Internal Medicine contains many subspecialties that include Cardiologists, Endocrinologists, Nephrologists, Pulmonologists, and Geriatrics.  Geriatric medicine focuses on the health of elderly people treating diseases and disabilities in older adults including referrals to home care services and assisted living facilities.

Conditions that most commonly affect the elderly can include dementia, delirium, immobility, instability, incontinence, impaired intellect/memory, impaired vision, hearing loss, and injury as a result of falls.

Internists can work in consultation with other medical specialists through referrals and combined treatment alongside Emergency Medicine and Critical Care doctors, Family Doctors / General Practitioners, and Nurse Practitioners. Internists carry out research and can practice in a number of different environments including hospitals, private offices, intensive care clinics, and nursing homes.
