What Causes Discolored Nails?

Toenail fungus can begin with a change in the color of a nail. A white or yellow spot may appear before the nail becomes thicker or brittle. The nail might crack, lift from the skin, or collect material underneath. This infection develops when fungi enter the nail or openings in nearby skin. It frequently affects the big toe or second toe. Although some people feel no discomfort, others develop pain that makes standing or walking difficult. The appearance of an infected nail can cause embarrassment. Without treatment, the infection can spread to other nails.

Toenail fungus is contagious and can pass between people through contact with infected skin or nails. Shared nail clippers and towels can carry the fungus. Warm, damp public spaces, like locker rooms and pool decks, create opportunities for exposure. Athlete's foot, a fungal infection of the skin, can spread into a toenail. Having dirty nails alone does not cause this condition. Changes in nail color do not necessarily mean a fungus is present, however. A podiatrist can examine the affected nail and collect a sample for testing to confirm the diagnosis.

Toenail fungus rarely clears without treatment because fungi can remain inside and beneath the nail. Scraping or filing the surface does not remove the infection. A podiatrist can prescribe antifungal medications applied to the nail or taken by mouth. The choice depends on the extent of infection and the patient's health. Treatment can clear the fungus before the nail looks normal again. Toenails grow slowly, so a healthy-looking big toenail may take a year or longer to return. Early diagnosis makes treatment more effective and helps prevent spread. If you have symptoms of toenail fungus, it is suggested that you schedule an appointment with a podiatrist for diagnosis and treatment.

If left untreated, toenail fungus may spread to other toenails, skin, or even fingernails. If you suspect you have toenail fungus it is important to seek treatment right away.

Symptoms

  • Warped or oddly shaped nails
  • Yellowish nails
  • Loose/separated nail
  • Buildup of bits and pieces of nail fragments under the nail
  • Brittle, broken, thickened nail

Treatment

If self-care strategies and over-the-counter medications does not help your fungus, your podiatrist may give you a prescription drug instead. Even if you find relief from your toenail fungus symptoms, you may experience a repeat infection in the future.

Prevention

In order to prevent getting toenail fungus in the future, you should always make sure to wash your feet with soap and water. After washing, it is important to dry your feet thoroughly especially in between the toes. When trimming your toenails, be sure to trim straight across instead of in a rounded shape. It is crucial not to cover up discolored nails with nail polish because that will prevent your nail from being able to “breathe”.

In some cases, surgical procedure may be needed to remove the toenail fungus. Consult with your podiatrist about the best treatment options for your case of toenail fungus.
