Is the child suffering from pillow baldness and costal valgus a sign of calcium deficiency
This is a question that parents often ask. Some newborns can have alopecia several weeks after birth, which is called physiological alopecia. The newborn's hair is fine and light. The growth period of lanugo is relatively short, and the child lies rubbing and sweating more, so there is pillow baldness. It can be sudden or insidious alopecia. Hair follicles start to become active after the age of one year, and can generally recover. Few can be prolonged for several years, and can eventually recover. This is a special manifestation of normal newborns. Similarly, the costal edge valgus mainly refers to the valgus of the ribs of thoracic 12, which is due to the change of gravity during the development of the ribs from the lying position to the sitting position and standing position, and at the same time, the diaphragm pulls the ribs of thoracic 11. This is a normal condition during the development of young infants, which is not a sign of vitamin D deficiency rickets. It is not a sign of calcium deficiency. As the child gradually develops, the thorax will return to normal. This is not a sign of rickets or hypocalcemia. It is wrong to take calcium supplements.
