There are many types of physicians, each with his or her area of expertise.

General practitioners. These doctors treat a wide variety of health problems–they do not specialize in one area of medicine.

Family practitioners. These doctors provide care for all ages. They are a popular choice if you would like one doctor to become familiar with the health history of your entire family.

Internists. Internists provide care for adults only, covering a wide spectrum of disorders. Many medical specialties require education as an Internist before further specializing in a branch of medicine.

Specialists. Specialists are Internists with additional training in a certain area. For example, a cardiologist is specially trained to treat heart problems.

General practitioners, family practitioners and internists provide what is called primary care. That is, they treat diseases and conditions but also advise you on how to prevent health problems. While some specialists also provide primary care, many prefer not to practice general medicine.
