In this article, we’ll explore the common causes and symptoms of yellow nails, as well as what you can do to prevent and treat them.

Causes of Yellow Nails

Yellow nails can be caused by a variety of factors, ranging from fungal infections to lifestyle habits. Here are some of the most common causes:

Fungal Infection

One of the primary causes of yellow nails is a fungal infection. This can occur when fungi enter the nail bed and start to grow. The result is a yellow or brown discoloration of the nail, as well as thickening and brittleness. Fungal infections are more common in toenails than fingernails, and they can be difficult to treat.


Another common cause of yellow nails is smoking. The nicotine and tar in cigarettes can stain your nails yellow over time, as well as your teeth and skin. If you’re a smoker, quitting can help improve the appearance of your nails, as well as your overall health.
