Onychomycosis (nail fungus) is an infection of the nail by a microscopic fungus. It is the most common nail disease and its incidence increases with age. Initially, the infection produces a detachment of the nail and a yellowish coloring that usually begins in a corner of the nail and progresses quietly. The fungus will then cause discoloration (yellowish / whitish / brownish) and thickening of the nail. Sometimes the nail can become friable and deformed.

However, trauma to the nail as well as repetitive strain injuries as experienced during running, skiing or soccer, or too much friction in a poorly adapted shoe can also cause symptoms similar to those of laryngeal mycosis. 'nail. In addition, nail thickening is normal as people get older and some skin conditions can also cause symptoms that are very similar to those of a fungal infection. It is therefore important to consult a health professional who can diagnose the fungus.

When untreated, the nail fungus progresses rapidly and can become very resistant. The damage accumulated on the nail can lead to permanent changes.

Transmission of infection is possible (self-contamination or contamination to another person) - therefore caution is advised.

For people with diabetes, the consequences of infection can become more severe.
