A podiatrist is a specialist who provides medical evaluation and treatment of foot and ankle problems. In addition to undergraduate medical school training, podiatrists attend podiatric medical school for a doctorate degree in podiatry (Doctor of Podiatric Medicine or DPM). Podiatrists take the same courses and hospital rotations during their training as general medical doctors, often side-by-side with them. However, podiatrists are required to take additional courses and hospital rotation that are specific to their area of specialization. Like all other doctors, podiatrists are required to take state and national licensing exams, as well as be licensed by the state in which they practice. According to the American Podiatric Medical Association, there are more than 18,000 practicing podiatrists in the United States. Podiatrists are in demand more than ever today because of a rapidly aging and active population. In addition, according to the association, foot disorders are among the most widespread and neglected health problems affecting people in this country.
