What is a common reason for osteoporosis?

The development of osteoporosis is frequently linked to hormonal changes, particularly the decline in levels of estrogen in women during menopause and testosterone in men as they age. Estrogen plays a crucial role in maintaining bone density, and its reduction leads to an imbalance in bone remodeling, where bone resorption outpaces bone formation. This increases the risk of fractures and decreases overall bone strength, making the identification of decreased levels of these hormones as a common reason for osteoporosis well-founded.

In contrast, increased physical activity is generally beneficial for bone health, as it helps build and maintain bone density. Excessive calcium intake does not typically contribute to osteoporosis; rather, adequate calcium is essential for bone strength. High levels of vitamin D support calcium absorption, which is necessary for bone health but does not lead to osteoporosis.
