Fungal nails, or in medical terminology, Onychomycosis, is a common condition that can affect both the fingernails and toenails, but is more often seen in toenails. In fact, around 10% of Australians experience fungal toenails in their lifetime. Typically, fungal toenails do not cause great harm but are cosmetically unsightly. They can appear white, yellowish or various shades of brown and can have a slight odour. With sandal seasons approaching, the last thing you want to do is cover your toes!

Fungal infections come from the same germs that cause tinea of the skin. The fungi (or dermatophytes) are parasites that feed off the nail (made up of the protein keratin). The process isn’t dissimilar to the way termites can invade timber in a home. The infestation of fungi in the nail eventually weakens the nail and causes it to split and become brittle.

Fungal toenail infections can quickly spread to other nails and your skin. It can lead to other nail pathologies including ingrowing nails and secondary bacterial infections.

Stages of fungal toenails: 

Stage 1: White Superficial Onychomycosis (WSO): Mild fungal infection of the nail plate. Delineated ‘white islands’ or streaks on the surface of the nail. The nail becomes rough, friable and brittle with cross-infection of the skin and adjacent nails.

Stage 2: Distal Subungual Onychomycosis (DSO):Dermatophytes invade and penetrate the nail plate and infect under the surface of the nail and the nail bed itself. The nail appears lifted and opaque with yellow to brown colour changes. Thickening and pain may be experienced.

Stage 3: Complete Subungual Onychomycosis (CSO):Complete invasion and penetration of the nail plate, under the surface of the nail and the nail bed itself. Nail appears lifted and detached with yellow, green to brown colour changes. Localised thickening if often present and pain can be experienced. Infection of adjacent nails is likely.

Stage 4: Total Dystrophic Onychomycosis (TDO):Infection results in damage to the nail, causing a distinctly fibrous, crumbling and thickened nail. Nail appears thickened and friable with yellow, green to brown colour changes. Nail appears to grow very slowly or not at all. Infections often present in several nails.

If you are experiencing the above symptoms, the best thing to do is to see your local Podiatrist for an assessment and treatment plan. A common mistake many women make is covering their infection with nail polish, which can only aggravate the condition and create an even better environment for the fungus to continue to grow. Understanding the causes of fungal nails can help prevent the spread and recurrence of infection.
