Many people at some point in life have white spots on their fingernails. One
of the most common causes for these little white spots is a condition called
leukonychia. Although the name sounds pretty serious, the condition typically
16 . And while many people think the white spots are caused by a calcium or
zinc deficiency, that’s generally not the case. In reality, these spots most
often develop 17 mild to moderate trauma to your nail. If you can’t think of
anything that would have injured your nail, consider the fact that nails grow
very slowly, so the injury 18 weeks before the spots ever appeared. The spots
could also be a sign of a mild infection or allergy, or a side effect of
certain medications. 19 the source of the injury, these spots typically do
not require any treatment and should go away as your nail grows out. And they
should not return unless you suffer another injury to a nail. However, this
generally 20 when only a single or a few nails are affected. If all of your
nails are showing white spots, the leukonychia could be related to another
more serious condition such as anemia, cardiac disease, diabetes, or kidney
disease.
