Another MD checking in.
Is your daughter in high school or college? While it is very important to not hate science, there are often misconceptions that one has to be a biology major in order to attend medical school. There is usually a general set of pre-requisites in order to apply to medical school (generally 1 year of biology, 1 year of general chemistry, 1 year of organic chemistry, 1 year of physics, and generally an English class and a semester of math) but otherwise one can major in any area. I was a biology and English major – I did the biology major because I loved the field; however, over the long term, I think the English major may have been just as good of a preparation in terms of critical thinking and writing for medicine. In my medical school class, there were plenty of biology or chemistry majors but there were also engineers, former lawyers, and a variety of different majors in the humanities or social sciences.
Regarding specialties, there were a few people in my class who came in saying they knew they would go into pediatrics or surgery, etc., but the majority either did not know or ended up doing something very different from what they thought they wanted to do before entering medical school.
The majority of US medical schools have students spend the majority of the first two years in classes such as gross anatomy, microbiology, biochemistry, and pathology.
The third and fourth years are the clinical years. There is some variation from school to school but the majority of schools will have all students rotate through a core group of rotations (internal medicine, pediatrics, ob-gyn, surgery, psychiatry, etc.). The amount of time spent on each rotation may vary from school to school; for example, at my school, we spent three months each in surgery and internal medicine while the remainder of our rotations (pediatrics, family medicine, psychiatry, ob-gyn). During the fourth year at the school I attended, there were a couple of required rotations, a few selectives (i.e., had to take 3 out of a list of about 12 different rotations), and the remainder were electives.
I was one of the students who came in “knowing” what specialty I wanted to do and actually ended up doing it. However during the third year, I went through considering several different areas because I enjoyed the different rotations so much.
Another thing to consider is that within a particular specialty there is going to be a whole lot of different options for practice (100% inpatient vs. 100% outpatient vs. mix ; academic medicine vs. private practice, etc.) even if one does not further subspecialize (i.e., complete a fellowship in a particular area of the primary specialty such as cardiology).
Some specialties may offer more flexibility than others in term of life-work balance. I think I currently have the perfect job in my subspecialty (although a lot of my colleagues HATE my subspecialty) – good reimbursement, some academics, and generally good life-work balance. However, my non-physician friends would likely consider my work schedule to be “too much” when it comes to call duties. There is also a bit of an emotional burden and learning how to prevent burnout is critical.
Anyway, sorry for the long rambling post.
