Key Points on Alcohol Withdrawal
Alcohol Withdrawal Syndrome (AWS) is the body’s reaction to reduced or stopped alcohol intake in people who are alcohol-dependent. Mild to severe symptoms include hand tremors, sweating, insomnia, hallucinations, and seizures. Delirium Tremens (DTs) is a serious life-threatening form of withdrawal that requires immediate medical intervention. Diagnosis often involves assessing your health history, symptom severity, and laboratory tests to rule out other conditions. Treatment may include medications like benzodiazepines, psychosocial support, and medical supervision to ensure a safe detox. Why Alcohol Withdrawal Occurs
Alcohol acts as a central nervous system depressant, slowing down brain activity by enhancing the inhibitory effects of the neurotransmitter gamma-aminobutyric acid (GABA) and suppressing excitatory pathways. When someone drinks heavily over a long period, the brain adapts by changing how it responds to these chemical signals.
Once alcohol intake is suddenly cut off, the brain can become hyperactive, leading to Alcohol Withdrawal Syndrome (AWS). The more a person drinks on a regular basis, and the longer they’ve been drinking, the greater the risk of developing withdrawal symptoms when they stop drinking.
Your body, accustomed to regular alcohol intake, will experience a range of symptoms as it adjusts to the absence of alcohol. These can vary widely in severity and often include both physical and psychological effects.
Withdrawal symptoms typically begin 8 to 24 hours after the last drink. For some people, these symptoms remain mild, but for others, withdrawal can quickly escalate. Recognising the early warning signs and seeking professional help can be lifesaving.
Typical Alcohol Withdrawal Symptoms
There are many different types of withdrawal symptoms and they can start as early as six hours after stopping drinking.
- Nausea
- Vomiting
- Anxiety
- Shaky hands
- Sweating
- Insomnia
- Headache
- Hallucinations
- Seizures
2-5 days after drinking, you may experience the following withdrawal symptoms:
- Delirium tremens and shaking
- Dehydration
- Rapid heartbeat
- High blood pressure
- Confusion
- Loss of consciousness
- Angry or nervous behaviour
- Sweating
- Lack of sleep

Around 5 days after your last drink, your withdrawal symptoms are likely to start easing off. However, a small number of people will continue to experience withdrawal symptoms for several weeks, and some severe withdrawal symptoms may be life-threatening.
Severe Symptoms & Delirium Tremens (DTs)
For some people, withdrawal may progress into severe or life-threatening forms:
Hallucinations: Visual, auditory, or even olfactory hallucinations can appear a day or two after the last drink. Seizures: Alcohol-related seizures typically occur between 12 and 48 hours after the final drink and can be a precursor to DTs. Delirium Tremens (DTs): Usually emerging 2 to 3 days into withdrawal, DTs include severe tremors, hallucinations, confusion, agitation, and critical changes in vital signs (like tachycardia and hypertension). Early detection and treatment are crucial, as DTs carry a significant risk of morbidity and even death. 
Diagnosis of Alcohol Withdrawal
Diagnosing Alcohol Withdrawal Syndrome involves assessing a person’s overall health, history of alcohol use, and whether they’ve had withdrawal episodes before. While there isn’t a single test for AWS, doctors may order blood work or heart tests to rule out other issues.
Medical professionals also refer to the DSM-5 criteria for diagnosing withdrawal, which include:
A reduction or cessation of heavy, prolonged alcohol use. A set of withdrawal symptoms not explained by another medical or mental health disorder. Understanding these factors helps in creating an appropriate treatment plan and ensuring that any other complications are properly managed.
Who Is at Risk of Severe Withdrawal?
While anyone who drinks heavily over time can develop withdrawal symptoms, certain factors increase vulnerability:
Heavy, Prolonged Use: The larger the daily intake and the longer the duration, the higher the dependency risk. Previous Withdrawals: A history of severe withdrawal or delirium tremens (DTs) indicates a higher risk for future severe episodes. Concurrent Health Issues: Co-occurring medical or mental health conditions can exacerbate withdrawal severity. According to some estimates, around 5-6% of hospitalised patients with Alcohol Use Disorder (AUD) experience AWS, underscoring the seriousness of the condition.

Standard Treatments for Alcohol Withdrawal
The severity of withdrawal determines the level of care required. Mild to moderate cases may be managed on an outpatient basis with close monitoring, while severe cases require hospitalisation or a specialised detox facility. Common treatments include:
Benzodiazepines (e.g., chlordiazepoxide, diazepam, lorazepam): These medications mimic alcohol’s effects on the brain, reducing the risk of seizures and easing anxiety and insomnia. Gabapentin: Can improve sleep, stabilise mood, and decrease cravings. Supportive Care: Monitoring hydration, electrolytes, and vital signs is essential, especially for patients at risk of complications. Gamma-hydroxybutyric acid (GHB) and Sodium oxybate (SMO): Sometimes used in severe AWS cases or within specialised settings.
Mild Alcohol Withdrawal
If you detox at home without medical supervision some basic steps can help:
- Soft lighting
- Healthy foods
- Plenty of fluids
- Quiet surroundings
- A positive, supportive atmosphere
If you start to experience severe withdrawal symptoms such as a rise in your body temperature, pulse or blood pressure, or if you start experiencing hallucinations and seizures, you should seek medical care immediately.
Medically Assisted Withdrawal (MAW)
Also known as a planned detoxification under medical supervision, MAW often combines medication with psychosocial support. Clinicians may adopt symptom-triggered approaches using scales like the Glasgow Modified Alcohol Withdrawal Scale or the Minnesota Detoxification Scale (MINDS) to tailor care.
Medication: Dosages are adjusted based on withdrawal severity. Counselling and Therapy: Helps patients address the psychological aspects of addiction. Risk-Benefit Assessment: The advantages of controlled detox must be weighed against potential risks, ensuring the safest path for each person.
Potential Complications of Alcohol Withdrawal
When untreated or poorly managed, alcohol withdrawal can result in complications such as:
Seizures and other neurological issues. Wernicke’s Encephalopathy: A serious condition linked to thiamine deficiency, presenting with confusion, ataxia, and eye movement abnormalities. Alcohol Withdrawal Psychosis: Characterised by delirium, paranoia, or a disconnect from reality. Neuropsychological Impairment: Repeated withdrawals can damage cognitive function over time, affecting memory and decision-making. Gastrointestinal Issues: Chronic alcohol use can harm the GI tract, sometimes causing diarrhoea or malabsorption. Ruling out any co-occurring withdrawals (e.g., from drugs) or other medical problems is critical to providing effective treatment.
Seeking Help and Support
If you or a loved one may be dependent on alcohol, early intervention is crucial. The following resources can help:
GP or Local Alcohol Services: A primary care doctor can guide you to detox programmes and specialised services. Frank (0300 123 6600): Offers advice on substance use, including alcohol. Charities and Private Organisations: Provide additional treatment options, often with shorter wait times. Support Groups: Organisations such as Alcoholics Anonymous (AA), We Are With You, Drinkline, and Drinkchat offer ongoing peer and professional support.
A well-structured plan that combines medical supervision, counselling, and long-term support can greatly increase the likelihood of successful, sustained recovery.
