Causes of Toenail Fungus

Toenail fungus, also known as onychomycosis, is primarily caused by a type of fungi called dermatophytes. The fungi thrive in warm, moist environments. Common sites of infection include public pools, showers, and locker rooms, where the fungus easily spreads from one person to another through direct contact with contaminated surfaces. The risk of developing toenail fungus increases with various factors, such as wearing tight, non-breathable shoes that trap moisture, having a minor nail or skin injury around the nail, or having a weakened immune system. Low blood circulation and slow nail growth can make people susceptible to contracting toenail fungus. Keeping the feet clean and dry, wearing breathable footwear, and using antifungal sprays or powders in shoes and socks can help reduce the chances of contracting toenail fungus. If you are suffering from toenail fungus, it is suggested that you make an appointment with a podiatrist today. 

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 Ocotillo Foot and Ankle Centers. Our doctors can provide the care you need to keep you pain-free and on your feet.


  • 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


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.


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.
