Alcohol withdrawal syndrome is a set of symptoms that occur when someone who is physically dependent on alcohol suddenly stops drinking or reduces their intake. Symptoms can range from mild to severe, with the most severe being life-threatening. The severity and length of alcohol withdrawal vary based on several factors, including the patient's history of alcohol consumption, age, and other medical problems. Symptoms can include insomnia, tremors, mood changes, heart palpitations, increased blood pressure, hallucinations, and delirium tremens. It is important to seek medical advice and monitor withdrawal symptoms as they can be unpredictable and, in some cases, require inpatient treatment.

What You'll Learn
Hallucinations and delirium tremens
Alcohol withdrawal can cause a range of symptoms, from minor to severe. One of the most severe symptoms is delirium tremens (DTs), which is a life-threatening form of alcohol withdrawal. It is characterised by a clouding of consciousness, confusion, disorientation, and hallucinations.
Hallucinations during alcohol withdrawal can be visual, auditory, or tactile, with patients seeing, hearing, or feeling things that seem real but are not actually present. These hallucinations typically emerge within 12 hours to about three days after stopping alcohol use. However, in some cases, symptoms may not appear until up to ten days after discontinuing alcohol. Hallucinations affect approximately 2% of patients experiencing alcohol withdrawal. When accompanied by an altered mental state, hallucinations can indicate the onset of alcohol withdrawal delirium or delirium tremens.
Delirium tremens typically occurs two to four days after an individual's last drink, but it can also appear as early as 48 hours or as late as ten days after the last drink. It is considered a medical emergency with a high mortality rate, historically as high as 20%, but now reduced to around 1% due to advancements in critical care. DTs are more likely to occur in individuals with moderate to severe alcohol use disorder who abruptly stop drinking. The risk factors for developing DTs include concurrent acute medical illness, daily heavy alcohol use, and a history of delirium or mental health issues.
The treatment for delirium tremens typically begins in a hospital setting, where healthcare providers aim to relieve symptoms, reduce the risk of complications, and stabilise the patient's health. Benzodiazepines, a type of sedative, are commonly used to treat DTs as they help calm the excited nervous system. In cases where symptoms cannot be managed with sedatives, anaesthesia may be administered to induce complete sedation until the symptoms subside. Other drugs used to treat acute DTs symptoms include antipsychotic medications, which help prevent hallucinations. Additionally, intravenous fluids with vitamins and minerals may be administered to address dehydration and electrolyte imbalances.
The prognosis for delirium tremens depends on several factors, including the severity of symptoms, the presence of other medical conditions, and the severity of the patient's alcohol use disorder. While DTs can be dangerous, it is a treatable condition, and seeking professional medical guidance and specialised programmes can help individuals lower their alcohol intake or stop drinking entirely to prevent DTs.

Increased heart rate and blood pressure
Alcohol withdrawal can cause a range of symptoms, from mild to severe, and typically affects people with alcohol use disorder (AUD). Symptoms of alcohol withdrawal usually begin within six to 24 hours of stopping or significantly reducing heavy, long-term alcohol use.
Excessive alcohol intake over time can contribute to the development of cardiovascular issues, with the most common being high blood pressure (hypertension). Long-term heavy drinking is associated with an increased risk of various heart diseases, including coronary artery disease, where the blood vessels supplying the heart become narrow or blocked. Chronic alcohol abuse may also lead to persistent irregular heart rhythms, increasing the risk of atrial fibrillation and stroke.
Prolonged heavy drinking can weaken the heart muscle, leading to cardiomyopathy, a condition where the heart is unable to pump blood effectively, resulting in heart failure. Alcohol consumption, especially binge drinking, can cause a temporary rise in heart rate and blood pressure shortly after consumption, with higher alcohol intake resulting in more pronounced effects.
Medical supervision is crucial during alcohol withdrawal, especially for those with a history of severe withdrawal symptoms or those at risk of complications. Beta-blockers are often used to manage increased heart rate and blood pressure.

Tremors and shakes
Tremors, also known as "alcohol shakes", are a common side effect of alcohol withdrawal. They are fits of involuntary shaking that can occur in one area of the body or throughout the whole body. The hands are most commonly affected, but tremors can also be seen in the arms, legs, and other body parts.
Tremors can begin within 5-10 hours of a person's last drink, and typically peak in severity 24 to 48 hours after the last drink. In some rare cases, tremors may not appear until seven to ten days after the last drink, especially for people with a long history of heavy drinking or co-occurring medical conditions. The duration and severity of tremors depend on several factors, including the amount and frequency of alcohol consumption, the overall health of the individual, liver function, general nutrition, and whether the person has experienced withdrawal before.
Alcohol is a central nervous system (CNS) depressant that stimulates the GABAergic system, causing a range of clinical manifestations such as disinhibition, euphoria, and sedation. With chronic alcohol use, the brain adjusts to the alcohol-induced changes in the GABAergic and glutamate systems by producing less GABA and more glutamate to maintain balance. When alcohol intake is stopped or significantly reduced, the brain is left with too little of the calming GABA neurotransmitter and too much of the stimulating glutamate neurotransmitter, resulting in the excitatory symptoms seen in alcohol withdrawal syndrome.
The alcohol shakes can be managed and reduced in several ways. Firstly, maintaining proper hydration is important as alcohol dehydrates the body, which can worsen tremors. Drinking water, electrolyte drinks, or coconut water can help replace lost fluids, but caffeine should be avoided as it can exacerbate tremors. Secondly, blood sugar stabilization is crucial as alcohol disrupts glucose metabolism, leading to low blood sugar, which contributes to the shakes. Consuming small, frequent meals rich in complex carbohydrates, proteins, and healthy fats can help maintain stable blood sugar levels. Thirdly, adequate rest and stress reduction are important. Withdrawal can cause insomnia and anxiety, which can aggravate tremors. Practicing deep breathing, meditation, or light stretching can help calm the nervous system and improve rest.
If tremors are severe or persist for an extended period, it is important to seek medical advice. There are a variety of treatment methods available, including detoxification in a professional treatment center, as stopping alcohol consumption abruptly can lead to dangerous withdrawal symptoms and complications. Benzodiazepines, such as Librium or Valium, are commonly used to manage withdrawal symptoms, including tremors, and lower the risk of developing delirium tremens (DTs). Thiamine (vitamin B1) supplementation can also help reduce tremors and lower the risk of developing Wernicke-Korsakoff Syndrome (WKS), a severe condition associated with alcohol withdrawal that requires immediate treatment.

Anxiety, nervousness, and irritability
Alcohol withdrawal can cause a range of symptoms, from mild to severe, and can even be life-threatening. It affects about 50% of people with alcohol use disorder (AUD) who stop or significantly decrease their alcohol intake. AUD is the most common substance use disorder in the U.S., affecting 28.8 million adults.
Mild anxiety is often an early symptom of alcohol withdrawal, occurring as early as six to 12 hours after the last drink. It can be accompanied by other mild symptoms such as insomnia and a headache. As alcohol withdrawal progresses, anxiety can intensify, leading to nervousness and irritability. This can occur within 24 to 72 hours of the last drink, when symptoms typically peak. During this time, individuals may also experience more severe symptoms, such as hallucinations, tremors, and increased heart rate.
The severity of anxiety, nervousness, and irritability can vary depending on several factors. The degree of alcohol intake, the length of time the individual has been using alcohol, and their previous history of alcohol withdrawal can all influence the intensity of these symptoms. Additionally, underlying medical problems can also contribute to the severity of withdrawal symptoms.
Prolonged withdrawal symptoms, such as insomnia and mood changes, including anxiety, nervousness, and irritability, can last for weeks or even months after the initial withdrawal period. This prolonged phase of withdrawal underlines the importance of comprehensive and ongoing support for individuals undergoing alcohol withdrawal.
It is crucial to seek medical help if you or someone you know is experiencing symptoms of alcohol withdrawal, especially if they are severe or persistent. Treatment options, such as pharmacologic interventions and adjunctive therapies, can help manage these symptoms and improve the chances of a full recovery.

Insomnia and sleep changes
Sleep disturbances during alcohol withdrawal are one of the most common and challenging symptoms experienced. Alcohol withdrawal insomnia can significantly impact recovery and daily functioning, affecting overall quality of life.
Insomnia and sleep disturbances are prevalent during alcohol withdrawal, with studies showing that 36-91% of people with alcohol dependence experience these issues. Sleep problems can be worsened by symptoms of alcohol withdrawal, such as anxiety, agitation, and discomfort, which make it harder to fall asleep and stay asleep. These symptoms can also be intensified by the environment in which withdrawal occurs, with noise, light, and stress being common factors.
The link between alcohol and insomnia is due to the impact of alcohol on the normal sleep cycle. Alcohol disrupts the four stages of sleep, which are light sleep, deep sleep, and rapid eye movement (REM) sleep. Each stage serves an important function for physical and mental restoration. While alcohol can initially make people feel drowsy and fall asleep faster, it ultimately disrupts normal sleep patterns, leading to poor-quality rest.
The severity and length of alcohol withdrawal insomnia vary, with some individuals experiencing prolonged withdrawal symptoms that can last for weeks or even months. Acute alcohol withdrawal symptoms typically last about 1-2 weeks, but latent withdrawal symptoms can persist for 8 weeks or more, especially in long-term heavy drinkers.
Managing alcohol withdrawal insomnia requires a comprehensive approach. Relaxation and mindfulness techniques, such as meditation, breathwork, and progressive muscle relaxation, can help calm the mind and body before bed. Building healthy habits, such as regular exercise, a well-balanced diet, and surrounding oneself with a positive social circle, can also improve sleep quality. Additionally, seeking professional help is important, as medical treatment professionals can provide medical detox and residential treatment to manage withdrawal symptoms and improve comfort during recovery.
