What condition results from a deficiency of calcium?

The condition that results from a deficiency of calcium is Rickets, not Osteoporosis. Rickets specifically occurs in children due to insufficient vitamin D, calcium, or phosphate, leading to various skeletal deformities such as soft and weak bones. In contrast, Osteoporosis is a condition that typically arises later in life, characterized by the loss of bone density and strength, often associated with aging or hormonal changes rather than a direct calcium deficiency during developmental years.

Calcium is crucial for maintaining bone health, so while both Rickets and Osteoporosis are related to calcium, they manifest under different circumstances and age groups. Osteoporosis involves a gradual loss of bone density and is more about the weakening of bones due to age and other factors, rather than a direct deficiency during growth. By understanding the specific role of calcium in bone health, one can clearly see how Rickets directly results from a lack of calcium in the growing skeletons of children.
