Causes and Symptoms of Toenail Fungus

Toenail fungus, or onychomycosis, is a fungal infection that affects the toenails, often leading to noticeable changes in their appearance. Toenail fungus can cause discoloration, thickening, and crumbling of the nail, sometimes resulting in separation from the nail bed. The infection is primarily caused by dermatophytes, a type of fungus that thrives in warm, moist environments, like the inside of shoes. Factors such as excessive sweating,  wearing tight footwear, nail trauma, or an existing fungal infection can increase the risk of developing toenail fungus. People with a weakened immune system or conditions like diabetes or poor circulation are at a higher risk. Symptoms of toenail fungus include discoloration, often yellow or brown, and changes in the texture of the nail. In severe cases, the nail may become painful or difficult to trim. If you notice changes in the appearance of your toenails, it is suggested that you schedule an appointment with a podiatrist for a diagnosis and appropriate 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.
