Fungal nail infections are one of the most common issues podiatrists treat, yet they’re often ignored in the early stages. What begins as a slight change in colour or texture can progress into thickened, brittle nails that are difficult to manage. While sometimes seen as just a cosmetic concern, fungal nails can become uncomfortable, spread to other nails, and affect your confidence.
What Is a Fungal Nail Infection?
A fungal nail infection, also called onychomycosis, happens when fungi enter the nail through small cracks or openings. Once inside, the infection can change the nail’s appearance, texture, and health. Toenails are most commonly affected, as shoes and socks create the warm, moist environment fungi love.
Signs of a Fungal Nail Infection
The infection can show up in different ways. Nails may turn yellow, white, or even brown. They might become thicker, more brittle, or start to crumble. Some people notice a persistent odour, or find the nail beginning to lift away from the nail bed.
What Causes Fungal Nails?
There isn’t always a single cause. Sometimes it’s the result of walking barefoot in communal areas like pools or gyms. For others, nail trauma, such as stubbing a toe, can give fungi a way in. Wearing tight or non-breathable shoes, having persistently sweaty feet, or conditions like athlete’s foot can also make fungal nails more likely. People with diabetes or reduced immunity are particularly at risk.
Preventing Fungal Nails
The good news is that small daily habits make a big difference. Keeping feet clean and dry, changing socks regularly, and wearing breathable footwear all help reduce risk. It’s also worth avoiding the sharing of nail clippers or shoes, and wearing thongs in public showers or pool areas to limit exposure.
When to See a Podiatrist
If you notice changes in the colour, shape, or thickness of your toenails, it’s best to have them checked. Fungal infections rarely clear on their own, and the longer they are left untreated, the harder they can be to manage.
A podiatrist can confirm whether the changes are fungal or caused by another condition, and guide you through safe, effective treatment options. They can also help reduce nail thickness, manage discomfort, and provide advice to stop the infection coming back.
