What is alcohol dependence?
Alcohol dependence, also known as alcohol use disorder (AUD), is a medical condition characterized by a pattern of problematic drinking. It involves:
- Craving or strong urge to drink
- Loss of control over how much is consumed
- Tolerance (needing more to achieve the same effect)
- Physical withdrawal symptoms when drinking stops
- Continued use despite negative consequences
In 2021, an estimated 28.8 million adults (11.2% of those 18 and older) and 753,000 adolescents (2.9% of ages 12–17) in the US met criteria for AUD.
Causes
Alcohol dependence arises from a combination of factors:
- Genetics and family history of alcohol problems
- Environmental influences such as peer pressure, cultural norms, and early exposure
- Psychological factors including stress, trauma, and co-occurring mental health disorders
- Neurobiological changes in dopamine, serotonin, and GABA pathways
- Developmental timing, with earlier initiation increasing later risk
Common symptoms and signs
- Strong cravings for alcohol
- Inability to limit drinking once started
- Blackouts or memory lapses
- Withdrawal symptoms such as tremors, sweating, or nausea
- Drinking to relieve or avoid withdrawal
- Neglecting responsibilities at work, school, or home
- Continued use despite health, legal, or relationship problems
Treatment options
Effective treatment typically combines several approaches:
- Medical detoxification under supervision to manage withdrawal
- Medication-assisted treatment (naltrexone, acamprosate, disulfiram)
- Behavioral therapies (cognitive-behavioral therapy, motivational enhancement)
- Support groups (Alcoholics Anonymous, SMART Recovery)
- Counseling and psychotherapy for co-occurring mental health issues
- Family therapy and involvement of loved ones
- Lifestyle changes such as stress management, exercise, and avoiding triggers
- Continuing care and relapse prevention planning
Long-term effects on health and well-being
Chronic alcohol dependence can lead to serious complications:
- Liver disease (fatty liver, hepatitis, cirrhosis)
- Cardiovascular problems (high blood pressure, heart disease, stroke)
- Gastrointestinal disorders (pancreatitis, ulcers, bleeding)
- Neurological damage (cognitive impairment, neuropathy, Wernicke-Korsakoff syndrome)
- Increased cancer risk (liver, esophageal, breast, mouth)
- Mental health issues (depression, anxiety, increased suicide risk)
- Social and economic hardships (relationship conflict, job loss, legal troubles)
- Higher risk of accidents and injuries
