time can lead to:
- Liver problems, including fatty liver, hepatitis, and cirrhosis
- Heart disease and high blood pressure
- A higher risk of some cancers, such as mouth, throat, liver, and breast cancer
- Pancreatitis and stomach problems
- A weaker immune system and getting infections more often
- Changes in the brain that make it harder to remember things, keep your balance, or think clearly
Some alcohol-related health problems, like liver disease, can go unnoticed for a long time. You might feel fine day to day and only find out something is wrong when you have tests or become very unwell.
Mental health risks of alcohol addiction
Alcohol can affect your mental health in a number of ways.
Anxiety
Alcohol might help you feel less anxious at first, but as it wears off, you can feel more anxious. Some people call this “hangxiety”. If you drink heavily often, it can become harder to manage anxiety without alcohol.
Sleep disruption
Alcohol can help you fall asleep, but it often disrupts deeper, restful sleep later in the night. Poor sleep can affect your mood, concentration, and long-term physical health.
Worsen existing mental health conditions
If you live with depression, bipolar disorder, or PTSD, alcohol can make your symptoms less predictable and make treatment harder. It can also interact with some mental health medicines.
Self-harm and suicidal thoughts
Heavy drinking can increase the risk of self-harm and suicide. When your inhibitions are lower, you might act on upsetting thoughts that you wouldn’t act on when sober.
Dependence
You might start to rely on alcohol to feel calm or comfortable. This can make it hard to manage your emotions without drinking, even if you know alcohol is making things worse.
Isolation and loneliness
Alcohol can put a strain on your relationships, work, and daily routines. This can increase stress and leave you feeling more isolated. Feeling cut off from others can make low mood and other mental health problems worse.
The effect of alcohol addiction on relationships
Alcohol addiction can change how a person behaves in their relationships. While the person struggling with alcohol is often in a great deal of pain, the people around them can be hurting too, as they watch someone they care about change in ways they don’t recognise.
Someone who is kind and reliable when sober may become withdrawn, short-tempered, or unreliable when alcohol is involved. This can be confusing and painful for the people around them. It can wear down trust and make maintaining relationships more difficult.
Success Stories
We’ve helped many people turn their lives around
Do people recover from alcohol addiction?
People do recover from alcohol addiction and go on to live full, meaningful lives. Health, mood, relationships, and daily life can all improve, often in ways people didn’t expect. Recovery is usually a gradual process, and the gains tend to build over time.
Relapse can happen, and it doesn’t mean someone has failed or that their situation is hopeless. There are often warning signs before it occurs, like pulling away from support or slipping back into old patterns. Staying connected to the right support and continuing to use the tools learned in treatment gives people a strong foundation for long-term sobriety.
How to help someone with alcohol addiction
When you’re worried about someone’s drinking, it can be hard to know what to say or where to start. You might be feeling worried, guilty, frustrated, or helpless. All of those feelings are completely understandable. Alcohol addiction affects the whole family, not just the person drinking, and the impact on the people closest to them can be significant.
The most important thing to know is that you can’t force someone to stop drinking. Recovery has to be something they want for themselves, and accepting that can be one of the hardest parts of loving someone with an addiction.
How to talk to about alcohol addiction
When you do feel ready to talk, try to choose a calm moment when they haven’t been drinking. Focus on what you’ve noticed and how you’re feeling, using “I” statements rather than blame, and try to avoid arguing about whether they are or aren’t an alcoholic. If they seem open to it, offer something concrete, like looking into options together or going with them to an appointment.
Avoid enabling addiction
It’s also worth being aware of enabling, which can happen without realising it. Covering for someone, making excuses, or shielding them from the consequences of their drinking can unintentionally make it easier for the problem to continue. This isn’t about blame, as it comes from a place of love, but stepping back from that can be an important part of supporting someone effectively.
Find support for yourself
Getting support for yourself is just as important. Loving someone with alcohol addiction can be exhausting and painful, and you don’t have to navigate it alone. Groups like Al-Anon exist specifically for family members and friends, and many people find them a lifeline. At Castle Health, we also offer family therapy as part of our treatment programmes, because we understand that recovery works best when the people closest to someone are supported too.
Where to get help for alcohol addiction
If you’re concerned about your drinking the first step is to reach out. Not sure who to talk to about alcohol addiction? There are several ways you can do this:
- Speak with your doctor or GP: they may be able to refer you to an alcohol rehab service or tell you what other support is available in your local area.
- Contact support groups: in the UK this includes Alcoholics Anonymous (AA), SMART Recovery and Drinkline who can provide support for free.

FAQs about alcohol addiction
Are alcoholics considered addicts?
Yes, alcoholics are considered addicts. You can become addicted to alcohol in the same way that you can become addicted to drugs. It’s a different substance but the effects on a person’s life, mental and physical health can be just as harmful. Alcoholics can also go to rehab to recover from addiction.
Does alcohol addiction ever go away?
With the right support people with alcohol addiction can live full and happy lives, free from the effects of addiction. But that doesn’t mean that the addiction goes away. People who have experienced alcohol addiction are always at risk of relapse. That’s why lifelong management is important.
Is alcohol addiction a disease?
Yes, alcohol addiction is a disease. Just as with other diseases, some people are more vulnerable to alcohol addiction than others. This can be due to a range of factors including family history, mental health and experiences of trauma. Most importantly, recovery is possible with the right treatment and support.
How long does it take to become addicted to alcohol?
Alcohol addiction can develop slowly over many years of heavy drinking, but it can also develop faster in some people. It depends on your personal circumstances and your relationship with alcohol. How alcohol is affecting your life and health is more important than the length of time you’ve been drinking for. If you recognise the signs of alcohol addiction in your health or behaviour, it’s time to seek help.
How long does it take to overcome alcohol addiction?
Recovery from alcohol addiction depends on each individual. If you choose inpatient rehab, this can last anything from 4 to 12 weeks, followed by ongoing outpatient treatment for as long as you need it. Even once they feel fully recovered, most people continue to attend support groups such as AA throughout their lives to help them avoid a relapse.
