Aging changes both the presentation of disease and the goals of care. Geriatrics is the branch of medicine focused on the health and care of older adults, emphasizing function, multiple chronic conditions, and quality of life.

Geriatricians assess mobility, cognition, medications, nutrition, and social support in addition to individual diseases. They manage polypharmacy, delirium, falls, and frailty. Care often involves families and interdisciplinary teams. Decisions weigh benefits of treatment against burdens in the context of remaining life expectancy and patient values.

Not every older person needs a geriatrician, yet geriatric principles improve care across specialties. Preventing hospital-acquired disability and supporting safe discharge are practical priorities. As populations age, demand for geriatric expertise continues to grow.
