People go to medical school if they want to become a doctor. If you are interested in medicine, but do not want to become a doctor, then you would not go to medical school.
Before going to medical school, you first have to obtain a 4 year bachelor's degree (where you took at least biology, physics, and chemistry). In medical school, there is a preclinical and a clinical component to the study. Preclinical study includes core subjects such as anatomy, biochemistry, physiology, pharmacology, histology, pathology, and neurosciences.
The clinical component takes place often in a teaching hospital, and you observe and take part in the care of patients through rotations in internal medicine, surgery, pediatrics, family medicine, obstetrics/gynecology, neurology, and psychiatry. These are in essence your options, and you choose from among these specialties. After medical school, your residency and perhaps your fellowship will be in your specialty.
To sum up, if you go to medical school, you're going to become a doctor. However, you will choose what type of doctor to become based on the specialties listed above.
When you are actually in medical school, you probably don't have any time to hold a job. You spend some time shadowing doctors, but most of the focus is on your studies. Once you are done with your classes, you then go into residency, as Emma explains above. During your residency, you decide what type of medicine you want to practice. When you finish your residency, which can range in number of years, you then become a full-fledged, able-to-practice doctor. You already technically are a doctor after you finish school, but need to practice before going out on your own. There is also the opportunity to skip residency and go into consulting or other business professions where the MD title earns you extra income. Here's a Wikipedia article with more information on the different specialties and what they do: http://en.wikipedia.org/wiki/Specialty_%28medicine%29
There are lots of specialties, otherwise I would have just put them in here myself. It's a little beyond my ability to list them all!</body></html>
Types of physician
There are so many types of physicians. Broadly there are family practice doctors, internal medicine and its subspecialties, and surgery with its subspecialties. There are also physicians that don't fit in these such as psychiatry, radiology, pathology , physical medicine/rehabilitation.
There are a lot of long hours studying in the library followed by long hours in the hospital, but it is a fulfilling career. There are so many opportunities after medical school... different specialties appeal to different individuals. Or you can follow a nonclinical route in research or even hospital administration.
