Nail Fungal Infection

Fungal infection of the toenails (also called onychomycosis) occurs when a fungus infects the tissue underneath the toenail. The result is discoloration of the nail. Often the nail becomes thickened and raised. It commonly involves several nails simultaneously. It often occurs in people with persistent moisture in their feet, such as with footwear that does not allow air circulation or in those who perspire excessively in their feet.


The diagnosis of fungal infection of a toenail can be made based on the appearance of the toe. In some cases a sample may be obtained, to look for fungus under a microscope or to grow and identify the fungus in a laboratory.


The treatment for fungal nail infections usually involves an antifungal medication. Oral medications are generally required to treat the fungus while new nail grows in. The medication needs to be taken for several weeks to months while a new, healthy nail grows in. Routine labwork is required on a monthly basis while taking the medication.  Antifungal medications applied to the surface of the nail are not usually effective. In other cases, the infected nail is removed.
