Osteopenia and osteoporosis are conditions that cause bones to become weak and brittle. They are most common in older adults, but they can also occur in younger people. There is no cure for osteopenia or osteoporosis, but there are treatments that can help slow bone loss and reduce the risk of fractures. If you are concerned that you may have osteopenia or osteoporosis, it is important to talk to your doctor. They can do a test to measure your bone density and recommend treatment options.
