Toenail fungus, known as onychomycosis, affects the toenails. It develops when fungi enter through cracks in the nail or skin. Infection can cause nails to become thick, brittle, discolored, or misshapen. Affected nails may appear yellow, white, or brown and sometimes develop an odor. As the infection progresses, pain or tenderness may develop, especially when shoes place pressure on the toe. Thickened nails can become difficult to cut and maintain.
Several factors can increase the risk of developing toenail fungus. Warm, damp environments create conditions where fungi thrive. Sweaty feet and wearing closed shoes can increase moisture around the nails. Walking barefoot in shared showers, gyms, or locker rooms can increase exposure. Previous toenail injuries may provide an opening for infection. Poor circulation and certain chronic health conditions can increase vulnerability. Keeping feet clean and dry can help lower the risk.
A podiatrist can diagnose toenail fungus by examining the affected nail and skin while reviewing your symptoms and history. In some cases, a small nail clipping or scraping is sent for laboratory testing to confirm the infection and identify the fungus. Treatment depends on the severity and type of infection. Options may include professional nail trimming or thinning, prescription antifungal medication, or laser therapy. Because toenails grow slowly, recovery requires patience and consistent treatment.
Early evaluation can help prevent toenail fungus from becoming more severe or difficult to manage. If you notice changes in nail color, thickness, or shape, a podiatrist can determine whether fungus is responsible or whether another condition is causing the changes. Podiatric care can provide an accurate diagnosis, appropriate treatment, and ongoing monitoring as healthy nail growth occurs. If you have symptoms of toenail fungus, it is suggested that you consult a podiatrist for evaluation 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.
