Binge Drinking: Definition, Acute Dangers, and Long-Term Health Consequences

Binge drinking is a pattern of alcohol consumption that brings blood alcohol concentration (BAC) to 0.08% or higher—typically ≥5 drinks (male) or ≥4 drinks (female) in about 2 hours.

Acute Risks

• Alcohol poisoning (CNS depression → respiratory arrest, aspiration, hypothermia).
• Unintentional injuries: falls, drowning, burns, MVCs.
• Violence: assault, sexual assault, homicide, suicide.
• Risky sexual behavior: unprotected sex, STIs, unintended pregnancy.
• Blackouts (anterograde amnesia).

Chronic Consequences (Repeated Bingeing)

• Liver: Steatosis → steatohepatitis → fibrosis → cirrhosis.
• Cardiovascular: Hypertension, atrial fibrillation, cardiomyopathy, stroke.
• Neurologic: Cognitive decline, white matter loss, Wernicke-Korsakoff (thiamine deficiency).
• Cancer: Oral, pharyngeal, esophageal, liver, breast, colorectal.
• Pancreatitis (acute and chronic).
• Immune suppression → infections.

Epidemiology (US)

• 1 in 6 adults binge drinks ~4 times/month; 7 drinks per binge.
• Most common among 18–34, but >50% of total binge drinks consumed by those ≥35.
• Cost: $249 billion/year (lost productivity, healthcare, crime).

Screening & Intervention

• AUDIT-C (3 questions) or single question: "How many times in past year have you had ≥5/4 drinks in a day?"
• Brief motivational intervention (SBIRT) in primary care/ED.
• Treatment: naltrexone, acamprosate, disulfiram; CBT, mutual support (AA, SMART).
