Toenail fungus, or onychomycosis, is an infection underneath the surface of the nail caused by fungi. When the tiny organisms take hold, the nail often becomes darker in color and smells foul.
Onychomycosis can also be accompanied by a secondary bacterial or yeast infection in or about the nail plate.
Those who suffer from chronic diseases, such as diabetes, circulatory problems, or immune-deficiency conditions, are especially prone to fungal nails. Other contributing factors may be a history of athlete’s foot and excessive perspiration
Oral antifungals, approved by the Food and Drug Administration, may be the most effective treatment. They offer a shorter treatment regimen of approximately three months and improved effectiveness.
After a fungal toenail infection has cleared up it is important to take steps to prevent the infection from recurring.
Keeping fungi at bay will help prevent a fungal infection of the skin from reinfecting the nail. Before bed, thoroughly wash and dry your feet, and apply a nonprescription anti-fungal cream to the entire foot from the ankle down. Use the cream every night, then gradually apply it less often. Keep your feet dry. Dry feet are less likely to become infected. Apply powder to your dry feet after you take a shower or bath.
