Fungal Nails
Fungal nails, or onychomycosis, are a common infection affecting the toenails or fingernails. They often begin as a white or yellow discolouration beneath the nail and can progress to thickening, brittleness, and distortion.
The condition is usually caused by dermatophyte fungi, thriving in warm, moist environments such as sweaty footwear or communal areas. It is more common in individuals with diabetes, reduced circulation, or weakened immunity.
While not always painful initially, it can become uncomfortable and affect nail appearance over time. Treatment requires consistency and may include topical or oral antifungals, with results developing gradually as the nail grows.
What causes fungal nails?
Discover what causes this condition and how it can it can impact you.
Fungal Exposure
Fungal nail infections are caused by organisms such as dermatophytes, yeasts, and moulds that invade the nail through small cracks or damage.
Warm, Moist Environments
Conditions such as sweaty footwear, communal showers, and swimming pools create the ideal environment for fungal growth and spread.
Nail Damage
Injury or repeated trauma to the nail can weaken its structure, making it easier for fungi to enter and establish infection.
Poor Circulation
Reduced blood flow, particularly in the feet, can limit the body’s ability to fight infection and support healthy nail growth.
Medical Conditions
Conditions such as diabetes or a weakened immune system increase susceptibility to fungal infections and can make them more persistent.
Hygiene and Footwear
Tight, occlusive footwear and inadequate foot hygiene can trap moisture, encouraging fungal development and recurrence.
Ageing
As nails grow more slowly and become thicker with age, they are more prone to infection and harder to clear once affected.
