Fungal Friends and Foes

Onychomycosis is primarily caused by dermatophytes, with Trichophyton rubrum being the most common offender. These fungi are particularly prevalent in warm and moist environments, making feet a perfect target. Besides dermatophytes, yeasts and molds like Candida species and nondermatophyte molds also contribute to nail infections.

Factors That Increase Risk

Certain conditions can make you more susceptible to onychomycosis. These include existing skin conditions like athlete's foot, diabetes, or a weakened immune system. Other risk factors include nail injuries, wearing tight shoes, and having damp feet for prolonged periods.
