Are Your Bones Healthy?
There are however quick at home tests for you. If your spine is healthy then your arm span should equal your height, but your arm span measurement greater than your height? Yes, Michael Phelps was born this way with those butterfly swimming long arms, but for many of us we were born with the arms span equal to our height. If you now have that ratio changed. it means there maybe osteoporotic fractures of the spine causing wedging that leads to the curved and crumpled back posture. Try sitting on the floor and then stand, without using arms, and then balance separately on each foot. Bad balance may be a sign of bone issues as well
The most accurate test is bone densitometry testing. DXA tests give you a T-score measurement of bone strength. There is actually no specific number on your bone test that is completely “safe” from fracture, but the denser your bones on this test the less likely it is that you will fracture. Also look at the numbers that give a percentage of change over a 2-5 year period of time. the weakest bones are associated with measurements that show bone lost is proceeding rapidly, even if the scores are still in the healthy range. Women in pregnancy can lose 3-5% of their bone, if you breast feed you can lose 10% of your bone (but delivery and stopping breastfeeding triggers rapid re-growth), in menopause women will lose 2-4% of their bone per year, and as women get older they will lose about 1-2% of bone per year. Treatments can halt or dramatically slow these numbers.
