FUNGUS
TOENAILS
By: Corinne Gehegan, DPM
 Fungus is responsible for both skin and nail conditions of the feet.
Fungus is the cause of tinea pedis which is better known as athlete’s
foot. This skin condition can manifest itself in between the toes, at
the bottom and sides of the feet, or both. Occasionally, the condition
affects only one foot. Many conditions can mimic athlete’s foot;
therefore, it is a good idea to consult a podiatrist before spending
money on over the counter products. Athlete’s foot does not always cause
an itch. Many times it presents as dry, scaly skin and people will treat
it as such. The problem is that lotions and creams without antifungal
properties may simply foster the moist environment that fungus thrive
in.
Fungus is also the cause of the dreaded fungal nail. The medical term
for this condition is onychomycosis. Onychomycosis causes changes in the
nail such as thickening, discoloration, powdery debris beneath the nail,
and separation of the nail from the underlying skin. Many times an
individual will be unaware of having a chronic case of athlete’s foot.
Eventually, the fungus that caused the athlete’s foot will transfer to
the nail(s). In some instances, fungus will have the opportunity to
invade the nail if the nail has undergone a traumatic event. It may even
be introduced during a pedicure.
Prevention is ideal as these conditions can be difficult to manage.
Fungus survives in warm, dark, moist places. A shoe is the perfect
example of this environment. This is why these conditions rarely affect
the hands. The hands can become infected if the individual has an
occupation which requires his hands to be immersed in water for long
periods of time. Likewise, people who garden without gloves may also
become infected because fungus is present in soil.
Changing socks/nylons daily or even twice daily is optimal. Avoid
wearing the same shoes everyday. Socks should be made of a
natural/synthetic blend that wicks moisture from the feet. Shoes should
be made of natural materials as well. Applying powder directly to your
feet is a good idea as is spraying the inside of the shoes with an
antifungal spray. If you suspect fungus, particularly of the nails,
avoid soaking your feet in warm water as this will encourage moisture
within and under the nails. Make every effort to avoid walking barefoot
on the floors in public places such as spas, gyms, and hotels.
Treatments involve both topical and oral medications. Your podiatrist
can discuss the risks and benefits of both. He/She can also determine if
you are the right candidate for oral medication.
