A geriatrician is a medical doctor who specializes in the care of older adults, typically those aged 65 and above. They are trained to address the complex medical, emotional, and social needs of aging patients, often managing multiple chronic conditions such as arthritis, dementia, diabetes, and heart disease. Geriatricians focus on improving quality of life, maintaining independence, and preventing or managing age-related health issues. They work closely with families and other healthcare providers to create personalized care plans that consider the patient’s overall well-being, functional status, and goals of care.
