1. The most important change in this vitamin deficiency is an increased loss of calcium and phosphate in the stools. This leads to a fall in their blood level and hence not available for bone formation. Due to this reason, the children suffer from rickets and adults from osteomalacia.
2. Rickets occur in children between 6 and 18 months of life during the period of skeletal growth. The bones become soft and easily bent. Under the constant pull of the muscles, the joints lose their shape and are not able to function, as they should.
3. The disease is characterized by growth failure, bone deformity, muscular hypotonia, tetany and convulsions due to hypo calcemia.
4. In young infants there may be a marked softening of the bones of the skull. The head may be flattened on one side. Premature infants are more prone to have rickets.
5. The danger is great to darker skinned children who live in cooler climates. Breast fed babies are more likely to develop rickets if the mother is not on a well balanced diet.
