Osteoporosis makes the bones of the elderly fragile and more prone to fractures. Common fracture sites include the hip, spine, and wrist. This can not only cause pain but also limit their mobility, making simple daily activities such as walking, bending, or even lifting objects difficult. Severe fractures might require surgery and long-term rehabilitation, and can even lead to prolonged bed rest, increasing the risk of other health issues like pneumonia or blood clots.
