Bone health is important for our bodies. Osteoporosis and osteomalacia are two diseases that affect the bones. While both weaken the bones, they act differently. Understanding the difference can help you discuss symptoms with a doctor and get the right diagnosis and treatment. Osteomalacia is a condition that softens bones, often due to a vitamin D deficiency which helps in calcium absorption. In children, it's called rickets. On the other hand, osteoporosis decreases bone mineral density and changes bone structure over time, weakening the bones and increasing fracture risk. The biggest risk factor for osteoporosis is age, as the body breaks down bone faster than it rebuilds it. Osteomalacia treatment usually involves vitamin D, calcium, or phosphate supplements, while osteoporosis treatment focuses on slowing or stopping bone loss and preventing fractures.
