Other Causes of Yellow Toenails

Apart from fungus, there may be other reasons why your toenails have that unhealthy yellow hue. Here’s a list of some of them.

  • Viruses – Growths under the nail caused by viruses – e.g. warts.
  • Trauma – E.g., hitting your toenail against shoes that are too small. (Severe trauma may even separate the toenail from the underlying skin tissue.)
  • Medications – Certain medications can change the color of your toenails.
  • Lymphedema (fluid retention and tissue swelling in the leg).
  • Circulation problems, a weakened immune system, or diabetes.
  • Yellow nail syndrome (YNS). This is discussed below.
  • Wearing toenail polish for too long. If you paint your toenails with a color involving yellow – think yellow, orange, or red, your nails may be stained yellow when you remove the polish.
  • Vitamin or nutritional deficiencies – To find out more, read this article from Podiatry Today.
  • Brittle or weak toenails.
  • Bacterial growth under the toenail.

Yellow Nail Syndrome (YNS)

YNS is, fortunately, a rare genetic disorder. The affected toenails will show a marked thickening and will be yellowish or greenish in color. Most patients will also suffer from pleural effusions (excess fluid surrounding the lungs and compromising breathing).

What Can My Podiatrist Tell me About my Yellow Toenails?

Your podiatrist can have a toenail biopsy performed. Don’t worry, it won’t hurt! A small piece of your toenail will be sent out to a lab for a PAS (Periodic Acid-Schif) stain. A PAS stain is a simple test that will help narrow down the reasons for your yellow toenails.

What’s the Best Treatment for Yellow Toenails?

  • If your nails are stained from polish, you simply have to wait for the nails to grow out.
  • If you have a fungal infection, your podiatrist will determine the proper treatment based on its severity and extent. You may be advised to use over the counter medication, a prescribed topical anti-fungal cream, a medicated polish, or an oral antifungal medication. Apply the medication as instructed and be patient. In extreme cases, surgical removal of the toenails may be necessary.
  • If the discoloration is the result of an underlying condition such as diabetes, it may be necessary to gain more control over your health to see any improvement.
