Seniors who have developed a 'hump' in their upper back have had several compression fractures of vertebrae due to osteoporosis.
Looking at prevention, small changes can make a huge difference. Not all supplements are equal. A quality mixed calcium supplement is essential. Changes to physical activity are also important. Ask your doctor what you can do to avoid this issue.
