Alcohol Withdrawal Syndrome: Symptoms, Causes, Diagnosis & Treatment

Causes of Alcohol Withdrawal Syndrome

AWS occurs due to prolonged and excessive alcohol consumption, which alters the brain's neurotransmitter balance. Alcohol suppresses the central nervous system, and when consumption stops abruptly, the body struggles to readjust, leading to withdrawal symptoms.

Risk Factors

• Heavy and prolonged alcohol use

• Previous history of withdrawal episodes

• Underlying mental health conditions

• Poor nutrition and overall health

• Concurrent substance use disorders

Symptoms of Alcohol Withdrawal Syndrome

AWS symptoms typically appear within 6-24 hours after the last drink and can last up to a week. The severity depends on factors like alcohol dependence and overall health.

Mild Symptoms (6-12 hours after last drink)

• Anxiety and restlessness

• Nausea and vomiting

• Tremors (shaking hands)

• Headache

• Insomnia

• Increased heart rate and sweating

Moderate Symptoms (12-48 hours after last drink)

• Hallucinations (auditory, visual, or tactile)

• High blood pressure

• Irritability and mood swings

• Confusion and disorientation

Severe Symptoms – Delirium Tremens (DTs) (48-72 hours after last drink)

• Severe agitation

• Seizures

• High fever

• Profound confusion

• Rapid heart rate

• Hallucinations and delusions

Diagnosis of Alcohol Withdrawal Syndrome

A healthcare provider diagnoses AWS based on medical history, reported symptoms, and clinical assessment. The Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) is often used to determine severity.

Common Diagnostic Criteria

• History of prolonged alcohol use

• Symptoms appearing after alcohol cessation

• No other medical explanation for symptoms

Treatment Options for Alcohol Withdrawal Syndrome

Treatment varies depending on severity. Mild cases can be managed at home, while severe cases require hospitalization.

Home-Based Treatment (For Mild Cases)

• Hydration and proper nutrition

• Over-the-counter medications for headaches and nausea

• Support from family or a sponsor

Medical Treatment (For Moderate to Severe Cases)

• Benzodiazepines (e.g., diazepam, lorazepam) to reduce withdrawal symptoms and prevent seizures

• IV Fluids & Electrolytes to restore balance

• Beta-Blockers to control heart rate and blood pressure

• Antipsychotic Medications for hallucinations and severe agitation

• Thiamine (Vitamin B1) to prevent Wernicke-Korsakoff syndrome

Long-Term Management & Prevention

• Detox Programs: Supervised withdrawal in a medical facility

• Behavioral Therapy: Cognitive-behavioral therapy (CBT) and motivational interviewing

• Support Groups: Alcoholics Anonymous (AA) and peer support groups

• Medication-Assisted Treatment (MAT): Medications like naltrexone or acamprosate to reduce cravings

Complications of Alcohol Withdrawal Syndrome

• Seizures: Can be life-threatening if untreated

• Delirium Tremens (DTs): High mortality rate without medical intervention

• Chronic Cognitive Impairment: Persistent memory and cognitive issues
