In choosing an internal medicine subspecialty, there are several things to consider. The type of work you want to do and the training you need to become a physician will all play a role in the selection process. If you are considering a career in general internal practice, you can choose to specialize in a specific field. But it is not necessary to choose a subspecialty from the start.
Women in medical school are becoming more prevalent, but still under-represented in internal medicine fellowships. Researchers from the Journal of the American Medical Association analyzed data from 1991 to 2016 to examine the gender-ratio of internal medicine subspecialties. If you are thinking about pursuing a specialty, you can use FREIDA to find out about the number of fellowship programs in your area. Some of these programs are accredited by the ACGME, and are ranked by their experience and training.
