Abstract

Metabolic disorders such as diabetes mellitus are frequently associated with serious hepatic and renal complications 
that contribute significantly to morbidity and mortality. The underlying mechanisms involve complex interactions 
among hyperglycemia, dyslipidemia, inflammation, and oxidative stress. Oxidative stress, characterized by an 
imbalance between reactive oxygen species (ROS) production and antioxidant defenses, plays a central role in the 
pathogenesis of diabetes-induced liver dysfunction and diabetic nephropathy. Excessive ROS disrupts cellular 
macromolecules, alters mitochondrial integrity, and activates pro-inflammatory and fibrotic signaling cascades in 
both hepatic and renal tissues. This review explores the molecular and biochemical basis of oxidative stress in the 
progression of hepatic and renal complications in diabetes, emphasizing the interplay between metabolic 
disturbances, redox imbalance, and cellular injury. It further discusses potential therapeutic strategies targeting 
oxidative stress, including antioxidant supplementation, Nrf2 activation, mitochondrial protection, and the use of 
bioactive phytochemicals. Understanding these mechanisms provides a foundation for developing targeted 
interventions to prevent or mitigate organ damage in metabolic diseases.
