If you have been noticing changes in your toenails, you are not alone. Toenail fungus, known medically as onychomycosis, is one of the most common nail conditions in the United States, affecting an estimated 10 percent of the general population and up to 50 percent of people over the age of 70. And summer, with its heat, humidity, and increased exposure to public spaces, is the season when fungal nail infections most frequently take hold and worsen.

At Diablo Foot & Ankle, we treat toenail fungus at our clinics in Antioch, Walnut Creek, and San Ramon. One of the most important things we tell our patients is this: toenail fungus does not go away on its own. The sooner you seek treatment, the simpler and more effective the process will be.

What Is Toenail Fungus?

Toenail fungus is an infection caused by dermatophytes, a group of fungi that feed on keratin, the protein that makes up your nails and skin. Less commonly, the infection can be caused by yeasts or molds. The fungi enter the nail through small cracks or separations between the nail and nail bed, and once established, they are protected by the nail itself, making them difficult to eliminate without targeted treatment.

The condition typically begins as a small white or yellow spot under the tip of the nail. As the infection progresses, it can cause the nail to become:

• Thickened and difficult to trim
• Discolored (yellow, brown, or white)
• Brittle, crumbly, or ragged at the edges
• Distorted in shape
• Separated from the nail bed (a condition called onycholysis)
• Accompanied by a faint odor

In advanced cases, the infection can spread to other toenails or to the skin of the foot, causing athlete's foot. For patients with diabetes or compromised immune systems, untreated toenail fungus can lead to more serious complications, including bacterial infections and ulcers.

Why Summer Makes It Worse

Summer creates ideal conditions for fungal growth and transmission. Understanding the specific risk factors can help Antioch residents take targeted preventive action.

Warm, Moist Environments: Fungi thrive in warm, damp conditions. Sweaty feet inside shoes, wet pool decks, gym locker rooms, and communal showers are all high-risk environments. Antioch's warm summer temperatures mean that feet are more likely to sweat, and residents are more likely to spend time in these shared spaces.

Sandals and Open-Toe Shoes: While sandals reduce the sweaty environment inside closed-toe shoes, they expose the toenails to direct contact with contaminated surfaces. Walking barefoot on a pool deck or gym floor is one of the most common ways toenail fungus is acquired.

Nail Salons: Pedicures are popular in summer, but nail salons that do not properly sterilize their tools between clients can be a source of fungal transmission. If you get pedicures, choose salons that use autoclaved instruments or bring your own tools.

Tight or Ill-Fitting Footwear: Shoes that crowd the toes create microtrauma to the nail, making it easier for fungi to gain entry. Summer athletic activities in improper footwear compound this risk.

Why You Should Not Wait

This is the message our podiatrists in Antioch, Walnut Creek, and San Ramon want every patient to hear: toenail fungus is a progressive condition. It does not plateau or resolve without treatment. Left untreated, it will spread to more nails, become more deeply embedded, and become significantly harder to treat.

Many patients delay seeking care because they feel embarrassed about the appearance of their nails, or because they assume it is a cosmetic issue rather than a medical one. In reality, toenail fungus is a true infection that can have real health consequences, particularly for patients with diabetes, peripheral vascular disease, or immune system conditions.

The earlier treatment begins, the fewer nails are affected, the less severe the infection, and the faster the results.

Treatment Options at Diablo Foot & Ankle

At Diablo Foot & Ankle, we offer a range of evidence-based treatments for toenail fungus. Our podiatrists will evaluate the severity of your infection and recommend the most appropriate approach for your specific situation.

Topical Antifungal Medications: For mild, early-stage infections, prescription-strength topical antifungals can be effective. These are applied directly to the nail and surrounding skin. While convenient, topical treatments have limited ability to penetrate the nail plate and reach the fungus beneath, which is why they are most effective for superficial infections.

Oral Antifungal Medications: Oral antifungals like terbinafine are more effective than topical treatments for moderate to severe infections because they work systemically, reaching the nail bed through the bloodstream. However, they require a course of treatment lasting several months and may not be appropriate for all patients due to potential interactions with other medications or effects on liver function.

Laser Treatment: Laser therapy is one of the most advanced and effective options available for toenail fungus. The laser emits a specific wavelength of light that penetrates the nail and generates heat that destroys the fungal organisms without harming the surrounding nail tissue or skin. Laser treatment is safe, non-invasive, and requires no anesthesia or downtime.

At Diablo Foot & Ankle, we offer laser treatment for toenail fungus at our Antioch, Walnut Creek, and San Ramon locations. Most patients require a series of sessions, and results become visible as the new, healthy nail grows in over the following months.

What to Expect During Treatment

If you come in to our Antioch clinic for toenail fungus treatment, here is what the process typically looks like.

Initial Evaluation: Your podiatrist will examine your nails and may take a nail sample for laboratory analysis to confirm the diagnosis and identify the specific type of fungus. This helps ensure the most targeted treatment approach.

Treatment Plan: Based on the severity of your infection, the number of nails affected, and your overall health, your podiatrist will recommend a treatment plan. This may involve a single treatment modality or a combination approach.

Follow-Up Care: Toenail fungus treatment requires patience. Because nails grow slowly, it can take six to twelve months to see a fully clear nail after treatment. Your podiatrist will schedule follow-up appointments to monitor your progress and adjust the treatment plan if needed.

Preventive Guidance: Your podiatrist will also provide specific guidance on how to prevent reinfection, including recommendations for footwear, foot hygiene, and how to safely navigate high-risk environments like pools and gyms.

Preventing Toenail Fungus This Summer

While treatment is available and effective, prevention is always preferable. Here are the most important steps Antioch residents can take to reduce their risk this summer.

• Always wear sandals or water shoes on pool decks, in locker rooms, and in communal showers
• Keep feet clean and dry, paying special attention to the spaces between the toes
• Change socks daily and choose moisture-wicking materials
• Trim toenails straight across and avoid cutting them too short
• Disinfect nail clippers and other pedicure tools after each use
• Choose nail salons that sterilize their instruments
• Avoid sharing towels, socks, or shoes with others
• If you have athlete's foot, treat it promptly to prevent it from spreading to the nails
