First of all, from the origin of the crescent moon, the crescent moon is due to the metabolism of the human body, the rapid growth of nails, and the part of fingers without blood vessels will form a white crescent moon. So children don't have crescent moons, and many old people don't have crescent moons, but that doesn't mean they are unhealthy.
The so-called half moon white, just newborn keratin cells, that is, nails have not hardened and become transparent. The absence of half moon white can directly indicate that nails grow slowly, which may be related to metabolism caused by some physical diseases, or it may be a normal phenomenon, which does not necessarily mean that this person is unhealthy.

Diseases associated with the new moon:
Thyroid dysfunction
If a person's thyroid function deteriorates, his metabolism will be affected, followed by endocrine disorders, and the growth rate of natural nails will slow down, so that the number and area of crescent on his fingers will also change, less and less, and then slowly disappear.
When the thyroid function of human body is in a state of hyperthyroidism, then the thyroid hormone will increase, and the natural crescent will gradually increase after the metabolic rate is accelerated.
malnutrition
If the body lacks nutrition, the speed of metabolism will also slow down, which will also affect the stratum corneum cells, so the crescent moon will gradually become smaller and the disease will tend to disappear.
The crescent moon is milky white. If the color turns red, it may be related to the vascular problems of nail matrix and some diseases, such as venous vasodilation, cardiovascular system, endocrine system, renal system and digestive system diseases.
