Fungal Nails

Fungal nails — known medically as onychomycosis — are a nail infection caused by fungi that invade the nail and the skin beneath it, leading to discolouration, thickening and crumbling. It's a common and often persistent condition, but with accurate diagnosis and a consistent treatment plan, it can be managed.

At Blueprint Podiatry in Tuggerah, our podiatry team understands how frustrating fungal nails can be — and how easily they're mistaken for other nail problems. We take the time to assess your nails properly and tailor a plan to your situation.

What causes fungal nails?

Onychomycosis is most often caused by dermatophyte fungi, though yeasts and moulds can also be involved [1]. These fungi thrive in warm, moist environments — think enclosed shoes and shared spaces like pool decks and change rooms. Risk factors can include increasing age, diabetes, reduced circulation, a history of athlete's foot (tinea), nail trauma and a weakened immune system [1][2].

How do I know if I have a fungal nail infection?

Fungal nails often show up with recognisable changes:

• Yellow, brown or white discolouration
• Thickened nails that are hard to trim
• Brittle, crumbly or flaky nail edges
• Lifting of the nail from the nail bed
• Sometimes a slight odour or debris under the nail

Because several conditions — including psoriasis, trauma and other nail disorders — can look very similar, accurate diagnosis matters. Confirming the diagnosis is an important first step before committing to treatment [2].

How does Blueprint Podiatry assess and treat fungal nails?

Our three registered podiatrists each hold a Bachelor of Podiatry, so assessment begins with a careful clinical examination of your nails, surrounding skin and contributing factors. Where helpful, we may use a Wood's lamp (UV) as an adjunct to screen the skin and nails. It's worth noting this supports rather than replaces clinical assessment, as not all organisms fluoresce.

Once we understand what we're dealing with, your management plan may include:

• Reducing and debriding thickened nails to relieve pressure and improve comfort
• Topical antifungal options and guidance on consistent application
• Education on footwear, foot hygiene and reducing reinfection risk
• Onward referral to your GP where an oral antifungal or further investigation may be appropriate

Because fungal nails can be slow to clear and prone to returning, we focus on realistic expectations and a plan you can stick to. We'll also check for related issues like tinea, ingrown nails or nail trauma, and our podiatrists offer nail surgery (partial nail avulsion) where it's clinically indicated.

When should I see a podiatrist about fungal nails?

It's worth booking in if your nails are changing colour or thickening, if trimming has become difficult, or if you have diabetes or reduced circulation — these conditions make any nail or skin problem more important to monitor. Early assessment also helps confirm whether it's actually a fungal infection or something else.
