Nail leukoplakia may be a disease of the nail itself, such as the problem of congenital nail metabolism; it may also be intestinal ascariasis, which is often referred to as “plaque”, and some people think that it is related to calcium deficiency and zinc deficiency, but there is no exact evidence. If the white spots disappear with the growth of the nails, you don't have to worry. If you don't retreat for a long time, you should see a dermatologist.
