Osteoporosis is a medical condition characterized by a significant decrease in bone mineral density, which results in bones becoming fragile and more susceptible to fractures. This condition often develops silently over many years and can lead to serious complications, such as fractures from minor falls or injuries. The decrease in bone density occurs when the creation of new bone doesn't keep up with the removal of old bone. Risk factors for osteoporosis include aging, hormonal changes, nutritional deficiencies (especially calcium and vitamin D), and a sedentary lifestyle. Understanding osteoporosis is crucial for prevention and management, as it can significantly impact quality of life.
