Toenail fungus, also known as onychomycosis, is a common fungal infection that affects the nails.
It typically starts as a white or yellow spot under the tip of the toenail and can spread to the entire nail if left untreated.
Toenail fungus can cause the nails to thicken, become discolored, brittle, and crumbly. It may also lead to pain and discomfort. Fungi thrive in warm, moist environments, making toenails a susceptible area for infection.
Causes
The primary cause of toenail fungus is an overgrowth of fungi, typically dermatophytes. However, other types of fungi, such as yeast and mold, can also contribute to the infection. Some common causes and risk factors for toenail fungus include:
Fungal infection spread
Fungal infections can spread from person to person through direct contact with infected individuals or contaminated surfaces, such as public showers, swimming pools, or gyms.
Warm and moist environments
Fungi thrive in warm and moist environments. Wearing damp shoes or socks for extended periods can create an ideal environment for fungal growth.
Tight footwear
Shoes that are too tight or don’t allow proper ventilation can lead to sweating and moisture buildup, creating favorable conditions for fungi to grow.
Injury to the nail
Trauma to the toenail, such as a stubbed toe or repetitive pressure, can damage the nail’s protective barrier and provide an entry point for fungal infections.
Weakened immune system
A weakened immune system, often seen in individuals with conditions like diabetes, HIV/AIDS, or autoimmune diseases, can increase susceptibility to fungal infections, including toenail fungus.
Poor hygiene
Insufficient foot hygiene, not regularly washing and drying the feet, can contribute to the growth of fungi.
Age
The risk of developing toenail fungus increases with age as nails become more brittle and prone to cracks, allowing fungi to enter and infect the nails more easily.
It’s important to note that while these factors increase the likelihood of developing toenail fungus, some people may get infected even without these risk factors.
Symptoms
The symptoms of toenail fungus (onychomycosis) can vary depending on the severity of the infection. Common symptoms include:
Discoloration
The toenail may appear white, yellow, brown, or even black. The color may start as small spots or streaks and gradually spread across the entire nail.
Thickening
The infected toenail may become thick and distorted. It can appear raised or elevated from the nail bed.
Brittleness and crumbling
The infected toenail may become brittle, fragile, and prone to cracking or crumbling. It may become difficult to trim or properly care for the affected nail.
Change in shape
The shape of the affected toenail may distort, becoming irregular or curved instead of its normal flat appearance.
Separation from nail bed
The toenail may separate from the nail bed, resulting in a gap between the nail and the skin underneath. This can cause pain, discomfort, and an increased risk of infection.
Foul odor
In some cases, toenail fungus can cause a foul odor emanating from the infected nail.
The Best Treatment
There are various treatments for toenail fungus, and the most appropriate treatment option depends on the severity and extent of the infection.
It’s important to note that treating toenail fungus can be a long process, and results may take several months. Here are some of the common treatment options:
Topical antifungal medications
Over-the-counter or prescription-strength antifungal creams, ointments, or nail lacquers can be applied directly to the infected toenail. These medications typically need to be used consistently for several months to see improvement.
Oral antifungal medications
In some cases, oral medications may be prescribed to treat toenail fungus. These medications work systemically and can be more effective for severe infections, but they may have potential side effects and require regular monitoring.
Laser therapy
Laser treatment is a newer option that involves targeting the fungus with a laser beam to destroy it. This treatment is usually done in a doctor’s office and may require multiple sessions.
Surgical removal
If the infection is severe or causing significant pain, a healthcare professional may recommend surgically removing the affected toenail. This can be done in combination with other treatments to improve effectiveness.
Home remedies
Some people may choose to try natural remedies, such as applying tea tree oil, vinegar, or essential oils to the affected nail.
While these home remedies may show some anecdotal success, scientific evidence for their effectiveness is limited.
Tips to Prevent toenail fungus
While prevention is not always guaranteed, following these tips may help reduce the risk of toenail fungus:
Keep feet clean and dry
Wash your feet daily with soap and water, ensuring you dry them thoroughly afterward, especially between the toes. Moisture promotes fungal growth, so it’s crucial to keep your feet dry.
Trim nails properly
Trim your toenails straight across and avoid rounding the edges. This helps prevent ingrown nails, which can create a favorable environment for fungal infections.
Wear breathable shoes and socks
Choose shoes made of breathable materials like leather or mesh to allow proper air circulation. Wear moisture-wicking socks that help keep your feet dry.
Change shoes and socks regularly
Avoid wearing damp or sweaty shoes and socks for prolonged periods. If your feet tend to sweat excessively, consider changing your socks during the day or using antifungal foot powder.
Protect your feet in public spaces
Wear protective footwear, such as shower shoes or sandals, in public showers, locker rooms, and pool areas to avoid direct contact with surfaces that may harbor fungi.
Don’t share personal items
Avoid sharing towels, socks, shoes, or other personal items with others, as this can increase the risk of fungal transmission.
Use antifungal sprays or powders
If you’re prone to fungal infections, apply an antifungal powder or spray to your feet and inside your shoes to help prevent fungal growth.
Maintain healthy feet
Practice good foot hygiene by regularly moisturizing your feet with a fungus-fighting foot cream and regularly examining your nails for any signs of infection.
If you notice any signs of toenail fungus, such as discoloration, thickening, or brittleness of the nails, consult a dermatologist for proper diagnosis and treatment.
