Toenail fungus is an infection that gets in through cracks in your nail or cuts in your skin. It can make your toenail change colour or get thicker.


Nail fungus, also known as onychomycosis is a common condition that begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, nail fungus may cause your nail to discolour, thicken and crumble at the edge.

Fungi thrive in moist, warm environments and when given these ideal conditions, they can naturally overpopulate. This is often characterised as fungal infections such as jock itch, athlete’s foot and ringworm. The same fungus which causes these infections can then continue to cause nail infections. When the fungi overgrows in, under, or on the nail, you will suffer from a fungal nail infection.

Fungal nail infections can also be caused by walking barefoot in places where they can be spread easily such as communal showers, changing rooms and gyms or from damage to your nails from sports injuries and the like.

It is notoriously difficult to treat. Traditional treatments with medication and topical creams have limited success.

When left untreated, they can not only look unpleasant, but also spread to other nails causing further issues.
