Why do children have white spots on their nails?

White spots on children's nails are actually a reflection of the child's physical health. If there are white spots on children's nails, it may be a sign of zinc deficiency. Therefore, parents should pay attention to observe whether their children have these abnormal phenomena in life. Only when we know more about these common sense, can we discover in time whether their bodies are affected by this problem.

Obvious signs of zinc deficiency. Make up for it quickly, look at my repost below, it would be uncomfortable to be involved in any of them, right? ! ! ! !

1. Anorexia is one of the early symptoms of zinc deficiency in children. It is caused by reduced taste sensitivity. Zinc in the human body mainly affects taste and appetite through a zinc-containing salivary enzyme medium. It is known that taste is a nutritional factor for oral mucosal epithelial cells. After zinc deficiency, the oral mucosal epithelium proliferates and keratinizes incompletely, the half-life is shortened, and it is easy to fall off, blocking the taste bud holes in the papilla, making it difficult for food to contact the taste buds, not stimulating the taste, affecting appetite, and causing anorexia in children.

2. Pica. Pica is also a common symptom of zinc deficiency in children. Due to zinc deficiency, the regeneration of taste bud cells on the tongue is impaired, the taste buds are reduced, and the sense of taste is weakened. The sensitivity to the four tastes of sour, sweet, bitter and salty is significantly reduced, and the taste cannot be distinguished. Chewing as a foreign body is a hobby, which is the main reason. According to reports, the onset age of children ranges from 1 to 10 years old, with the majority being 1 to 5 years old. There are slightly more boys than girls. The course of the disease varies in length and the types of food included are many. They may eat soil, coal slag, paper, wall lime, eggshells, cigarette butts, fingernails, hair, sand, soy sauce, salt, etc., or several.

3. Digestive dysfunction Reduced digestive function is another result of zinc deficiency. Zinc deficiency impairs protein synthesis and reduces stability, causing lysozyme in pancreatic cells and cell autolysis. Zinc deficiency can reduce the formation of carboxyl complexes. When zinc is deficient, the synthesis of the outer membrane is impaired, causing erosion and fusion into large fat droplets, which are not easy to pass through the intestinal epithelium. Therefore, the patient's fat absorption disorder is prominent. The clinical manifestation is chronic diarrhea, which leads to digestive dysfunction.

Because in many cases, a child's physical health condition will be reflected in some of her physical characteristics, so the key lies in the parents. When taking care of children when they are young, they should pay attention to observe whether their children have some abnormal symptoms in their bodies. This way they can remind and help them prevent and avoid these problems in a targeted manner.
