Paget's Disease is a chronic bone disorder that disrupts the normal cycle of bone renewal. In this condition, the bones become enlarged and weakened, leading to pain, deformities, and an increased risk of fractures. It most commonly affects the pelvis, skull, spine, and legs, and while the exact cause is unknown, genetic factors and viral infections may play a role. Symptoms can vary widely; some people may not experience any symptoms at all. When symptoms do occur, they can include bone pain, joint pain, and noticeable changes in bone shape. Treatment often involves medications like bisphosphonates to help manage symptoms and slow down the disease's progression.
