What is a primary cause of osteoporosis?

Osteoporosis is a condition characterized by weakened bones and an increased risk of fractures, primarily due to a decrease in bone density and strength. One of the primary causes of osteoporosis is decreased calcium absorption. Calcium is a vital mineral necessary for maintaining bone health, as it is a key component of bone tissue. When the body has insufficient calcium due to decreased absorption from the diet or other factors, it can lead to a reduction in bone density over time, increasing the likelihood of developing osteoporosis.

When calcium levels in the body fall, the parathyroid hormone is released, which stimulates the release of calcium from bones to maintain normal blood calcium levels. This process can lead to a further reduction in bone density if calcium absorption does not improve. Consequently, identifying and addressing decreased calcium absorption is crucial for preventing and managing osteoporosis.

In contrast, an increase in bone density would actually be protective against osteoporosis, while regular weight-bearing exercise is beneficial for bone health, as it helps maintain and build bone density. Overconsumption of dairy is generally not linked to osteoporosis; in fact, dairy products are often promoted for their calcium content, which supports bone health when consumed appropriately.
