Alcohol Addiction: Causes, Symptoms, Stages and Treatment
Alcohol addiction, clinically called Alcohol Use Disorder (AUD), is a chronic, relapsing brain disorder characterised by compulsive alcohol use, loss of control over drinking, and negative emotional states when not drinking. It ranges from mild to severe and is diagnosed when two or more of eleven clinical criteria are met within a twelve-month period. AUD is a treatable medical condition, and recovery is achievable with the right professional support.
Key facts
- Alcohol Use Disorder (AUD) is diagnosed under the DSM-5 when a person meets 2 or more of 11 criteria within a 12-month period; mild AUD is 2-3 criteria, moderate is 4-5, and severe is 6 or more.
- Genetic factors account for approximately 50% of a person’s risk of developing AUD, according to research published by the National Institute on Alcohol Abuse and Alcoholism (NIAAA).
- Alcohol activates the brain’s dopamine reward system; over time, the brain reduces its natural dopamine output, meaning more alcohol is required to feel normal.
- Beginning to drink before the age of 15 significantly increases the lifetime risk of developing AUD compared with those who start drinking at 21 or older.
- Over 31% of South Africans over the age of 15 drink, and alcohol misuse rates in South Africa are among the highest in the world by per-capita consumption.
- Alcohol abuse causes liver disease (including cirrhosis), increases the risk of at least six types of cancer, and can cause permanent neurological damage including Wernicke-Korsakoff syndrome.
- Alcohol withdrawal can be medically dangerous, including the risk of seizures; supervised medical detox is the safest first step in treatment for those with physical dependence.
Understanding Alcohol Use Disorder
Alcohol Use Disorder is not simply drinking too much on occasion. It is a recognised medical condition in which a person’s relationship with alcohol becomes compulsive, physically entrenched, and resistant to willpower alone. Rehab Helper South Africa connects individuals and families to accredited rehabilitation programmes across Johannesburg, Cape Town, Durban and Pretoria, with addiction counsellors available 24/7 to guide the first step.

Alcohol Abuse vs Alcohol Dependence
These two terms describe different points on the same spectrum. Alcohol abuse is a pattern of drinking that causes harm to health, relationships or responsibilities, even without physical dependence. Examples include drinking regularly to cope with stress, binge drinking at weekends, or missing work because of alcohol. Alcohol dependence, or AUD, goes further: the body and mind have adapted to alcohol, producing tolerance and withdrawal symptoms when drinking stops.
The DSM-5 diagnostic threshold is clear: two or more of eleven criteria within a twelve-month period constitutes AUD. Mild AUD involves two to three criteria, moderate involves four to five, and severe involves six or more. A trained addiction counsellor can help you or a loved one understand where on this spectrum the current situation sits.
The Five Stages of Alcohol Abuse
Alcohol problems rarely appear overnight. They develop through recognisable stages, and identifying the current stage is the first step toward choosing the right level of care.
- Occasional abuse and binge drinking – experimental or social use that begins causing problems, such as risky behaviour or blackouts.
- Increased drinking – drinking more frequently, using alcohol to manage emotions such as anxiety, stress or loneliness.
- Problem drinking – alcohol begins to interfere with daily responsibilities, relationships and physical health.
- Alcohol dependence – physical tolerance develops; stopping or reducing drinking causes withdrawal symptoms such as tremors, sweating and anxiety.
- Addiction (severe AUD) – compulsive use continues despite serious consequences to health, employment and family; professional treatment is required.
Progression through these stages is not inevitable, and intervention at any stage can prevent advancement to severe AUD.
Causes and Risk Factors of Alcohol Use Disorder
Alcohol activates the brain’s reward system by releasing dopamine, creating feelings of pleasure that reinforce repeated use. Over time, the brain adapts by reducing its natural dopamine production, meaning more alcohol is needed to feel normal. This neurological shift is the biological core of addiction, not a character flaw.
Genetic factors account for approximately 50% of AUD risk. The remaining risk is shaped by environment and experience. Key risk factors include:
- Family history of AUD
- Mental health conditions such as depression, anxiety or PTSD
- History of trauma or adverse childhood experiences
- Starting to drink before the age of 15
- High-stress environments or occupations
- Peer influence and early social exposure to heavy drinking
What Alcohol Abuse Does to a Person
Chronic alcohol misuse affects nearly every system in the body and significantly alters behaviour and mental health. The consequences are not abstract; they are measurable and, in many cases, progressive.
Physical Health Effects
- Liver disease: fatty liver, alcoholic hepatitis and cirrhosis
- Increased risk of cancers of the mouth, throat, oesophagus, liver, colon and breast
- Cardiovascular damage: cardiomyopathy, irregular heartbeat and high blood pressure
- Neurological damage: memory loss, peripheral neuropathy and Wernicke-Korsakoff syndrome
- Weakened immune system, increasing susceptibility to infections
Mental and Behavioural Effects
- Depression and anxiety worsen over time, despite short-term relief from drinking
- Increased risk of suicidal ideation and self-harm
- Relationship breakdown, job loss and financial harm
- Cognitive impairment affecting decision-making, impulse control and memory
Recognising the Symptoms of Alcohol Addiction
The most common symptoms of alcohol addiction include craving alcohol, being unable to stop once drinking starts, experiencing withdrawal when not drinking, and continuing to drink despite clear harm. The DSM-5 identifies eleven criteria in plain terms:
Behavioural Symptoms
- Drinking more, or for longer, than intended
- Repeated failed attempts to cut down or stop
- Spending a large amount of time obtaining, using or recovering from alcohol
- Giving up important activities because of drinking
- Continuing to drink despite it causing problems in relationships or at work
Physical Symptoms
- Needing more alcohol to achieve the same effect (tolerance)
- Experiencing withdrawal symptoms such as sweating, shaking or nausea when not drinking
- Drinking to relieve or avoid withdrawal symptoms
Psychological Symptoms
- Strong cravings or urges to drink
- Continuing to drink despite knowing it is worsening a physical or mental health condition
- Drinking in situations where it is physically hazardous
If you recognise two or more of these in yourself or someone you care about, speaking to an addiction counsellor is the right next step.
Treatment Options and Recovery in South Africa
Alcohol addiction is a treatable medical condition. Most people with AUD benefit from some form of treatment, and many achieve long-term sobriety. The appropriate level of care depends on the severity of AUD, physical health, and personal circumstances.
The main treatment pathways are:
- Medical detox – supervised withdrawal to manage potentially dangerous symptoms, including seizures; always the first step for those with physical dependence.
- Inpatient rehabilitation – residential programmes providing structured therapy, medical support and peer community, typically lasting 28 to 90 days; suited to severe AUD or previous relapses.
- Outpatient rehabilitation – structured treatment while living at home, including intensive outpatient programmes (IOP); suitable for mild to moderate AUD or those with work and family obligations.
- Medication-assisted treatment (MAT) – medications such as naltrexone, acamprosate and disulfiram reduce cravings and relapse risk under medical supervision.
- Therapy – Cognitive Behavioural Therapy (CBT) and motivational interviewing are the most evidence-based psychological approaches for AUD.
- Support groups – Alcoholics Anonymous (AA) and SMART Recovery provide ongoing peer support during and after formal treatment.
