What is nail Fungus?

Nail fungus (also called onychomycosis) is made up of very small organisms that can infect fingernails and toenails. These organisms are called dermatophytes. Fungi are parasitic plant organisms, such as molds and mildew. These parasitic organisms lack chlorophyll and therefore do not require sunlight for growth. Nail fungus is very common. More than 35 million people in the US have it under their nails. Once the nail fungus moves in under the nail, it is difficult to reach and stop. The nail provides a safe place for the fungus and protects it while it grows. This is why basic prevention is so important.
Nail fungus can sometimes spread from one person to another. These organisms can live where the air is often moist and people's feet are bare. Common places that fungus can spread include: shower stalls, bathrooms, or locker rooms. It can also be passed along when you share a nail file or clippers with someone who has a nail fungus infection. Nail fungus may also spread from one of your nails to others.

What causes nail fungus

The fungal organisms that cause nail infections are present almost everywhere. Once they get under the nail bed they can be difficult to cure. Anything that damages a nail can make it easier for the fungus to move in. Examples include an injury to the nail such as getting a finger stuck in a door, or tight shoes that pinch the toes. A weakened immune system can also make it easier for a fungal infection to start. Many medical professionals believe that having a strong immune system is essential for preventing fungus infections.

You need to be very careful when trimming nails. Do not cut them too short, as this can result in small openings that allow fungus to get under the nail. Nail Biting can also contribute to this condition. Nail biting can leave the nail without its natural protection against infections.

The fungi that cause nail infections are present in many public areas such as pools and locker rooms. Be sure to wear slippers or some sort of barrier on your feet in such settings.

Always keep your feet as dry as possible, and change socks frequently. This is especially true if you have a job that causes your hands or feet to be damp for extended periods. Fingernail polish can also contribute to nail fungus, since it does not allow the nail to breathe. Most people will not develop a fungal nail infection simply from wearing fingernail polish. However if an infection is present, it may be wise to stop using such products.
