Osteoporosis remains a vastly underdiagnosed and undertreated disease, despite the enormous toll it takes on the world’s older populations and healthcare systems worldwide. Even after patients suffer a broken bone due to osteoporosis, it is estimated that around 80% are not diagnosed and treated to prevent recurring fractures. This is why World Osteoporosis Day, marked every year on October 20th, is a vitally important occasion to drive much-needed awareness for bone health and the prevention, diagnosis, and treatment of osteoporosis and fragility fractures.
