This leads to secondary hyperparathyroidism (overactive parathyroid glands attempting to keep blood calcium levels normal). To try to balance calcium levels in your blood (via secondary hyperparathyroidism), your body takes calcium from your bones, which leads to accelerated bone demineralization (when a bone breaks down faster than it can reform). This can further result in osteomalacia (soft bones) in adults and rickets in children. Osteomalacia and osteoporosis put you at an increased risk for bone fractures. Rickets is the same as osteomalacia, but it only affects children. Since a child’s bones are still growing, demineralization causes bowed or bent bones. Who does vitamin D deficiency affect? Anyone can have vitamin D deficiency, including infants, children and adults.
