Information about Nail Fungus

It's estimated that more than 11% of all North Americans have some sort of nail fungus. Toenail fungus is the most common problem foot specialists treat, but fingernails can become infected as well.

Symptoms of nail fungus include a yellowish or brownish discoloration of the nails, thick or brittle nails, crumbling at the edges of the nails, and nails that break easily. Toenails are most often affected but fingernails can also get nail fungus. The big toe seems to be the most likely to be affected.

There are a number of steps you can take to help prevent nail fungus. It's mostly a matter of good hygiene.

Wear natural wool or cotton socks. Avoid nylons, like pantyhose, when possible. Keep your feet clean and dry. Wear "breathable" shoes.

In public areas like locker rooms or swimming pools, wear "flip flops" or other sandals if you can. Otherwise, wash and dry your feet well afterward. Don't share towels or washcloths.

Nail polish may invite fungus because it does not allow the nails to "breathe." If you have nail fungus, don't wear any polish or artificial nails until the fungus is gone. If you have a tendency to get nail fungus, you may need to go without nail polish altogether.

In those prone to toenail fungus, powder such as that used to treat athlete's foot can help keep feet dry and prevent fungus from recurring. This won't cure nail fungus if you already have it, though.

People with nail fungus are often very self-conscious about their condition. They wear shoes and socks all the time so that others won't see their nails, but this can cause the feet to sweat and encourage the growth of the fungus. It's important to know that there is effective treatment available for nail fungus.

If you think you have nail fungus, you should see a doctor for treatment. If you have toenail fungus, you may want to see a foot specialist called a podiatrist. A podiatrist will often file away the infected part of the nail. Don't try to do this yourself. If you have diabetes, definitely don't try to cut or file the nail yourself. Let the doctor do it.
