Nonalcoholic fatty liver disease (NAFLD) arises from insulin resistance, leading to fat buildup in the liver. This review explores the key factors driving NAFLD development and progression to non-alcoholic steatohepatitis (NASH).

Area of Science:

  • Hepatology
  • Metabolic Disorders
  • Liver Pathogenesis

Background:

  • Nonalcoholic fatty liver disease (NAFLD) is a prevalent liver condition.
  • Insulin resistance is a key factor in NAFLD pathogenesis, particularly with co-occurring metabolic syndrome.
  • Insulin resistance disrupts hepatic glucose and lipid metabolism, leading to fat accumulation.

Purpose of the Study:

  • To review the multifaceted pathogenesis of NAFLD.
  • To elucidate the role of insulin resistance in NAFLD development.
  • To discuss factors contributing to the progression from NAFLD to non-alcoholic steatohepatitis (NASH).

Main Methods:

  • Literature review of NAFLD pathogenesis.
  • Analysis of the role of insulin resistance in metabolic dysregulation.

  • Examination of inflammatory pathways in NAFLD progression.

    • Main Results:

    • Insulin resistance is central to NAFLD development, impairing liver function.
    • Hepatic fat accumulation occurs when regulatory mechanisms are overwhelmed by metabolic insults.
    • Adipocytokines and free fatty acid toxicity can trigger inflammation, leading to NASH.

    Conclusions:

    • NAFLD development is intrinsically linked to insulin resistance.
    • The progression to NASH involves inflammatory responses triggered by cellular stress.
    • Understanding these pathways is crucial for managing NAFLD and NASH.
