What condition is characterized by porous, brittle bones?

Osteoporosis is characterized by porous, brittle bones due to a decrease in bone density and mass, which increases the risk of fractures. This condition often occurs as a result of aging, hormonal changes (especially a decrease in estrogen in postmenopausal women), and a lack of calcium and vitamin D in the diet. As bones become less dense, they lose their structural integrity, making them more susceptible to breaks from falls or even minor injuries.

In contrast, rickets is a condition primarily affecting children, resulting from a deficiency of vitamin D, calcium, or phosphate, which leads to softened bones. Scurvy, on the other hand, stems from a deficiency of vitamin C and affects collagen synthesis, leading to symptoms related to the skin and connective tissues rather than bone density. Hypertension refers to high blood pressure and does not relate to bone health. Understanding osteoporosis is crucial for recognizing the importance of bone health and the preventive measures that can be taken, such as maintaining a balanced diet and engaging in weight-bearing exercises.
