Liver Disease: Prevalence, Risk Factors, and Causes

Liver disease is the 11th leading U.S. cause of death (~48,000 deaths in 2019). More common in men; risk increases with age.

Common Types

  • Nonalcoholic fatty liver disease (NAFLD): Fat buildup; affects ~25% of U.S. adults.
  • Alcoholic liver disease (ALD): Excessive alcohol consumption.
  • Hepatitis B & C: Viral infections causing liver damage.
  • Cirrhosis: Late-stage scarring leading to liver failure.

Early detection improves treatability. See a doctor for symptoms: fatigue, nausea, vomiting, abdominal pain, jaundice (yellow skin/eyes).
