A doctor is someone who practices medicine to treat illnesses and injuries.
Doctors go to medical school to be trained. They typically hold a college degree in medicine. Doctors once made house calls to treat patients at home, but now mostly see patients in their offices or in hospitals. Doctors may also work for schools, companies, sports teams, or the military. Doctors are often assisted by nurses or other staff.
Some doctors specialize in a certain kind of medicine. These doctors are called specialists. They may only treat injuries to a certain part of the body, or only treat patients who have certain diseases. For example, there are doctors who specialize in diseases of the stomach or intestines. Other doctors are â€œgeneral practitionersâ€ or â€œfamily practitionersâ€. This means that they do a little bit of everything. They try to deal with as much of a patientâ€™s health problems as they can without sending them to a specialist. A doctor who performs surgery is called a surgeon.
Other kinds of doctors specialize in treating eyes. They are called eye doctors, or optometrists. They give people glasses or contact lenses. Doctors who specialize in treating feet are called podiatrists. They often give people medicine for feet, such as creams. These doctors are usually found working in their own offices, as opposed to other offices.
