First, you need to be congratulated! Strength training, jogging, eating well have made an enormous difference in reducing your risk for fractures due to osteoporosis. It is not uncommon for one part of your skeleton to react differently than another part. The fact that your hipbone density has increased so dramatically is wonderful. Your spine has stayed about the same-within the normal variation of the machine. I would talk with an exercise trainer at your health and fitness center to make sure that you are getting enough "core" exercises for your back. He or she may have you do some abdominal curls, upper back, and back extension exercises. These core exercises may help to improve your spine bone density. I would also make sure that you are getting at least 500 mg a day of calcium citrate (such as Citracal brand) and 400 to 600 IU of vitamin D. The calcium, vitamin D and the exercise will all work together to reduce your risk of fractures. Finally, if necessary, I would talk with your doctor about medications. Depending upon how low your bone density is, medications can make a big difference. Keep up the good work!
