Geriatrics

Geriatrics is a medical discipline dedicated to the comprehensive care of older adults, focusing on maintaining function, independence, and quality of life. Unlike organ-specific specialties, geriatrics addresses the complex interactions between multiple chronic conditions, aging physiology, functional decline, and social factors. Geriatric care emphasizes holistic assessment, including mobility, cognition, nutrition, medication burden, and psychosocial well-being. Aging alters pharmacokinetics, immune responses, and stress tolerance, requiring age-specific clinical decision-making. Geriatrics prioritizes prevention of frailty, falls, disability, and hospital-associated decline. The field integrates principles of aging biology with patient-centered care, recognizing heterogeneity in aging trajectories. Geriatrics plays a critical role in managing multimorbidity, coordinating care, and aligning medical interventions with patient goals. Understanding geriatrics is essential for translating aging science into practical strategies that preserve autonomy and resilience in later life.
