Athlete's foot is a common fungal infection that can cause itching, burning, and dry, scaly skin on the feet and toes. While it may seem like a minor issue, it can lead to more serious complications if left untreated, particularly in the elderly, those with diabetes, or people with weakened immune systems. Proper foot hygiene, antifungal treatments, and preventative measures are key to managing athlete's foot and avoiding potential problems like cellulitis.

Why it matters

Athlete's foot is often overlooked or undertreated, but it can serve as a gateway for dangerous infections, especially in high-risk populations. Raising awareness about the importance of addressing athlete's foot promptly can help prevent more serious health issues down the line.

The details

Athlete's foot, also known as tinea pedis, is a fungal infection that thrives in warm, moist environments like sweaty feet and damp socks and shoes. It can present as dry, scaly skin on the soles or between the toes, blisters, or pustules. The infection can spread easily to others and, if left untreated, can spread to other parts of the body. People with diabetes, peripheral vascular disease, or weakened immune systems face a higher risk of serious complications from athlete's foot, such as cellulitis, a potentially limb-threatening bacterial skin infection.

  • Athlete's foot becomes more common in warmer, humid climates, especially during the summer months.

What they’re saying

“Athlete's foot can be a portal of entry for some dangerous infections, particularly in the elderly and people with diabetes. So, it's important to realize that it is a problem.”

— Georgeanne Botek, Head of Podiatry

“Many times, athlete's foot is asymptomatic. But in the elderly or others at higher risk, we can see serious complications that can end up with multiple visits to the doctor, multiple prescription medications and impairment to your normal activity.”

— Georgeanne Botek, Head of Podiatry

What’s next

If athlete's foot doesn't improve with over-the-counter treatment or if you develop signs of a bacterial infection, call your healthcare provider. You might need stronger oral antifungal medications to treat the infection.

The takeaway

Athlete's foot is a common but often overlooked condition that can lead to serious complications, especially for those with underlying health issues. Practicing good foot hygiene, using antifungal treatments, and seeking medical attention if the infection persists or worsens are crucial steps to prevent more serious problems.
