A podiatrist specializes in diagnosing and treating conditions of the foot, ankle, and lower leg. They attend podiatric medical school for four years and complete a residency. Common conditions treated include dermatological issues like fungal nail infections, orthopedic problems like plantar fasciitis and bunions, neurological disorders, and diabetes-related foot complications. Treatment options may include debridement, medications, orthotics, surgery, and wound care depending on the specific condition. Regular foot care can help prevent complications in patients with diabetes.
