What Does a Podiatrist Do and When Should You See One?

Podiatry is a specialized branch of medical practice dedicated to the study, diagnosis, and treatment of disorders affecting the foot, ankle, and related structures of the lower leg. This focus encompasses a wide range of conditions, from minor skin issues to complex surgical procedures and chronic disease management. Podiatrists address problems in this intricate anatomical region to maintain patient mobility and overall quality of life.

Conditions Requiring Podiatric Care

Podiatrists frequently address common, localized ailments affecting daily comfort and movement. These include painful soft tissue conditions like plantar fasciitis, which is inflammation of the thick band of tissue across the bottom of the foot, often causing sharp heel pain in the morning. They also treat structural deformities such as bunions, which are bony protrusions at the base of the big toe causing swelling and joint misalignment.

Routine care involves managing skin and nail issues like ingrown toenails, where the nail edge grows into the surrounding skin, and fungal infections, such as athlete’s foot. Podiatrists also treat pressure-related problems like corns and calluses, which are areas of hardened skin painful due to friction or improper foot mechanics. They diagnose and manage minor sports injuries, including ankle sprains, strains, and stress fractures resulting from repetitive activity or sudden trauma.

The Role of Podiatry in Systemic Health

The feet often act as early indicators of systemic diseases, making the podiatrist a collaborator in managing chronic conditions. A major focus is diabetic foot care, as high blood sugar levels can lead to two main complications: peripheral neuropathy and peripheral vascular disease. Neuropathy involves nerve damage, causing numbness or loss of sensation, meaning a person might not feel a minor cut or blister, allowing it to progress unnoticed into a severe ulcer.

Peripheral vascular disease restricts blood flow to the lower extremities, hindering the body’s ability to heal wounds and fight infection. Podiatrists perform routine, comprehensive foot exams for diabetic patients, assessing pulses, sensation, and skin integrity to prevent ulcers and subsequent amputations. They also manage foot complications arising from inflammatory conditions like rheumatoid and osteoarthritis, which cause significant joint swelling and structural changes. These changes can alter gait and foot shape, requiring specialized care like custom orthotics to improve stability and reduce joint damage.

Education and Professional Credentials

A podiatrist undergoes a specialized educational path to become an expert in lower extremity health. The journey begins with an undergraduate degree, followed by four years of specialized podiatric medical school. Graduates earn the Doctor of Podiatric Medicine (DPM) degree, which is focused specifically on the foot and ankle.

After medical school, the DPM must complete a postgraduate residency program, which typically lasts three to four years. This hospital-based training provides hands-on experience in various medical and surgical settings, including rotations in internal medicine, infectious disease, and surgery. Many podiatrists pursue board certification through recognized bodies, signifying a high level of competency in their field, such as foot and ankle surgery or podiatric medicine.

When to Consult a Podiatrist

Seeking specialized care is advisable for any persistent pain or discomfort in the feet or ankles that does not resolve with self-care. This includes heel pain that is worst in the morning, a common sign of plantar fasciitis, or any new difficulty with walking or maintaining balance. Numbness, tingling, or a burning sensation in the feet should prompt a visit, as these can be signs of nerve damage related to conditions like diabetes.

Any change in the appearance of the skin or nails, such as sudden discoloration, swelling, or the development of thick, brittle toenails, warrants a consultation. A sore, blister, or cut on the foot that is slow to heal, particularly for individuals with poor circulation or chronic diseases, requires immediate professional attention to prevent infection. A general practitioner may also recommend a referral if they suspect an underlying structural issue or a systemic disease manifesting in the lower extremities.
