What is Toenail Fungus (Onychomycosis)?

Toenail fungus, or Onychomycosis, is a common infection that causes nails to become thick, discolored (yellow, brown, or white), brittle, and sometimes crumbly. The fungus lives in and under the nail plate and rarely resolves without professional intervention.

Causes and Risk Factors

Fungus thrives in specific conditions, and certain factors increase susceptibility:

  • Environment: Public places like swimming pools, locker rooms, and showers are common sources of infection.
  • Footwear: Tight, non-breathable shoes create a dark, moist environment where fungus can thrive.
  • Trauma: Repetitive minor trauma to the nail can create openings for the fungus to enter.
  • Health: Underlying conditions like diabetes, poor circulation, and a weakened immune system increase risk.

Symptoms of Fungal Infection

The visual changes in the nail are typically the primary symptom:

  • Discoloration: Yellow, white, or brown streaks or patches on the nail.
  • Thickening: The nail plate becomes dense and difficult to trim, a service available at the Overlea Office.
  • Brittleness/Crumbling: The nail edge becomes fragile and breaks easily.
  • Odor: A slightly foul smell may emanate from the infected nail.

Professional Treatment Strategies

Over-the-counter products often fail because they cannot penetrate the nail plate. We offer professional-grade solutions at the Foot Centers of Maryland Glen Burnie Office:

  • Professional Debridement: Painlessly thinning and reducing the thickness of the fungal nail to allow topical medications to penetrate more effectively.
  • Topical Medications: Prescribing powerful topical lacquer or solutions.
  • Oral Medications: For severe or widespread infections, prescription oral antifungals are often necessary.
  • Prevention: Guidance on using antifungal sprays for shoes and keeping feet clean and dry to prevent reinfection.
