Question

If a child frequently bites their fingernails until the red flesh is exposed, and they sweat excessively during naps and easily wake up, could these be signs of calcium deficiency? What are the typical manifestations of calcium deficiency?

Answer

When children exhibit symptoms such as excessive sweating, difficulty falling asleep, easy waking, loss of appetite, late teething, and delayed growth, it may be necessary to consider the possibility of calcium deficiency. These symptoms are often related to the growth of the child’s bones and the development of their nervous system.
