A fungal toenail is more than a cosmetic nuisance. Nails become thickened, discoloured and brittle, and the infection rarely clears on its own, spreading slowly to other nails if it is left. The good news is that it responds far better to treatment when it is caught early. Here is what causes fungal nails and what can be done.
What Causes a Fungal Toenail Infection?
Fungal nail infections are caused by the same kinds of fungi that cause athlete's foot, which thrive in warm, damp conditions. They often take hold after a nail injury, alongside athlete's foot, or where feet are regularly enclosed in warm shoes. Anyone can get them, and they become more common with age.
How to Spot a Fungal Nail Early
The earlier a fungal nail is treated, the easier it is to manage. Look out for:
- Thickening of the nail
- White, yellow or brown discolouration
- A brittle or crumbly nail edge
- The nail lifting away from the nail bed
- Discomfort or pressure in shoes
If you notice these, it is worth having the nail checked rather than assuming it will settle.
How Fungal Toenails Are Treated
Treatment depends on how much of the nail is involved and how long it has been present. It commonly includes reducing and thinning the affected nail to relieve pressure, topical treatment, and advice on hygiene and footwear to prevent reinfection. As part of our foot care service, a podiatrist assesses the nail and recommends the approach most likely to help in your case.
How to Prevent Fungal Nails Coming Back
Prevention matters as much as treatment. Keep feet clean and dry, dry carefully between the toes, change socks regularly, avoid sharing towels and nail tools, and let shoes air between wears. Treating athlete's foot promptly reduces the risk too, since the same fungus is often responsible.
At Advanced Footcare Group we assess and manage fungal nails and give clear advice on keeping them from returning.

Frequently asked questions.
Will a fungal toenail clear up on its own?
It usually will not. A fungal nail infection tends to persist and can slowly spread to other nails if it is left. The earlier it is assessed and treated, the more straightforward it is to manage, so it is worth having it looked at rather than waiting.
How do you treat a fungal toenail?
Treatment depends on how much of the nail is affected and how long it has been there. It can involve reducing and thinning the nail, topical treatments, and advice on footwear and hygiene to prevent reinfection. A podiatrist will assess the nail and recommend the most suitable approach for your situation.
How can I stop fungal nails coming back?
Keep feet clean and dry, dry carefully between the toes, change socks regularly, avoid sharing towels or nail tools, and let shoes air between wears. Treating any athlete's foot promptly also helps, since the same fungus is often involved.
