Are your nails turning yellow, thick, or starting to crumble? While it might seem like a small issue, these could be the early signs of a fungal nail infection. What may start as a tiny spot can quickly spread, leaving your nails brittle, damaged, and unhealthy. Catching it early is key—treat it now and get your nails back to looking strong and healthy!

What Is Nail Fungus (onychomycosis)? 

Nail fungus, medically known as onychomycosis, is a common fungal infection that affects the fingernails or toenails. It typically begins as a small white or yellow-brown spot beneath the tip of the nail. If left untreated, the infection can spread deeper, leading to discoloration, thickening, and crumbling at the edges of the nail.   

Common Symptoms of a Fungal Nail Infection

Paying attention to subtle changes in your nails’ appearance, texture, or smell can help detect the infection before it becomes severe.

The affected nail appears thickened, discolored, and brittle, with a yellowish-brown hue and rough texture. The surrounding nails look relatively healthy. Keywords: Fungal Nail, Fingernail Infection, Onychomycosis, Nail Health, Brittle Nails, Discolored Nails.

Here are some signs to watch for that may indicate a fungal nail infection:

  1. Discoloration: The nail may turn white, black, yellow or green, often one of the first signs of infection.

  2. Thickening: The nail may become thicker than usual, making it harder to trim and maintain.

  3. Brittleness: Infected nails often become brittle, crumbling or breaking easily. 

  4. Separation from the Nail Bed: The nail may detach from the underlying skin, creating a gap between the nail and nail bed.

  5. Foul Odour: A foul smell may develop from the infected nail.

  6. Redness and Swelling: The skin around the nail may become red, sore, or swollen.

Common Causes Of Nail Fungus

Each cause is represented by a red circular icon with an illustration: (1) A heart with a medical cross symbol labeled 'Underlying Health Conditions,' (2) A bleeding fingernail labeled 'Nail Injuries,' (3) A group of people with a warning sign labeled 'Environmental Exposure,' and (4) A pair of brown shoes with lightning symbols labeled 'Non-Breathable Shoes.' Keywords: Nail Health, Fungal Nail Causes, Nail Injuries, Footwear Issues, Environmental Risk, Underlying Conditions.
  • Underlying health conditions: Conditions such as diabetes, high blood pressure, or a weakened immune system can increase the risk of infection. 

  • Nail injuries: Minor skin or nail injuries can provide an entry point for fungi.

  • Environmental exposure: Walking barefoot in damp public areas like swimming pools, communal showers, or gyms can increase exposure to fungi.

  • Wearing tight and non-breathable shoes: Shoes that cause excessive foot sweating create a warm and moist environment that promotes fungal growth.

Fungal Nail Infection Treatment Options

  1. Antifungal Medication
    Antifungal nail creams are applied directly to the affected nail. These are often used for milder cases or in combination with oral medication.

  2. Nail Removal
    In severe infections, removing the affected nail may be necessary. This procedure exposes the nail bed, allowing targeted antifungal treatment and promoting the growth of a healthy new nail. 

  3. Treatment by Podiatrist
    Personalised debridement and advanced light therapy are used to manage infections, enhance nail health, and prevent the spread of the fungus. 

💡Tips to Prevent Fungal Infection

  • Wear Appropriate Footwear: Choose shoes made of breathable material and avoid tight-fitting footwear.

  • Maintain Foot Hygiene: Keep your feet clean and thoroughly dry, especially between the toes.

  • Avoid Walking Barefoot in Public Areas: Always wear sandals or flip-flops in communal showers, pools, and gyms to avoid exposure to fungi.

  • Seek Treatment Early: If you have bruised your nail, or suspect fungal infection, it is best to seek treatment by a podiatrist as soon as possible to prevent further infection.

FAQs on Nail Fungus

1. How long does it take to treat nail fungus?
Treatment duration depends on the severity of the infection. During your podiatry appointment, the podiatrist will trim and thin the nails to remove infected areas, allowing antifungal treatments to work more effectively. The therapy typically takes at least 3 months but may require longer for severe infections. Consistency in treatment and proper foot care are key to achieving the best results.

2. What happens if you leave nail fungus untreated?
Leaving toenail fungus untreated can lead to several complications, including the spread of infection to other toenails, surrounding skin, or even fingernails. Over time, the affected nail may become thick, brittle, and misshapen, leading to discomfort and difficulty wearing shoes or walking. Early treatment is essential to prevent these complications and maintain healthy nails.

3. When should I start seeing a Podiatrist?
If you notice discoloration, thickening, or deformity in your toenails, it’s best to consult a podiatrist promptly. Early intervention can prevent the infection from worsening and spreading to other nails or surrounding skin. Attempting home treatments may not always be effective, and delaying professional care could lead to more severe complications.
