What is a common risk factor for fractures in postmenopausal women?

Hormonal changes are a significant risk factor for fractures in postmenopausal women, primarily due to the decrease in estrogen levels following menopause. Estrogen plays a crucial role in maintaining bone density by inhibiting bone resorption. When estrogen levels drop, the balance between bone resorption and formation is disrupted, leading to increased bone loss and a higher risk of osteoporosis and fractures.

Understanding the impact of hormonal changes highlights the importance of monitoring bone health in postmenopausal women. Strategies to mitigate the risk often include lifestyle modifications and medical interventions that focus on hormone replacement therapy or other treatments to maintain bone density.

Increased calcium intake and low vitamin D levels, while important for overall bone health, are more related to dietary factors rather than the direct hormonal changes that occur during menopause. High physical activity generally contributes positively to bone health; however, excessive physical exertion without proper precautions can also lead to injury, including fractures.
