Toenail Fungus: Treatment and Prevention

A thick, yellowish nail with splotchy white areas is a classic presentation for a fungal toenail. In the early stages the toenail is only slightly discolored, or slightly thickened. In the late stages the nail can become very thick and has a tendency to "grow up" more than in grows out. The nail will be very discolored, typically dark yellow-brown and will start to change shape and crumble. In some cases the nail becomes very loose and many will lose the nail, only for it to regrow with the fungus.

The medical term for toenail fungus is "onychomycosis," pronounced on * EE * ko * my * ko * sis. The prevalence in America is about 2-3%, but some have reported it as high as 13%. Toenail fungus affects men twice as often as it affects women and the prevalence among elderly individuals and diabetics is 25%. In the 1800s, fungal toenails were very rare. The increased prevalence is linked to the increased exposure to fungus through the use of showering facilities in gyms, the use of hot tubs, saunas and public pool areas. There has also been an increase in the number of individuals participating in sporting activities and wearing occlusive footwear. More individuals have diabetes and there has been an overall increase in age of the general population, both of which are associated with a less than optimal immune system. It is no surprise that the risk factors for developing toenail fungus are increasing age, male gender, nail trauma, sweaty feet, poor circulation, poor hygiene, foot fungus and a compromised immune system. Athletes will also have a higher risk.

There are a number of treatments for toenail fungus. The most aggressive and effective way to treat the fungus is with oral anti-fungal medications. The most common oral anti-fungal medications are Itraconazole (Sporonox
