Final answer:
A decline in bone mineral density due to osteoporosis is a key reason older adults suffer bone fractures. The condition leads to brittle bones that are prone to fracturing from mild trauma or even everyday activities. Maintaining bone health is crucial to prevent osteoporotic fractures.
Step-by-step explanation:
A key reason older adults suffer bone fractures is because of a decline in bone mineral density, which is part of a condition known as osteoporosis. This disorder generally occurs in older adults in which bones lose minerals, such as calcium and phosphate, making them brittle and more prone to breaking easily upon mild trauma. The reduced bone density means that the osseous tissue may not provide adequate support during everyday activities, making even a sneeze potentially capable of causing a vertebral fracture.
Furthermore, the risk of osteoporotic fractures is highly concerning as they can lead to debilitating pain, further disability, and even early mortality due to complications such as deep vein thrombosis, pulmonary embolism, and pneumonia. Risk factors for osteoporosis include older age, genetics, hormonal changes, and lifestyle factors like smoking, inadequate exercise, and poor nutrition. It is essential to maintain healthy bones through a balanced diet rich in calcium and vitamin D, regular exercise, and avoiding smoking and excessive alcohol consumption, to reduce the risk of osteoporosis and subsequent fractures.
