Fungal nail infection

What is it ?


Onychomycosis is a fungal infection of the nail plate, nail bed, or both.

  • Walking barefoot in damp public areas, such as swimming pools, gyms and shower rooms

  • Having a minor skin or nail injury

  • Having a skin condition that affects the nails, such as psoriasis

  • Having diabetes, blood flow problems or a weakened immune system


Signs and Symptoms


  • Thickened nails

  • Discolored nail plate

  • Crumbly debris under the nail plate

  • Separation of the nail from the nail bed

  • Misshapen nail

  • Malodorous


Treatment


  • Mechanical debridement of the affected nails to reduce its thickness, to allow penetration of topical agents

  • Use topical antifungal treatment as directed for a minimum of 6 months

  • Maintain personal hygiene

  • Laser treatment

  • Oral antifungals may be required if the diagnosis of fungal infection is confirmed with fungal pathology testing
