What is the primary cause of Rickets in children?

Rickets is primarily caused by a deficiency of vitamin D, which is essential for the absorption of calcium and phosphate in the body. This deficiency leads to inadequate mineralization of the bones, resulting in soft and weak bones that can deform. In growing children, this can manifest as bowed legs, thickened wrists and ankles, and other skeletal abnormalities.

Vitamin D can be obtained from sunlight exposure, certain foods, and supplements. When children do not receive enough vitamin D, either from their diet or sunlight, their bodies struggle to maintain adequate calcium and phosphate levels, directly affecting bone health and leading to rickets.
