Alcohol Withdrawal

Alcohol withdrawal syndrome is characterized by onset of symptoms that occurs in individuals who suddenly stop drinking alcohol. It essentially occurs in the alcohol drinking population who all of a sudden either decreases their alcohol intake or stops its consumption.

The disease originates from the following process: Poison.

Presentation

Symptoms of alcohol withdrawal usually develop within 8 hours after the last drink. However, in many instances, symptoms may occur after many days. Symptoms include depression, anxiety, nervousness, mood swings, nightmares, irritability, fatigue, headache, enlarged pupils, pallor, sweating and rapid heart rate. In more severe forms of alcohol withdrawal, delirium tremens may set in. Individuals experience fever, hallucinations, seizures, confusion and agitation [7]. Symptoms continue for several weeks and peak within 24 to 72 hours after the onset of preliminary signs [8].

Workup

A preliminary physical exam to evaluate the signs and symptoms of the condition would be carried out. Physical examination would show signs of tremors, fever, dehydration, abnormal movements of eye and arrhythmia.

In addition to physical examination, blood and urine tests would also be carried out to assess the amount of alcohol in body. A toxicology screen is also required to confirm the diagnosis.

Treatment

The type of treatment involved depends on the severity of the symptoms experienced. Some patients with mild to moderate symptoms can be treated at home; while others may require hospitalization to avoid onset of unnecessary complications such as delirium. Treatment of alcohol withdrawal is aimed at relieving symptoms, preventing onset of complications and achieving permanent abstinence from alcohol [9].

Outpatient treatment: In this, the individual gets treated for alcohol withdrawal symptoms, through medications and regular visits to the doctor. It is required that the patient is constantly monitored by a caregiver to look for adverse symptoms of the condition. The individuals are put on sedatives to ease the symptoms and are regularly screened through blood tests. In addition, they are also screened for other medical problems which can worsen the existing condition.

Inpatient treatment: Individuals experiencing severe symptoms may require a hospital stay to be monitored closely for onset of complications. All the vital parameters of the individual such as blood pressure, heart rate, body temperature, and blood levels of chemicals will be tested. In case of dehydration, the individual will be given IV fluids to correct the condition. Administration of sedatives such as benzodiazepines will be employed, until the withdrawal process is completed. Patients are also given nutritional supplements to correct nutritional deficiencies that have occurred due to long term alcohol abuse [10].

Prognosis

The prognosis of the condition is usually favorable when individuals are given prompt treatment. Individuals however, tend to suffer from insomnia, fatigue and irritability for several months. It is necessary that alcohol withdrawal symptoms are treated with appropriate medications and therapies. This is so because, if the patients begin experiencing delirium, it can turn life threatening [6].

Etiology

Sudden cessation of alcohol consumption or significantly reducing the alcohol intake can cause development of alcohol withdrawal symptoms. It is more common in individuals who drink regularly and are unable to gradually decrease the consumption. Individuals who are suffering from certain underlying disease conditions are also at risk of developing alcohol withdrawal symptoms when they suddenly stop its consumption. In addition to adults, even teenagers and children who drink excessive alcohol are also susceptible to develop alcohol withdrawal symptoms [2].

Epidemiology

Alcohol withdrawal is a common phenomenon. It has been estimated that about 500,000 episodes of alcohol withdrawal symptoms occur each year in the US. About 5% of these individuals are known to fall prey to delirium tremens. The symptoms are so severe that they require pharmacologic intervention [3]. It has also been reported that about 50% patients who drink alcohol develop clinically relevant symptoms. In addition, less than 1 in 20 individuals who drink alcohol are also at risk of developing grand mal seizures or delirium tremens. Another statistical report revealed that mortality rate was as high as 20% in drinker’s population who suffered from delirium tremens [4].

Pathophysiology

Drinking excessive alcohol on regular basis is known to gradually excite the nervous system. Over time when such a phenomenon continues, the body is unable to tolerate sudden cessation of alcohol. This means, the nervous system cannot easily adapt to sudden change in the alcohol consumption pattern causing various symptoms such as delirium, insomnia and anxiety to name a few [5].

Prevention

Individuals are advised to gradually and slowly decrease their dependence of alcohol. This can be achieved by making conscious efforts by decreasing alcohol intake steadily. Such a practice will help prevent symptoms of alcohol withdrawal from setting in. It is also advised that individuals who wish to completely quit alcohol should seek medical advice to ensure a healthy withdrawal.

Summary

Alcoholism is a common occurrence with an estimated 140 million people throughout the world which suffer from alcohol dependence. The practice of drinking alcohol is certainly not good for the human system and has debilitating effects on the nervous system and other body organs. Alcohol withdrawal can produce various physical and emotional symptoms, which if not managed appropriately can get life threatening. Such a kind of phenomenon is common in adults; however teenagers and children can also often fall prey to it [1].

Patient Information

Definition

Alcohol withdrawal is a condition wherein individuals experience a group of symptoms when they suddenly stop drinking alcohol. An estimated 15.2 million Americans are alcoholic. Of these 1.2 million of hospital admissions occur due to alcohol withdrawal. Symptoms of alcohol withdrawal should be promptly treated to avoid onset of complications.

Cause

Sudden cessation of alcohol or significant decrease in alcohol intake causes alcohol withdrawal symptoms to set in. Individuals with certain underlying disease conditions experience more severe forms of alcohol withdrawal symptoms as compared to the normal population.

Symptoms

Symptoms of alcohol withdrawal include headache, anxiety, nervousness, mood swings, depression, irritability, enlarged pupil, sweating, arrhythmia, loss of appetite and insomnia. In more severe cases, individuals experience fever, agitation, seizures and severe confusion which occur due to development of delirium tremens.

Diagnosis

Diagnosis of alcohol withdrawal symptoms is done through a preliminary physical examination to categorize the signs and symptoms. In addition, blood and urine tests are also carried out to assess the level of alcohol in the system.

Treatment

Mild form of the condition is treated through medications and patients are allowed to stay at home. In severe cases, hospitalization is also required to manage the symptoms of the conditions. Medications such as benzodiazepines are recommended for patients with alcohol withdrawal.
