Fungal toe nails or onychomycosis is an infection caused by a fungal species known as dermatophytes but can also be caused by some yeasts or moulds. It typically invades the the nail if it becomes broken or damaged but can penetrate under the nail if there is a surrounding fungal skin infection.

At least 20% of the population over the age of 60 have a fungal nail infectionHaving sweaty or constantly moist feetBeing involved with sports that often injure the nails such as running or basketball/netballWearing shoes with poor ventilation/ made out of synthetic materials
Treatment for fungal nails vary and it can be a slow process as nails can take as long as 12 months to grow from base to tip. If the fungal infection is superficial or it involves the distal portion of the nail (the nail portion that is furthest from the cuticle), topical treatments can be used. These need to be used until the unhealthy portion of the nail has grown out. Nail polish or artificial nails cannot be worn for the period of time whilst you are treating the infection with topical anti-fungals. If there is widespread nail involvement and/or the infection is close to the cuticle region then oral antibiotics are generally required.
