Complications Because<unk>  is caused by the loss of bone mass due to aging, the bones are more fragile and thus more prone to fractures and fracture-related complications. These complications can include a more than doubled risk increase for future fractures and a lower quality of life resulting from chronic pain or disability, sometimes needing long-term nursing care. Depending on the site, pathologic fractures can also increase relative mortality risk. Hip fractures alone are particularly debilitating and have a nearly 20% higher mortality rate within one year of the fracture. Other fractures are more subtle and can go undetected for some time. For example, vertebral compression fractures in the spine, often noticeable by a loss of vertical height, can occur even during routine motions like twisting, coughing, and reaching. In addition to decreased bone mineral density, there are other factors that contribute to fracture risk such as advanced age, lower body mass index, fracture history, smoking, steroid use, high alcohol intake, and fall history. Studies linking alcohol and fracture risk define high intake as three or more drinks per day. High caffeine intake may also play a role in fracture risk. Many healthcare organizations also utilize a Fracture Risk Assessment Tool (FRAX) that can estimate a 10-year probability of having an osteoporotic fracture based on an individual's health information and the criteria listed above.
