Vitamin D deficiency: When a person cannot get enough Vitamin D through food and exposure to sunlight, it leads to vitamin D deficiency. It often leads to thin, brittle, or misshapen bones.

Osteoporosis: Osteoporosis is a bone disease that weakens and brittle bones by decreasing bone density. 

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: Osteomalacia/Rickets disease is 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).
