Why do you get white spots on your fingernails?

Have you ever had one of those white spots on your fingernail and wondered what it was?

Well wonder no more! The majority of white spots on fingernails are caused by a previous injury to the nail bed. They can be loosely compared to bruises on the skin.

Similar to bruising, white spots on fingernails do not show up immediately. It may take several days or weeks before you notice the spots. Because they are generally the result of a minor injury, by the time you notice the spot you are likely to have forgotten all about banging your fingernail a few weeks earlier.

The medical term for white discoloration appearing on nails is Leukonychia. And it is certainly one of the better nail conditions to have, some are far, far worse.

While these white spots may be the result of a zinc deficiency, if it is, it’s likely that other signs of zinc deficiency, such as hair loss or a slow immune system, would be present as well.

    Haha wow, this is such a random topic, but I completely was curious about it xD. I hate those white spots (I think they look more like dashes). I kind of figured that it was something to do with like banging the nail but since it doesn’t show up for a while, like you said..I completely forgot about lol.

    You have a great site. Thanks for your contributions. I have had personal experience with white spots on my fingernails that was clearly the result of a zinc deficiency. I have also noted this in patients of mine. And you are right, if a lack of adequate amounts of zinc is the culprit, looking deep enough will reveal other signs and/or symptoms of zinc deficiency.
