At the 21st century, and is still alive version of that white spots on the nails - this is a good news or good fortune. More versions exist, they are due to mechanical damage to the nail or a lack of vitamins. Which of these versions is plausible? Now face it.
These white pieces on the nail plate has its own name - Leukonychia. Is it a disease? No, but a very good indicator of some disturbances in the body, which are discussed below.
As formed Leukonychia
To begin, how generally formed nail. Under the rear roller nail matrix is we - the same conveyor living cells that then arises nail. These cells - onihoblasty. The matrix onihoblasta parent cell divided-divided, and the new cells are identical over the parent. fission process continues throughout our lives.
Onihoblasty accumulate in layers, they become crowded and begin to push the previously formed rows forward, toward the tip of the nail plate. At the base of the nail, each of us sees the white crescent - a zone lunula. We can say that it is a kind of lunula transitional stage of living cells in the "dead". From the moment of his birth onihoblasty begin to synthesize keratin. Going into the dead state of the cells - is keratinization, ie cells are completely filled with keratin. That's all. So we formed the nail plate, made of keratin (or rather - beta-keratin).
During the "immobilization" onihoblastov might go something like this. Namely, this body-established operation, air may get, will fail in the keratin on the nail and we will see those white spots that call Leukonychia.
Reasons Leukonychia
Let us examine what prevented onihoblastam is filled with keratin. The reasons fall into two categories: external and internal (those that depend on our body).
Let's start with the easiest - to external causes. White spots on the nails may occur due to mechanical trauma to the nail (for example, stronger than a thin hit on the nail or gel extensions did wrong master), And could be formed due to the abrupt climate change. It is possible that Leukonychia could be formed due to chemical damage to the nail.
If the human nail plate is not faced with the above factors, but there are white spots, it's cheerless news. Because the remaining causes of their formation are internal. And the presence of white spots on nails or slips in this case indicate its owner that it is time to pay a visit to the doctor.
internal causes Leukonychia:
1) zinc deficiency in an organism (it happens quite often in pregnant women);
2) too rigid diet (that, in fact, harmful, limit yourself to food, you should not, and effective weight loss that does not help, it is proved by all literate biohakerami);
3) severe stress;
4) gastrointestinal disease, disorder of the digestive system and the general metabolism;
5) psoriasis;
6) diabetes;
7) heart failure;
8) the presence of the fungus on the nails;
9) kidney or liver disease;
10) prolonged use of medications (especially drugs of sulfonamides);
11) vitamin deficiency;
12) heavy metal poisoning.
That's it. The lack of vitamins - that's just a drop in the sea of all the causes of Leukonychia. But more often, for example, white paired bands, which are located on the nail plate from side to side indicate that the body is not very much like the current diet.
Spot Leukonychia mainly occurs due to mechanical damage of the nail. A large white spot on the nail plate, usually occurs due to extreme stress.
Total Leukonychia (when the nail plate is almost completely white) Or produced because of fungus or a signal of serious damage to any of the internal organs.
As you can see, the list of internal reasons are not very bright, so to see white spots / stripes the nails, it's for good luck - some black humor that fans of mysticism and superstition is not exactly understand.
