Many people are familiar with skin diseases and infections caused by bacteria and viruses, but fewer realize that fungi are also a common cause of skin infections.

One of the most frequent areas for fungal infections to develop is the feet. These infections can affect the skin’s surface and even the nails. The two most common fungal infections are athlete’s foot and toenail fungus, both of which are chronic conditions typically seen in adults.

Causes of Foot Fungus

Fungi thrive in dark, moist environments, making the feet, especially the areas between the toes, an ideal breeding ground. Fungal infections are often contracted in public spaces such as locker rooms, swimming pools, and communal showers. They can spread quickly from one person to another, especially among teammates or family members.

Certain individuals are more susceptible to developing foot fungus, including those with diabetes, an abnormal skin pH level, or a weakened immune system. Additionally, a previous injury to the nail bed can increase the likelihood of infection.

Symptoms of Foot Fungus

On the skin, common symptoms of a fungal infection include:

  • Burning sensation
  • Cracked or bleeding skin
  • Itching
  • Redness
  • Small blisters
  • Stinging

On the toenails, symptoms may include:

  • Yellowing or discoloration of the nails
  • Debris or buildup beneath the nails
  • Foul odor
  • Thickening of the nails
  • White spots or streaks on the nails

Treatment for Foot Fungus

Treating foot fungus can be challenging, but it starts with creating an environment that is less conducive to fungal growth. Your doctor may recommend the following:

  • Avoid cutting your toenails too short to prevent further injury.
  • Change your socks frequently throughout the day to keep feet dry.
  • Ensure your feet are thoroughly cleaned and dried at all times.
  • Wear breathable shoes to allow proper air circulation.
  • Use shower sandals in public areas to avoid contact with contaminated surfaces.

The next step in treatment is to address the fungal infection itself. Your doctor may prescribe antifungal creams or washes to apply directly to the affected area. In more severe cases, oral antifungal medications may be necessary for a multi-week course of treatment. In some instances, your doctor may need to remove part or all of the infected toenail to prevent the infection from recurring.

Above all, it’s crucial to follow through with treatment until all symptoms have completely disappeared to avoid reinfection.
