Which factor contributes to osteomalacia?

Osteomalacia is a condition characterized by the softening of the bones, primarily due to a deficiency in vitamin D, which is crucial for calcium absorption in the body. A calcium deficiency directly contributes to this condition because, without adequate calcium, bones cannot properly mineralize. This leads to weakened and softened bones, resulting in pain and an increased risk of fractures.

Calcium is essential for maintaining bone density and strength, and its deficiency disrupts the normal bone remodeling process. This connection is why identifying calcium deficiency as a contributing factor to osteomalacia is key in understanding how nutritional deficiencies can impact bone health. In contrast, excessive physical activity may strengthen bones, increased sun exposure usually enhances vitamin D production (which aids in calcium absorption), and excessive protein intake has not been directly linked to osteomalacia.
