Rickets is a condition that affects the development of bones in children. It affects the skeleton causing the bones to become weak and soft. Weak and soft bones lead to skeleton deformities and poor growth. Rickets is caused by a severe and prolonged deficiency of vitamin D.
Rickets is a problem in growing children in which the newly formed bone matrix does not mineralise properly. It indicates a deficiency of the bone constituents such as calcium, phosphate etc. Some children with hypocalcaemia (a condition characterized by calcium deficiency) are found to have rickets, but not all children with rickets will be hypocalcaemic.
