Nail fungus, or onychomycosis, is a common condition that occurs when fungi infect the nail bed, causing discoloration, thickening, and brittleness. The fungi that cause nail fungus thrive in warm, moist environments, such as nails, skin, and public spaces like pool decks and locker rooms. Walking barefoot in these areas or sharing nail grooming tools can increase the risk of contracting nail fungus. While it typically starts as mild discoloration or lifting, nail fungus can progress and lead to nail detachment and pain. Treatment options include topical antifungals, oral medications, and, in severe cases, nail removal to allow for healthy nail regrowth.

What You'll Learn
Nail fungus thrives in warm, moist places
Nail fungus, or onychomycosis, is a common condition that can affect both the fingernails and toenails. It is caused by several types of fungi that grow and thrive in warm, moist places, such as people's nails, skin, and communal areas like pool decks, locker rooms, and public showers. The fungi can also survive on everyday objects such as unwashed shower floors, towels, and nail grooming tools, making it easy to transmit the infection through touch.
Fungal nail infections often begin with mild nail discolouration, usually in shades of white, yellow, green, brown, or a combination of these colours. As the infection progresses, the nail may thicken, become brittle, distorted, or misshapen, and even fall off without treatment. While nail fungus is not typically a serious concern, it can cause discomfort and affect the use of the affected hand or foot. Additionally, the relapse rate for toenail fungus is high, at up to 53%.
To prevent nail fungus, it is important to maintain good nail hygiene. This includes keeping your nails trimmed, dry, and clean. Avoiding walking barefoot in damp communal areas and wearing footwear in such places can also reduce the risk of contracting nail fungus. It is advisable to seek medical attention if you suspect a nail fungus issue, as treatments can take a long time and early intervention can prevent the infection from worsening.
If you have a weakened immune system or underlying conditions such as diabetes, it is crucial to promptly address toenail fungal infections to avoid potential complications. In severe cases, a healthcare provider may suggest removing the nail and using chemicals to destroy the nail matrix to prevent the infection from recurring. Oral medications like Sporanox (Itraconazole) or Lamisil (terbinafine) are typically more effective than topical treatments, but they carry a risk of liver damage and must be used with caution.

Athlete's foot is a common cause
Nail fungus, or onychomycosis, is a common condition that can affect both the fingernails and toenails. It is caused by several types of fungi that grow and thrive in warm, moist environments, such as sweaty socks, communal showers, and locker rooms. One of the most common causes of nail fungus is athlete's foot, a fungal skin infection that affects the feet.
Athlete's foot is a condition that often develops between the toes, causing flaky skin, cracks, and itchiness. The same fungi that cause athlete's foot can lead to nail fungus if they slip into an opening in or under the nail. This typically occurs when individuals with athlete's foot touch their nails or walk barefoot in contaminated areas.
Fungal nail infections usually start with mild nail discoloration, often appearing as white, yellow, or brownish spots. As the infection progresses, the nails may thicken, become brittle, and crumble. In more severe cases, the nail may detach from the nail bed, causing pain and difficulty walking.
To prevent nail fungus, it is important to maintain good nail hygiene. Keeping the nails trimmed, dry, and clean can help reduce the risk of infection. Additionally, avoiding walking barefoot in damp communal areas and wearing appropriate footwear can also lower the chances of contracting nail fungus.
If you suspect you have nail fungus, it is important to seek medical attention. A healthcare professional can examine your symptoms and provide a proper diagnosis and treatment plan. Treating nail fungus early is crucial to prevent it from worsening and causing further damage to the nail.

It can spread through contact with infected people or items
Nail fungus is caused by several types of fungi that grow in warm, moist places, such as people's skin, nails, and pool decks. These fungi can also thrive on everyday objects like unwashed shower floors, nail grooming tools, and towels, making nail fungus highly contagious.
One of the main ways nail fungus spreads is through contact with infected individuals. If someone has nail fungus or athlete's foot, touching the affected area can lead to the transfer of fungi. Walking barefoot on contaminated floors, such as in locker rooms, public showers, or around pools, also increases the risk of contracting nail fungus.
In addition to direct contact with infected individuals, nail fungus can spread through shared use of personal care items. This includes sharing unwashed towels, shoes, or nail grooming tools, such as nail clippers, that have not been properly disinfected. It is important to disinfect and dry these items regularly to prevent the spread of fungi.
Furthermore, nail fungus can develop due to prolonged exposure to moisture on the hands or feet. For example, wearing wet shoes or gloves, keeping sweaty socks on, or engaging in activities that constantly wet the hands can create an environment conducive to fungal growth. If fungi spread to a break in the nail or the skin around it, a nail fungus infection can occur.
To prevent the spread of nail fungus, it is crucial to maintain good nail hygiene. This includes keeping nails trimmed, dry, and clean. Additionally, wearing footwear in public places, especially damp communal areas, can help reduce the risk of contracting or spreading nail fungus.

Treatment can take a long time
Treatment for nail fungus can take a long time. It is important to seek medical attention if you suspect a nail fungus issue. A pharmacist may suggest an antifungal nail medicine that you brush onto the nail. You will need to use this regularly for a few months before you start to see an improvement. It may take 12 to 18 months for a nail fungus infection to completely clear up and for fresh growth to fully replace the damaged nail.
It is crucial to keep using the treatment until you are told to stop by a healthcare professional. Stopping treatment early could cause the infection to return. If treatments from a pharmacy do not work, your doctor may prescribe antifungal tablets. Before starting treatment, your doctor will take a sample of your nail to test what kind of infection you have. They may also need to do a blood test before and during your treatment to check that your liver is functioning properly. You may need to take antifungal tablets for up to six months.
The relapse rate for toenail fungus infection is up to 53%. It is important to address toenail fungal infections promptly, especially if you have certain conditions such as diabetes or a weakened immune system. Preventing nail fungus is largely a matter of maintaining good nail hygiene. Keep your nails trimmed, dry, and clean. Wear footwear in public places, especially in warm, moist areas like locker rooms and pool decks. Avoid walking barefoot in such environments, and avoid sharing nail-grooming tools without properly disinfecting them.

Prevention includes keeping your feet dry and clean
Preventing nail fungus is largely about maintaining good nail hygiene. The fungi that cause nail infections thrive in warm, moist places, so keeping your feet dry and clean is essential. Here are some tips to help you keep your feet in tip-top condition and reduce the risk of nail fungus:
Keep your feet clean by washing them regularly and drying them thoroughly, especially between the toes. Fungi can multiply in warm, dark, and moist environments, so ensure your feet are dry before putting on socks and shoes. If you have sweaty feet, change your socks during the day to keep them dry.
Avoid walking barefoot in damp communal areas such as locker rooms, shared showers, or around swimming pools. These areas are often contaminated with fungi, and the fungi that cause nail fungus can enter through microscopic openings in or under your nails. Always wear flip-flops or shower shoes in these areas.
Choose well-fitting, breathable shoes that allow your feet to stay cool and dry. Avoid tight shoes that make your feet sweat. Also, be mindful of wearing shoes that are too loose, as they can cause friction and lead to nail injuries, making it easier for fungi to enter.
Keep your toenails trimmed and properly filed. Long or improperly cut nails can make you more susceptible to nail fungus. When trimming your nails, ensure you use clean nail clippers and disinfect them after each use. This is especially important if you share your nail-grooming tools with others.
If you have a condition that makes your feet sweaty, such as hyperhidrosis, manage it effectively. Fungi thrive in moist environments, so keeping your feet as dry as possible is crucial. Speak to your healthcare provider for advice on managing excessive sweating.
By following these simple steps, you can significantly reduce your risk of developing nail fungus. Keeping your feet clean, dry, and well-groomed creates an unfavourable environment for fungi, helping you maintain healthy and happy feet!
