If you want to help sick or injured people and love science, you may enjoy a career as a doctor. There are many types of doctors, but they all aim to get and keep patients healthy.

A doctor's first job is to find what is wrong with patients. They interview patients to find out their complaints and conduct physical exams. Doctors diagnose patients by their symptoms, medical histories, and tests. They may need to take x-rays, do blood tests, or perform biopsies.

After making a diagnosis, the doctor prescribes a treatment plan. Treatments can vary depending on the medical problem. Doctors may need to treat wounds and prescribe or give medication to their patients. Sometimes they have to schedule surgery. Doctors also recommend therapies and give their patients advice about exercise and diet.

Doctors often work with other health care workers when they treat patients. They may consult with nurses, lab technicians, or physiotherapists on a daily basis.

There is more to a doctor's day than seeing patients. Doctors who run their own practices have many business-related duties. Those who work in hospitals are often on boards. They help develop new programs and policies.

Doctors may also teach and work on research projects. Some work with the public to promote healthy living.

Surgeons, pediatricians, and psychiatrists are just a few types of doctors.
