As a child, who has not been told? Those spots of the nails come out for lack of calcium. Even that sprouted for every sin or lie of the child. Let’s see, why do white spots appear on nails?
The fingernails grow faster than those on the feet, approximately 2 to 4 millimeters each month. This is maintained throughout life in the absence of diseases.
Hence it has been heard that nails continue to grow after death. Well, this is false, what happens is that visually it seems because the flesh of the body shrinks and causes it to stand out more.
The true mystery is the white spots, of which much has been written, and which in medical terms is called leuconiquia punctata, and its appearance is due to the disposition of keratin as a result of tiny ruptures that occur at the base of the nails, favoring the formation of small air pockets.
Keratin is a fibrous and insoluble protein. It is the main constituent of hair and nails.
Therefore, they appear when blows are suffered in the fingertips without noticing it. As the nail grows, they will move towards the end until they disappear.
In this way, one can “partially” believe that when there is a deficit feeding, spots may appear, but not because of the feeding itself, but because the nails are weaker and more susceptible to shocks.
Leuconiquia has different types and can appear as a result of various diseases such as kidney disorders.
