Osteoporosis is characterized by a decrease in bone density, leading to weakened bones that are more prone to fracture. Some of the common signs and symptoms of osteoporosis include a gradual loss of height, a stooped posture, back pain as a result of fractured vertebrae, and an increased risk of fractures following minor falls or even sudden movements. These fractures often involve the hip, wrist or spine and can have serious consequences if left untreated. Additionally, some people with osteoporosis experience no symptoms at all until there is an acute fracture with associated pain.
