Early Signs of Toenail Fungus and What Causes Them
Toenail fungus, also known as Onychomycosis or Tinea Unguium, often begins with subtle changes such as yellowing, thickening, or brittleness of the nails. This condition is commonly caused by fungi like Trichophyton rubrum and Trichophyton interdigitale, which thrive in warm, moist environments. It tends to affect the big or little toenails and becomes more common with age or following other fungal infections like athlete’s foot (Tinea Pedis).
Early symptoms may seem mild but can worsen over time if left untreated, potentially leading to discomfort and complications. Recognising the causes and early signs of toenail fungus is important for effective management and prevention of further spread. Understanding these factors helps you take timely action to protect your foot health and maintain strong, healthy nails.
What are the Common Causes of Fungal Toenail?
Toenail fungus often starts small but can become more troublesome if conditions favour its growth. Several factors increase the likelihood of infection, making it easier for the fungus to thrive and spread.
Below are some of the most common causes linked to fungal toenails:
- Warm and Damp Environments
- Poor Foot Hygiene & Excessive Sweat
- Wet Weather Season
- Nail Trauma
- Athlete’s Foot
- Weakened Immune System
What is a Fungal Toenail?
A fungal toenail is also known as onychomycosis. It is a common condition where the toenail becomes infected by fungi, typically dermatophytes. This infection usually begins when fungi enter the nail through small cracks or breaks in the skin around the nail, especially in warm, moist environments. Over time, the affected nail may become discoloured (often yellow, white, or brown), thickened, brittle, and crumbly. In some cases, the nail can distort in shape or lift away from the nail bed.
While it may seem like a cosmetic issue at first, fungal toenail infections can worsen if left untreated, spreading to other nails and causing discomfort or pain. For individuals with diabetes or poor circulation, the condition can lead to more serious complications. East Coast Podiatry emphasises early diagnosis and treatment using methods such as nail debridement, topical or oral antifungals, and advanced options like photodynamic antimicrobial therapy (PACT) to effectively manage and eliminate the infection.

Methods to Relieve Discomfort and Promote Well-being
Depending on the severity of the infection, different approaches can be used. Below are some available options:
Toenail Debridement
This procedure involves carefully thinning the thickened toenail to enhance the effectiveness of other treatments. It is often performed alongside other care methods to improve outcomes.
Special Light Therapy
Known as Photodynamic Antimicrobial Therapy (PACT), this treatment uses a special photosensitising gel combined with light to specifically target and reduce fungal infection in the nails.
Toenail Removal
For severe or persistent infections, removing the affected toenail through a minor procedure under local anaesthesia may be recommended. This allows a healthy new nail to grow in its place, supporting long-term recovery.
What are the Common Symptoms of Fungal Toenail?
Understanding the Signs for Early Detection
Fungal toenail infections can cause noticeable changes to the appearance and texture of your nails. Recognising these symptoms early is important for effective treatment and preventing the infection from worsening or spreading.
Common signs include:
- Discolouration - Nails may turn yellow, brown, or white as the infection develops.
- Thickening of the Nail - Infected nails often become thicker and harder than usual.
- Brittle or Crumbly Nails - Nails may become fragile, breaking or crumbling easily.
- Distorted Nail Shape - The natural shape of the nail can become irregular or misshapen.
- Separation from the Nail Bed - The nail may lift or detach from the skin underneath.
- Foul Odour - A noticeable unpleasant smell can sometimes be present.

NewGreat experience at East Coast Podiatry (Orchard)! Had a persistent nail fungus issue over the last couple of years and it was solved so quickly and efficiently with the team. My podiatrist - Ms Peggy explained and assessed my condition in great detail, and recommended me the follow up actions required to get the issue all treated. Was an overall superb and pleasant treatment experience 🙂

We have been with Gerorgina for my daughter in-toes and flat foot issue. Gone through a thorough treatment, exercises, feet braces and we can see massive improvement in my daughter's posture and feet.
Georgina and the staff have been very helpful and making every visit smooth and pleasant. Keep up the good work!

Our 6-year-old son had very severe in-toeing when we first visited Dr. Michael in October 2024. We’re incredibly thankful for his expertise—after just 8 months of treatment, our son is now very close to having an ideal foot structure.
What we appreciated most was the all-in-one pricing—it covered everything from braces to follow-ups, making the treatment both convenient and great value for money. The clinic’s location in Orchard is also a big plus for accessibility. Highly recommend Dr. Michael, especially for concerned parents dealing with pediatric foot issues!
