There are several kinds of primary care doctors. Which specialty you search for depends primarily on your age:
Adults see internal medicine doctors (also called "internists").
Babies, children, and teenagers see pediatricians.
Seniors see geriatricians.
Anyone can see a family medicine doctor.
Primary care doctors see people for check-ups, physical exams, or routine bloodwork. They also help people with chronic illnesses manage their conditions.
Primary care doctors are very important. If you haven’t seen a doctor in a while, you will most likely start with a primary care doctor. If you have medical problems or concerns, your primary care doctor can diagnose you and refer you to the right specialist for further consultation.
