Osteoporosis and osteomalacia are both conditions that affect the bones, but they have different causes and treatments. Osteomalacia means the bones become soft, mainly due to a deficiency in vitamin D, which leads to poor calcium absorption. In children, osteomalacia is known as rickets. Osteoporosis means the bones lose density and quality, making them weak and more prone to fractures. The main risk factors for osteoporosis are aging and menopause. Prevention and treatment of osteomalacia typically involve supplementing vitamin D and calcium, while treatment for osteoporosis focuses on preventing bone loss and fractures. Regular check-ups and early diagnosis are crucial for effectively managing both conditions.
