Fungal Toenails: Causes, Symptoms & Treatment

Fungal Toenail Treatment For Thickened, Discoloured & Damaged Nails

Fungal toenails are one of the most common nail conditions we see at Callen Olive.

Many people feel embarrassed by the appearance of their nails and may avoid open-toed footwear, holidays, swimming pools or even showing their feet to family and friends. Others experience discomfort, difficulty cutting their nails or pain when wearing footwear. In some cases, nails become so thickened and distorted that they begin to affect comfort, confidence and day-to-day activities.

Many people also assume that thickened, discoloured nails are simply part of ageing or old nail damage. Others believe fungal nails are purely cosmetic and not worth addressing.

In reality, fungal nail infections rarely improve without treatment and often gradually worsen over time. They can spread to neighbouring nails, become increasingly thick and difficult to manage and may even contribute to recurring fungal skin infections.

The good news is that many fungal nail infections can be successfully managed with the right diagnosis and treatment plan.

At Callen Olive, we've been helping people manage fungal nail infections for many years. We understand that successful treatment is about more than simply improving the appearance of the nail. It's about helping people feel comfortable, confident and supported throughout their journey towards healthier nails.

You're Not Alone

Fungal toenails are one of the most common conditions we manage in clinic.

Our experienced podiatrists regularly assess and treat fungal nail infections ranging from mild changes affecting a single nail to more advanced infections involving multiple nails.

Many people come to us feeling frustrated, embarrassed or simply unsure whether their nails are even fungal. Others have tried over-the-counter products without success or have accepted their nails as something they simply have to live with.

You are not alone.

Whether your goal is improving the appearance of your nails, making them easier to manage or addressing discomfort, we're here to help you understand your condition, explore your options and support you throughout every stage of your journey towards healthier nails.

What Is A Fungal Toenail Infection?

A fungal nail infection occurs when microscopic fungi invade the nail plate or the skin beneath the nail.

Over time, the infection may cause the nail to become:

  • Thickened

  • Yellow, white or brown in colour

  • Brittle and crumbly

  • Distorted in shape

  • Lifted away from the nail bed

  • Difficult to cut and maintain

The infection may affect one nail or several nails and can gradually worsen if left untreated.

Are All Thickened Or Discoloured Nails Fungal?

No.

Not all thickened, discoloured or damaged nails are caused by fungal infection.

Trauma, repetitive pressure from footwear, psoriasis, eczema, ageing and other nail conditions can all cause changes that look very similar to fungal nails.

Accurate diagnosis is important because treating a nail as fungal when it is not can lead to unnecessary expense, frustration and disappointment.

Understanding the cause of your nail changes is often the first step towards achieving healthier nails.

What Causes Fungal Toenails?

Fungal nail infections are caused by organisms that thrive in warm, dark and moist environments.

Common risk factors include:

  • Athlete's Foot

  • Sweaty feet

  • Damage or trauma to the nail

  • Communal changing rooms and swimming pools

  • Increasing age

  • Diabetes

  • Reduced circulation

  • Certain medical conditions affecting the immune system

Many infections begin after a small injury to the nail that allows fungal organisms to enter.

Will A Fungal Toenail Go Away On Its Own?

Unfortunately, fungal nail infections rarely resolve without treatment.

In many cases, the infection slowly spreads through the nail, causing increasing thickening, discolouration and nail damage over time.

Early assessment and treatment often provide the best opportunity for successful outcomes.

Why Early Treatment Matters

Many people assume fungal nails are simply a cosmetic concern.

However, untreated fungal nail infections may:

  • Continue to spread

  • Affect neighbouring nails

  • Increase nail thickening

  • Cause discomfort in footwear

  • Become increasingly difficult to cut and manage

  • Become more difficult to treat

  • Act as a source of recurring fungal skin infections

The earlier treatment begins, the easier it is often to achieve improvement.

Athlete's Foot & Fungal Toenails

Fungal skin infections and fungal nail infections are closely linked.

The same fungal organisms that infect the skin can sometimes spread into the nails. Likewise, fungal nails can act as a reservoir for reinfection, contributing to recurring Athlete's Foot.

Addressing both conditions together often forms an important part of long-term management and may help support better outcomes.

How We Assess Fungal Toenails

Accurate diagnosis is essential because not all thickened or discoloured nails are fungal.

Assessment may include:

  • Clinical examination

  • Review of symptoms and nail history

  • Assessment of nail damage

  • Discussion of treatment options

In some cases, laboratory testing may be recommended to help confirm the diagnosis.

By understanding the cause of the nail changes, we can help you make informed decisions about the most appropriate treatment pathway for your individual circumstances.

Your Personalised Treatment Options

Not every fungal nail requires the same treatment approach.

Following your assessment, your podiatrist will discuss the most appropriate treatment options based on the number of nails affected, the severity of the infection, your medical history and your personal goals.

Treatment may include:

  • Lunula Laser treatment

  • Professional nail reduction and ongoing management

  • Home care and prevention strategies

  • Management of associated Athlete's Foot

  • Nail surgery in carefully selected cases

For some people, fungal nails become extremely thickened, distorted, uncomfortable or increasingly difficult to manage. In these circumstances, permanent nail removal surgery may be discussed as a treatment option.

Whilst nail surgery does not treat the fungal infection itself, it can provide a permanent solution for people living with painful, problematic or persistently damaged nails that are affecting comfort, confidence or quality of life.

Your clinician will take the time to explain the benefits and considerations of each treatment option and help you choose the approach that is most appropriate for your individual circumstances.

Lunula Laser Treatment For Fungal Toenails

At Callen Olive, we offer Lunula Laser, an advanced, non-invasive treatment option for fungal nail infections.

Unlike traditional laser treatments that generate heat, Lunula Laser uses low-level laser energy designed to target fungal infections without pain or discomfort.

Benefits include:

  • No pain

  • No needles

  • No anaesthetic

  • No downtime

  • Suitable for most patients

  • Quick treatment sessions

Clinical studies have demonstrated success rates of approximately 86%, making Lunula Laser one of the most exciting treatment options currently available.

Why Do Fungal Nails Take So Long To Improve?

One of the most important things to understand is that nails grow slowly.

Even when treatment is successful, improvement is gradual because the damaged part of the nail cannot simply disappear overnight. Improvement occurs as healthy new nail gradually grows from the base of the nail and replaces the damaged nail over time.

Toenails typically grow only 1-1.5mm per month, meaning visible improvement can take several months and, in some cases, more than a year.

Patience is essential, but many people begin to notice healthier nail growth as the nail gradually grows out.

Understanding this process helps set realistic expectations and is an important part of achieving successful outcomes.

Home Care & Preventing Reinfection

Successful treatment involves more than treating the nail alone.

We may recommend:

  • Treating Athlete's Foot if present

  • Regular shoe hygiene

  • Antifungal footwear sprays

  • Good foot hygiene

  • Changing socks daily

  • Breathable footwear

  • Appropriate nail care

These measures help reduce the risk of reinfection and support long-term results.
