What can cause your finger nails to turn a shade of yellow?

…other than that :P

Nail polish that is dark like red, black, purple, blue, can stain the top layer of your nail. Fungas can turn your nails yellow too. If it’s stained, you can just file off the top layer, if it’s infected you need to see a doctor.

. The are a lot of possible causes, and I quote the following: … Yellow fingernails may act as a warning sign for diabetes, kidney, liver or lung disease and iron or zinc deficiencies. Although such internal disorders typically are not the cause of yellow fingernails, seeing a health-care professional is highly recommended if your nails change color suddenly. . Fungal infections are the culprit in about half of the cases involving discolored fingernails. After an initial yellowing of the fingernails more symptoms will appear, including a flaking of the nail and an unpleasant odor. Individuals with a fungal infection should see a physician to obtain prescription medications. . Simple blood tests can generally rule out most causes of yellow fingernails. However, a more detailed diagnostic workup may be required to identify what is known as yellow nail syndrome. In addition to yellowing of the fingernails, symptoms include respiratory tract abnormalities and/or localized fluid retention. …” From the website at: http://funadvice.com/r/15il2hvogli .
