How Does One Get Toenail Fungus?

Infection

Toenail fungus is an infection for which the medical term is onychomycosis. One or more of your nails will thicken, become brittle or crumbly and may start to shed. The nail also can become distorted, dull or dark because of debris that builds up under it. The affected nails can be yellow or brown. Fungus can be present because of abnormal acidity levels in the skin, trauma to the nail or poor hygiene. It is believed that toenail fungus, like athlete's foot, can be picked up while walking barefoot in locker rooms or in public showers. You are also at risk for developing nail fungus if you perspire heavily, work in a humid or moist environment, have psoriasis, wear socks and shoes that are not well ventilated or have diabetes, resulting in circulation problems and a weakened immune system.

Moist Places

Toenail fungus is relatively common. It is estimated that more than 10 percent of the population has toenail fungus. Some people are more susceptible than others. The fungi are attracted to warm, moist places, according to Toenailfungus.org. When the fungus begins growing on one toenail, it can easily spread to the other nails. Try to wear sandals if you are in public swimming pools, spas, locker rooms or showers. This will keep your feet from touching the floor directly. Or be sure to wash your feet thoroughly and dry them well. If you have toenail fungus, be considerate of others. Use the towel only once when drying your feet and then wash it. Do not share your towels or washcloths with other people so you won't spread the fungus. Use a paper towel to dry the affected area and then throw it away.

Microscopic

Sometimes the condition can become painful if the infected nails separate from the nail bed, explains the Mayo Clinic. Toenail fungus needs to be treated or it will persist indefinitely. See your doctor at the first sign of toenail fungus. It may start with a tiny white or yellow spot under the tip of your nail. Fungi are microscopic organisms that can easily invade the skin through tiny invisible cuts or small separations between the nail and nail bed. They will cause problems when continually exposed to warmth and moisture. There is little blood circulation to the toes so it makes it hard for the body's immune system to work against the infection. The toenail is a protective covering that allows the fungus to keep growing. The older you are the more at risk for toenail fungus you are because of diminished blood circulation to the area. The nails also grow more slowly and thicken with age, making them susceptible to infection.
