What is a Fungus Nail Infection?

Fungal nail infection, medically termed Onychomycosis, is a common condition that occurs when fungi (dermatophytes, yeasts, or moulds) invade the toenail unit – the nail plate, nail bed, or root. This invasion often leads to changes in the nail’s appearance, such as discoloration, thickening, and crumbling.

Symptoms of a Fungus Nail Infection

Recognising the Signs of Toenail Fungus

Fungal nail infections usually develop slowly — but the longer you wait, the harder they are to treat.

Common symptoms include:

  • Yellow, white, brown, or black nail discolouration

    The nail may lose its clarity and develop uneven or patchy colours, often spreading across the surface.

  • Thickened nails that are tough to trim

    Affected nails can become bulky, making it difficult to cut them using regular clippers.

  • Brittle or crumbly nail edges

    Pieces of the nail may break off easily, especially near the tips or sides.

  • Misshapen or lifting nails (a sign of onycholysis)

    The nail may start separating from the nail bed, causing a lifted appearance.

  • Build-up of debris under the nail

    A chalky or powdery substance may collect beneath the nail, sometimes making shoes feel tighter.

  • Unpleasant smell from the affected nail

    Odour may develop due to trapped moisture and debris, especially in enclosed footwear.

  • Mild discomfort or pressure when wearing shoes

    As the nail thickens, it can press against the shoe, leading to soreness or irritation.

What Causes Nail Fungus?

What Causes Nail Fungus?

Nail fungus is caused by dermatophytes, yeasts, or moulds that thrive in warm, moist environments. These fungi enter the nail through tiny cracks or skin breaks. Common causes include:

  • Singapore’s Humid Climate
  • Sweaty or poorly ventilated footwear
  • Walking barefoot in public spaces (like pools, showers, gyms)
  • Nail trauma or injury
  • Cross-contamination from shared or unsanitised nail tools
  • Athlete’s foot (Fungal skin infection of the foot) spreading to the toenails

Are You at Risk of Getting a Fungus Nail Infection?

Are You At A Higher Risk?

Certain factors make fungal nail infections more likely:

    • Ageing (more common in those over 50)

      Nail growth slows with age, and changes in circulation make infections more likely.

    • Diabetes or poor circulation

      Reduced blood flow to the feet can affect nail health and delay healing.

    • Weakened immune system

      A lowered immune response may make it harder for the body to manage fungal infections.

    • Excessive sweating (hyperhidrosis)

      Constant moisture creates a welcoming environment for fungi to thrive.

    • Tight, enclosed shoes worn for long hours

      Shoes that trap heat and sweat increase the risk of developing or worsening infections.

Frequently Asked Questions About Our Fungus Nail Treatment

Fungal nail infections can be stubborn and slow to clear. Here are some answers to questions many patients ask before starting treatment.

The best approach depends on the severity observed during clinical assessment, patient health, and preferences, determined after consultation at Fine Podiatry Clinic. Our most popular treatment would be the PACT treatment where patients see 85% of improvement after 6-8 sessions

Yes. It can spread to other toenails, the skin (athlete's foot), or even fingernails. The fungi can spread from person to person through direct contact or, more commonly, indirect contact via contaminated surfaces (floors, clippers, shoes).

To remove the nail fungus completely, it takes time as a new, healthy nail grow out completely in approximately 6 months for toenails, sometimes longer. You may see improvement earlier, but completing the full treatment course is crucial.

It is best to avoid regular salons. Medical pedicures are safer and performed under sterile conditions by professionals.
