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.
A lack of vitamin D â known as vitamin D deficiency â can cause bones to become soft and weak, which can lead to bone deformities. In children, for example, a lack of vitamin D can lead to rickets. In adults, it can lead to osteomalacia, which causes bone pain and tenderness.
