Fungal nail infections are one of the most common foot problems seen by a podiatrist. They often start subtly, but if left untreated, they can become persistent, unsightly, and sometimes uncomfortable.
Many people assume it’s just a cosmetic issue, but fungal nails can affect confidence, foot health, and even how you walk if the nail thickens or becomes painful.
In this article, we’ll explain what causes fungal nail infections, how to spot them early, and the most effective treatment options available.
What is a fungal nail infection
A fungal nail infection, sometimes called onychomycosis, occurs when fungi enter the nail through small cracks or damage in the nail or surrounding skin.
The infection can affect one nail or several and is more common in toenails than fingernails.
Over time, the nail may become:
Discoloured (yellow, white, or brown)
Thickened or distorted
Brittle or crumbly
Separated from the nail bed
In some cases, there may also be discomfort when wearing shoes.
Common causes and risk factors
Fungal nail infections thrive in warm, damp environments, which makes feet particularly vulnerable.
Common causes include:
Wearing tight or non-breathable footwear
Sweaty feet or poor foot hygiene
Using communal areas such as gyms, swimming pools, or changing rooms
Minor nail trauma, such as stubbing your toe
Existing skin infections like athlete’s foot
Certain people are more at risk, including:
Those on their feet all day for work
Runners and active individuals
Older adults, as nails become thicker and harder to care for
People with underlying health conditions affecting circulation
How a podiatrist treats fungal nail infections
While over-the-counter treatments are widely available, they are often ineffective once the infection has taken hold.
At a professional podiatry clinic, treatment focuses on both clearing the infection and improving the overall health of the nail.
Treatment may include:
Careful reduction of thickened nails to relieve pressure and improve comfort
Advice on antifungal treatments that are appropriate for your condition
Monitoring nail growth to track improvement
Addressing any underlying causes, such as footwear or biomechanics
In more persistent cases, a podiatrist may recommend advanced treatment options or a combination of approaches to achieve the best result.

Preventing fungal nail infections
Prevention plays a key role in avoiding recurrence.
Simple steps can make a big difference:
Keep feet clean and dry, especially between the toes
Wear breathable shoes and change socks daily
Avoid walking barefoot in communal areas
Trim nails regularly and correctly
Rotate footwear to allow shoes to dry out fully
If you are prone to fungal infections, regular professional foot care can help keep nails healthy and reduce the risk of reinfection.
When to seek professional help
It’s worth seeing a podiatrist if:
The nail becomes thick, discoloured, or difficult to cut
The infection spreads to other nails
There is pain or discomfort when walking
Home treatments are not working
Early treatment is always more effective and can prevent long-term damage to the nail.
