Definition of Toenail Fungus

Onychomycosis is a fungal infection that affects the toenails, causing them to become thickened, discolored, brittle, and sometimes painful. It is often caused by fungi that thrive in warm, moist environments such as shoes, locker rooms, and public showers. Risk factors include excessive sweating, poor foot hygiene, or a weakened immune system. Symptoms include yellow or white streaks on the nail, foul odor, or nail separation from the nail bed. A podiatrist can diagnose the infection through examination and testing, then recommend antifungal medications, laser therapy, or nail debridement. If you notice changes in your toenails, it is suggested that you schedule an appointment with a podiatrist who can provide appropriate treatment for toenail fungus.

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. For more information about treatment, contact One of our podiatrists of Foot and Ankle Medical Center. Our doctors can provide the care you need to keep you pain-free and on your feet.

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.
