Fungal toenails, also known as onychomycosis, are a common condition that occurs when a fungus infects the toenails, causing them to become thick, discoloured, and brittle. Fungal toenails are more common in adults, and are often accompanied by a foul odour. They can cause discomfort, difficulty walking and embarrassment from the colour/smell.

Fungal toenails are caused by a variety of fungi, including dermatophytes, yeasts, and moulds. They thrive in warm, moist environments, and can be transmitted through contact with contaminated surfaces or through direct contact with an infected person. Risk factors for developing fungal toenails include:

• Wearing tight, synthetic shoes that do not allow the feet to breathe

• Sweaty feet

• Having a compromised immune system, diabetes or poor circulation

Symptoms of a fungal infection consist of thick, discoloured, and brittle toenails, which makes them difficult to cut. The afflicted nails may have a foul odour, and pain and discomfort can be experienced when walking or wearing shoes.

Treatment for fungal toenails may include:

• Using over-the-counter or prescription antifungal creams or ointments

• Applying laser therapy

• If none of the above are effective, removing the infected toenail surgically

To prevent fungal toenails, it is important to keep the feet clean and dry, especially in warm, moist environments. Wearing shoes that fit properly and allow the feet to breathe can also help to prevent the condition. Avoiding sharing towels or shoes with others can also help to prevent the spread of fungal toenails, as well as walking barefoot in communal areas, such as public swimming pools and change rooms.

If you are experiencing symptoms of fungal toenails, it is important to seek a podiatrist to receive a proper diagnosis and treatment. With proper care and prevention, fungal toenails can be effectively treated and prevented from recurring.
