Family Medicine doctors use science and their clinical training to diagnose, treat, and advocate for patients of all ages and genders. A family medicine doctor, also known as a family practitioner, is a pediatrician and an internist combined into one job. Family practitioners care for all patients from newborns to seniors. They need to train for three years beyond medical school to become a family practitioner. Trainees are required to be able to provide acute, chronic, and wellness care for a large panel of different patients. To be a family practitioner, you will complete training in areas such as inpatient hospital care, adult critical care, emergency child care, obstetrics & gynecology, surgery, geriatric care, and musculoskeletal medicine. Because of all this training, family medicine doctors gain a broader spectrum of training than internists. This range of information can be useful in geographical areas where subspecialties may not be readily available. These doctors are known to serve rural and underserved populations.
