Fungal Toenails 

What Are Fungal Toenails?

Fungal toenails, also known as onychomycosis, occur when a fungal infection develops under the nail, causing discoloration, thickening, and brittleness. This condition is common and can affect one or multiple toenails. While not always painful, fungal toenails can lead to discomfort, embarrassment, and, in severe cases, complications if left untreated.

​

Causes of Fungal Toenails

Fungal toenail infections are caused by fungi, yeasts, or molds that thrive in warm, moist environments. Common risk factors include:

• Exposure to Fungi – Walking barefoot in public areas like locker rooms, swimming pools, and communal showers increases the risk of infection.

• Poor Foot Hygiene – Not washing and drying feet properly can create an environment for fungal growth.

• Sweaty Feet – Excessive moisture in shoes and socks can contribute to fungal infections.

• Toenail Injuries – A damaged nail or nail bed makes it easier for fungi to enter and cause an infection.

• Weakened Immune System – People with diabetes, circulation issues, or compromised immune systems are more prone to fungal toenail infections.

• Sharing Contaminated Items – Using infected nail clippers, socks, or shoes can spread the fungus.

​

Symptoms of Fungal Toenails

Fungal toenail infections typically develop gradually and may include:

• Yellow, white, or brown discoloration of the nail

• Thickened, brittle, or crumbly nails

• Distorted nail shape

• Separation of the nail from the nail bed

• Foul odor in some cases

• Pain or discomfort when wearing shoes if the nail becomes too thick

​

Treatment for Fungal Toenails

Fungal toenail infections can be stubborn and often require professional treatment for effective removal.

At-Home Remedies:

• Over-the-counter antifungal creams or nail polishes may help in mild cases, though they often take months to show results.

• Keeping feet dry and wearing breathable shoes can help prevent worsening.

• Regularly trimming and filing down thickened nails can reduce discomfort.

Professional Treatment Options:

For moderate to severe infections, a podiatrist may recommend:

• Prescription Oral Antifungal Medications – More effective than topical treatments, these medications help clear the infection from within.

• Topical Prescription Medications – Stronger than over-the-counter options but often require consistent, long-term use.

• Laser Therapy – A non-invasive option that targets and destroys fungal infections.

• Nail Removal (Partial or Complete) – In cases where the infection is severe, removing the affected nail may be necessary to allow a healthy nail to grow back.

​

Preventing Fungal Toenail Infections

To reduce the risk of developing a fungal toenail infection, consider these preventive steps:

• Keep feet clean and dry, especially between the toes.

• Wear moisture-wicking socks and change them regularly.

• Avoid walking barefoot in public places like locker rooms and pool areas.

• Use antifungal powders or sprays if you’re prone to sweaty feet.

• Trim nails properly – Straight across without cutting too short.

• Disinfect nail clippers and tools after each use.

• Choose breathable footwear and avoid wearing tight shoes for long periods.
