Kids and Vitamin D Deficiency. ââââââRosemont, IL, October 17, 2012 â A startling increase in the frequency of severe vitamin D deficiency is being reported in the U.S. and other countries. This severe deficiency can have a devastating impact on a childâs bone strength, the United States Bone and Joint Initiative (USBJI) says.
Symptoms of Vitamin D Deficiency. Severe Vitamin D deficiency in children causes them to get the bowed legs, and sometimes arms, that are characteristic of the soft bone disease of rickets. In adults, this severe form of low Vitamin D causes a disease called osteomalacia, and can be a precursor to osteoporosis. Osteomalacia is similar to rickets, as it is a softening of the bones, but it doesnât lead to bowed legs as it does in children.
