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.
Low vitamin D can result in elevation of the PTH (parathyroid hormone). When the vitamin D is low, it can result in inadequate absorption of calcium and when that occurs, the parathyroid takes action to make sure there is adequate calcium in your blood. So, it is important to have adequate vitamin D, as well as adequate calcium, daily.
