Menopause is one big cause of osteoporosis and/or osteopenia. Once diagnosed, it is important to make sure you get enough calcium daily as well as incorporate weight bearing exercises to help improve osteoporosis.
A test that is better than dexascans is the REMS. Comparing dexascans requires doing the test on the same maching - Why? because these machines are manufatured by different companies.
My doctor recommended the REMS - a new test out there so you may need to hunt one down in your area or somewhere near you. What I loved about the REMS is that it also gives your fracture risk. And again, I was told that adding calcium rich foods into my daily diet and weight bearing exercises are critical to increasing bone density. I purchased a weight bearing vest I wear when I walk. I also purchased ankle weights that I use when I walk. Both can be purchased on Amazon.
