Allostasis, a framework that focuses on physiological adaptations to stress and the maintenance of stability through change, provides a valuable perspective for understanding these diseases. This review summarizes how the allostasis framework defines the cumulative physiological burden—known as allostatic load—imposed by chronic stressors such as persistent psychosocial pressure, drug abuse, and chronic infections. It also explores how adaptive physiological shifts, or changes in allostatic state, contribute to disorders, particularly drug addiction, immune diseases, and cancer. We then review recent studies that uncover stress adaptation mechanisms using cutting-edge technologies, such as multi-omics approaches, induced pluripotent stem cells (iPSCs), and organoid technology. This integrative approach, combining advanced technologies with the allostasis framework, can deepen our understanding of complex disease pathogenesis and inform the development of more effective diagnostic and therapeutic strategies.
