Fungal infections are commonly associated with the feet, thriving in warm and damp environments. However, fungi can affect various parts of the body, including the armpits, groin, soles of the feet, and even the mouth and lungs.

Nail infections, particularly on the toenails, are common due to the enclosed nature of feet in shoes, creating an ideal environment for fungal growth. This condition is known as Onychomycosis and is characterized by fungal and discolored toenails.

​

Addressing Onychomycosis involves considering three key aspects:

​

1. Environmental Changes: Creating an environment less conducive to fungal growth is crucial. This includes using antiperspirants, practicing good hygiene, and following footwear advice to prevent recurrence.

2. Fungus Destruction: Medications such as terbinafine, itraconazole, and amorolfine have proven scientific efficacy in treating fungal infections. The choice of medication depends on the extent and location of the infection.

3. Targeted Delivery: Ensuring that the antifungal treatment reaches the specific affected area is vital for effectiveness. The success of treatment often depends on the chosen delivery method.

​

There are various treatment options, each with its considerations:

​

• Oral Treatment (Tablets): Terbinafine and itraconazole tablets can be taken internally to reach the nail matrix. However, this option carries some risks and should be considered in consultation with a Podiatrist or GP.

​

• Toenail Removal: Complete removal of the nail, coupled with the destruction of the nail matrix, prevents regrowth and subsequent fungal infection. Surgical or chemical removal, such as with 40% urea cream, is possible.

​

• Toenail Fenestration: Drilling small holes in the nail plate allows topical antifungal agents to reach the nail bed. This method is suitable for distal onychomycosis but requires caution to avoid nail bed damage.

​

• Toenail Debridement: Removing as much fungal nail as possible enhances the effectiveness of topical antifungal agents. Podiatrists can perform debridement using filing, drilling, or "shaving" the nail plate.

​

• Photodynamic Therapy: Light-based treatments like PACT or laser therapy have the potential to destroy fungal cells, but success may require repeated treatments.

​

It's important to note that the suitability of certain treatments or delivery methods depends on individual medical conditions. Seeking professional advice, such as consulting a Podiatrist, is essential to determine the most suitable approach for your specific situation.
