Key Takeaways
- Toenail fungus is a common infection that causes thick, discolored, and brittle toenails.
- It thrives in warm, moist environments like sweaty socks and communal showers.
- Risk increases with age, poor foot hygiene, or weakened immune systems.
- Early treatment is key to preventing spread and nail damage.
- At Sole Foot and Ankle, customized treatment plans include topical medication, oral antifungals, and laser therapy.
What Is Toenail Fungus?
Toenail fungus, also called onychomycosis, is a fungal infection that affects the nails—most often the toenails. Fungi invade through tiny cracks in the nail or surrounding skin, causing the nail to become thick, discolored, and brittle over time. This condition is commonly seen in adults but can affect people of all ages.
When left untreated, the infection can spread to other nails or the surrounding skin. This may lead to discomfort when walking, embarrassment, or secondary infections. At Sole Foot and Ankle, we often treat toenail fungus in patients who want both relief and confidence restored.
Causes and Risk Factors for Toenail Fungus
How Does Toenail Fungus Start?
Fungi such as dermatophytes are responsible for most nail infections. These organisms thrive in environments that are warm, dark, and moist—exactly like the inside of your shoes.
Risk Factors
Several factors can increase your risk of developing toenail fungus:
- Age: The risk increases with age due to slower nail growth and reduced blood circulation.
- Poor Foot Hygiene: Not drying feet properly or wearing damp socks.
- Sweaty Feet: Excess moisture creates a perfect environment for fungus.
- Walking Barefoot in Communal Areas: Locker rooms, public showers, and swimming pools.
- Footwear Choices: Tight, non-breathable shoes trap heat and sweat.
- Medical Conditions: Diabetes, poor circulation, or a weakened immune system.
Symptoms to Watch For
Toenail fungus often develops slowly, making early symptoms easy to overlook. Watch for the following signs:
- Thickened nails
- Yellow, brown, or white discoloration
- Brittleness or crumbling edges
- A distorted or warped nail shape
- Separation of the nail from the nail bed
- Foul odor
- Pain when wearing shoes or walking
Diagnosis and Testing
At Sole Foot and Ankle in Valparaiso, our podiatrists use a detailed approach to confirm toenail fungus.
- Physical Examination: We assess nail appearance, foot hygiene, and your medical history.
- Lab Testing: In some cases, a nail clipping may be sent to a lab to identify the specific fungus involved.
- Additional Tools: A Wood’s lamp (UV light) or microscopic evaluation may be used to detect fungal activity.

Treatment Options
Effective treatment depends on the severity and type of fungal infection. At Sole Foot and Ankle, our podiatrists design personalized plans that target the root of the problem.
Treatment Option | Purpose | Who It’s Best For |
---|---|---|
Topical Antifungal Creams | Kill fungus on the surface of the nail | Mild infections; early-stage cases |
Oral Antifungal Medication | Targets infection from within | Moderate to severe infections; faster results |
Laser Therapy | Uses light to destroy fungus deep inside | Patients who prefer a drug-free, non-invasive option |
Nail Debridement | Reduces thickness and removes infected nail | Severe or painful infections |
Antifungal Nail Lacquer | Applied like nail polish to inhibit fungus | Patients seeking convenience and cosmetic care |
Many treatments require consistency and patience. Fungal nails can take months to grow out fully clear, even with effective treatment.
Preventive Care Tips
You can reduce your chances of developing toenail fungus or reinfection with a few simple steps:
- Dry feet thoroughly after bathing—especially between the toes.
- Wear moisture-wicking socks and change them daily.
- Choose breathable shoes made of mesh or leather.
- Avoid walking barefoot in locker rooms, gyms, or pool areas.
- Disinfect nail clippers and avoid sharing them.
- Let your feet “air out” when possible.
- Use antifungal powder or spray if you’re prone to sweaty feet.
When to See a Podiatrist
Toenail fungus doesn’t usually go away on its own—and the longer it’s ignored, the harder it becomes to treat.
Seeing a podiatrist early can prevent long-term nail damage, pain, or spread to other toes. If you’ve noticed changes in your toenails that aren’t improving, our team can help.

Frequently Asked Questions (FAQs)
- Is toenail fungus permanent?
No. Toenail fungus is treatable, especially when caught early. With the right treatment plan, healthy nails can grow back over time. - Will I need to remove the infected nail?
Not usually. In most cases, conservative treatments are effective. In severe cases, partial nail removal may be recommended to allow medications to work more effectively. - Can toenail fungus spread?
Yes. It can spread to other toenails, the skin (causing athlete’s foot), or even to other people. That’s why early treatment is important. - What’s the fastest way to get rid of toenail fungus?
Laser therapy and oral antifungal medications often work more quickly than topical treatments. Your podiatrist will recommend the best option based on your condition.
