Noticed a toenail becoming thicker, discoloured, crumbly or harder to trim? These changes can be easy to brush off at first, especially when they do not cause pain straight away.
Fungal nail infections often develop gradually, which means many people wait until the nail has changed significantly before having it checked. While the concern may seem cosmetic at first, fungal nails can become uncomfortable, spread to other nails and become more difficult to manage over time.
The earlier a fungal nail concern is assessed, the easier it can be to understand what is causing the change and what treatment options may be suitable.
What Is a Fungal Nail Infection?
A fungal nail infection occurs when fungus affects the toenail. This can cause the nail to change in colour, texture, shape or thickness.
Toenails are often more commonly affected than fingernails because feet spend a lot of time in warm, enclosed shoes. This can create an environment where fungus is more likely to grow, especially when moisture is present.
A fungal nail infection can affect one nail or several nails. It may start subtly with a small patch of discolouration or a slight change in texture, then become more noticeable over time.
What Does a Fungal Nail Look Like?
Fungal nails can look different from person to person. Some changes may be mild at first, while others can become more obvious.
Common signs may include:
- Yellow, white or brown discolouration
- Thickened toenails
- Brittle or crumbly nail edges
- Nail lifting from the nail bed
- A change in nail shape
- Build-up under the nail
- A dull or rough nail surface
- Difficulty trimming the nail
- Discomfort when wearing shoes
Not every discoloured or thickened nail is fungal, which is why it can be helpful to have the nail assessed by a podiatrist. Nail trauma, pressure from footwear, skin conditions and other causes can sometimes create similar changes.
Why Do Fungal Nail Infections Happen?
Fungal nail infections can develop for a range of reasons. They are often linked to moisture, footwear, trauma to the nail or exposure to fungus in shared environments.
Common contributing factors may include:
- Warm, enclosed footwear
- Sweaty feet
- Repeated nail trauma
- Walking barefoot in shared wet areas
- Previous tinea or fungal skin infection
- Reduced nail health
- Older age
- Difficulty drying between the toes
- Reduced circulation or certain health conditions
For some people, the infection may begin after the nail has been damaged. Even small trauma from tight shoes, sport or repeated pressure can create changes in the nail that make it easier for fungus to enter.
Are Fungal Nails Just Cosmetic?
Fungal nails are often dismissed as a cosmetic concern, but they can affect more than the appearance of the nail.
As the nail thickens or changes shape, it may become uncomfortable in shoes. The nail can become harder to trim, more prone to crumbling and more likely to place pressure on the surrounding skin.
In some cases, fungal nail infections can also spread to other nails or be linked with fungal skin infections such as tinea.
While some cases are mild, ongoing nail changes should not be ignored, especially if the nail is becoming thicker, painful, difficult to trim or uncomfortable in footwear.
Can Fungal Nails Go Away on Their Own?
Fungal nail infections do not always clear on their own. In many cases, they can slowly worsen if the underlying infection is not addressed.
Because toenails grow slowly, fungal nail treatment can take time. This is one reason early assessment is helpful. The sooner the concern is identified, the sooner the right management approach can begin.
It is also important to understand that not every nail change is caused by fungus. Guessing the cause may lead to the wrong treatment, especially if the nail change is actually due to pressure, trauma or another skin or nail condition.
When Should You See a Podiatrist?
It may be time to see a podiatrist if you notice ongoing changes to the colour, thickness or texture of your toenails.
You should also consider an assessment if:
- The nail is becoming thicker
- The nail is painful in shoes
- The nail is difficult to trim
- The nail is lifting or crumbling
- More than one nail is changing
- You have recurring tinea
- The skin around the nail is becoming irritated
- You are unsure whether the nail change is fungal
- You have diabetes or circulation concerns
A podiatrist can assess the nail and help determine what may be causing the change. This can provide clarity and help guide the most appropriate next steps.
How Can a Podiatrist Help With Fungal Nails?
A podiatrist can assess the toenails, surrounding skin and overall foot health to help identify whether a fungal infection may be present.
Depending on the nail and symptoms, podiatry care may include:
- Assessment of the affected nail
- Reduction of thickened nail where appropriate
- Advice on antifungal treatment options
- Footwear and hygiene advice
- Guidance around reducing reinfection
- Monitoring nail changes over time
- Support with trimming difficult nails
For thicker nails, professional reduction can also help relieve pressure and make the nail easier to manage. This may make footwear more comfortable and help reduce irritation around the nail.
The most suitable approach will depend on the severity of the infection, how many nails are affected and whether there are any other foot health concerns present.
How Can You Reduce the Risk of Fungal Nails?
While fungal nail infections cannot always be prevented, there are steps that may help reduce the risk.
These include:
- Keeping feet clean and dry
- Drying well between the toes
- Changing socks regularly
- Wearing breathable footwear where possible
- Avoiding walking barefoot in shared wet areas
- Treating tinea early
- Not sharing nail clippers or footwear
- Allowing shoes to dry between wears
- Checking nails regularly for changes
Foot hygiene and shoe care can play an important role, especially for people who are prone to sweaty feet, tinea or repeated nail concerns.
Why Early Treatment Matters
Fungal nail infections can become harder to manage as the nail becomes thicker or more affected.
Early assessment can help confirm what is happening and reduce the chance of the issue progressing. It can also help rule out other causes of nail changes, such as trauma, pressure from shoes or skin conditions.
If you have noticed a nail starting to change, it is better to have it checked early rather than waiting until it becomes painful, difficult to trim or uncomfortable in shoes.
