What causes thick toenails?

If you have a green toenail, it may start to thicken. There are several causes for the appearance of thick toenails. Today, the nail supply expert Maryton will discuss the most common causes of the appearance of thick toenails.

A fungal infection

The most common cause of the appearance of thick toenails is onychomycosis. Onychomycosis most often develops in the toenails because it needs a warm, moist environment.

A nail injury

Thick toenails can appear as a result of sudden or repeated trauma or injury. Mostly it happens to sports people like footballers, runners and dancers. People who wear ill-fitting shoes are also prone to thick toenails.

Yellow nail syndrome

One of the less common causes of thick toenails is yellow nail syndrome. This disease causes the nails to turn yellow and become curved and hard. A person who suffers from yellow nail syndrome often has breathing problems and swelling in the arms and legs.

Psoriasis is an autoimmune disease that most often results in the appearance of red, scaly patches on the skin. Nail psoriasis often accompanies skin disease and affects both fingernails and toenails.


Toenails thicken with age because the body isn’t able to renew itself as much as at a younger age. This condition most often affects the nails of the feet but can in some cases affect those of the hands as well.
