During adolescence, there are marked changes in the metabolism of calcium and phosphorus and a dramatic increase in the rate of bone mineralization under the influence of the sex hormones, growth hormone, and insulin-like growth factor-1. More than 50% of adult bone mass is accumulated during puberty; failure to achieve maximum bone mineralization at this time may lead to osteopenia and its complications in later adulthood. This article discusses the causes, evaluation, and management of adolescents with hypocalcemia, hypercalcemia, and disorders of bone mineralization.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
