Why Is My Big Toe Nail Yellow?

Are you concerned about the yellow discoloration of your big toe nail? It’s a common problem and can occur due to various reasons. In this article, we’ll explore why your big toe nail might be turning yellow and what you can do about it.

Causes of Yellow Big Toe Nails

Yellow big toe nails can be caused by several factors. Here are some of the most common causes:

Fungal Infection

One of the most common causes of yellow big toe nails is a fungal infection. Fungal infections can occur due to poor hygiene or wearing tight-fitting shoes that create a warm and moist environment for the fungus to thrive. If left untreated, the fungal infection can spread to other toenails and even the skin.

Trauma or Injury

Trauma or injury to the big toe can also cause yellow discoloration of the nail. This can happen due to repeated hitting of the toe against a hard surface or wearing tight shoes that put pressure on the nail bed. The trauma can cause the nail to separate from the nail bed, leading to a yellowish discoloration.
