Tetany: A disease condition due to low levels of calcium (hypocalcemia) in the body that causes cramps and spasms in the hands, feet, and larynx (voice box).

Osteomalacia/Rickets: A disease caused by softening and weakening bones in children due to inadequate vitamin D. Hypoparathyroidism: It is a disease characterized by low parathyroid hormone levels. This can cause low calcium levels and trigger tetany (muscle cramps, spasms or tremors).
