Toenail Fungus: What’s Really Behind It and the Best Ways to Eliminate It for Good!
Toenail fungus might not sound like a big deal, but for many adults, especially those over 55, it’s more than just a cosmetic concern. Toenail fungus can cause pain, discomfort, and embarrassment, and it doesn’t go away on its own. In fact, nearly 1 in 2 people over 70 are affected by toenail fungus. If you notice your toenail starting to thicken, yellow, or crack, it’s important to act quickly.
Why is toenail fungus so common, and what can you do about it? We spoke with Connecticut-based podiatrist Dr. Arnold J. Zuckman, who explains the reasons behind the rise in toenail fungus cases in older adults and what treatments are worth trying.
Toenail Fungus Becomes a Bigger Issue as We Age
“Fungal infections are opportunists,” explains Dr. Zuckman. “As we age, our nails grow slower, our circulation declines, and our immune system works harder. That creates the perfect environment for fungus to take hold.”
Here are a few reasons why toenail fungus is more common in adults over 55:
- Slower Nail Growth: As we age, our nail growth slows, allowing more time for fungus to spread under the nail.
- Cracked or Brittle Nails: Older adults often have cracked or brittle nails, making it easier for fungus to invade.
- Foot Conditions: Chronic foot conditions like diabetes or neuropathy increase the risk of fungal infections.
- Poor Circulation: Reduced circulation to the feet makes it harder for the body to fight off infections.
- Years of Wear and Tear: Tight shoes, public showers, and nail salons increase the risk of developing toenail fungus.
It’s not just about appearance. If left untreated, toenail fungus can lead to pain, difficulty walking, and even secondary infections—especially for people with underlying conditions like diabetes or weakened immune systems.
What Does Toenail Fungus Treatment Look Like in 2025?
Treating toenail fungus requires patience and consistency. It’s not an overnight fix, but with the right treatment, progress is possible. Here are some effective options for treating toenail fungus:
- Prescription Pills: Oral antifungals like terbinafine (Lamisil) are highly effective for treating toenail fungus. These pills work from the inside out but may require monitoring for liver health. Most people need to take them for 6–12 weeks.
- Topical Treatments: Medicated nail lacquers such as Jublia or Penlac are effective for mild toenail fungus infections, or if oral medications aren’t an option. They must be applied daily for best results.
- Laser Therapy: This newer treatment uses light energy to kill the fungus under the nail. It can be pricey and may not be covered by insurance, but many patients see improvements after a few sessions.
- At-Home Remedies: Natural remedies such as tea tree oil, Vicks VapoRub, or soaking feet in Listerine have gained popularity. While not proven cures, they may help slow the spread of the fungus and keep things from getting worse.
“If your toenail has been thick and yellow for a while, don’t just file it down and ignore it,” advises Dr. Zuckman. “See a specialist early to make treatment more effective.”
Can Toenail Fungus Be Prevented?
Yes! Toenail fungus is preventable, especially if you’ve had it before. Fungus thrives in damp, dark environments, which makes shoes, socks, and communal spaces like gym showers the perfect breeding grounds. Dr. Zuckman offers several practical tips to prevent toenail fungus:
- Daily Foot Hygiene: Wash and dry your feet thoroughly every day, making sure to dry between the toes.
- Breathable Shoes and Moisture-Wicking Socks: Wear well-fitting shoes made of breathable materials and moisture-wicking socks to prevent sweaty feet.
- Rotate Shoes: Change your socks daily and rotate your shoes to give them time to air out.
- Avoid Communal Showers: Never walk barefoot in public spaces like locker rooms or hotel showers, where fungal infections can spread.
- Disinfect Nail Tools: Clean your nail tools and never share them with others.
- Use Antifungal Powders: If your feet sweat excessively, consider using antifungal powders to keep your feet dry and prevent fungus growth.
“Foot hygiene isn’t glamorous,” Dr. Zuckman says with a laugh, “but it’s incredibly important.”
