Podiatry is a profession of Health Sciences that deals with the examination, diagnosis, and treatment of conditions and functions of the human foot and the biomechanical evaluation of walking of the lower limb. Because many diseases are often first manifested by symptoms in the feet, the Podiatrist is frequently called upon to point out a patient's possible affliction with other disorders, among them being diabetes, arthritis and circulatory problems. The Podiatrist is trained to classify wounds, treat them and most importantly diagnose the etiology - circulatory or biomechanical. The Podiatrist is also trained to recognize and correct congenital malformations of the foot in infants. With the increase in the number of people taking part in physical exercise, many Podiatrists are now in close practice with sports medicine, such as the fitting of foot supports, called orthotics, for athletes with different sport activities.
