There are various reasons toenails can become yellow, but the most likely explanation is a case of toenail fungus. Fungal infections in the toenails are rather common. The responsible fungi are microscopic—so you will not see them and know to avoid the tiny spores—and often reside in areas where people walk barefoot (gym locker room floors, communal showering areas, indoor pool decks).

Beyond fungal toenails, other causes of yellow toenails include diabetes, tuberculosis, bronchiectasis, jaundice, psoriasis, and thyroid problems. In some cases, nails become yellowed simply due to natural aging processes. There is also an extremely rare genetic disorder known as “yellow nail syndrome,” which can be seen in conjunction with lymphedema.

If your toenails are yellow due to a fungal infection or diabetes, be sure to come in and see us here at Southern Oregon Foot & Ankle.  Keep in mind the fact that toenail fungus usually does not not go away on its own. There are also special measures you need to take with regards to diabetic foot care and potential infections.

Of course, you should request an appointment with our Medford office if you are suffering from any other foot or ankle condition as well. For more information about either foot care or our practice, or to schedule your visit, simply give us a toll-free call at (541) 776-3338 and our staff will be glad to help.
