| BMD decrease from L1 to L4.
Hi, friends, I am new here and this is my first post. And I'm not a native English speaker, so if my wording confused you, please let me know.
I'm 26 years old, male, Chinese race. Weighting 70 Kg (154 Lbs), Height 180 cm (5.9 feet).
I did a DEXA scan on Feb 28th 2017, machine type: Lunar iDXA ME+200494. The BMD in hip is fine, with a T-score of 0.2, but BMD in spine confused me:
Region BMD(g/cm2) T-score Z-score
L1 0.946 -0.6 -0.7
L2 1.014 -0.6 -0.8
L3 1.014 -0.8 -0.9
L4 0.856 -2.0 -2.1
L1~L4 0.949 -1.1 -1.3
All my research tell me the BMD will increase downward(from L1 to L4), but mine obviously do the opposite: L4 is the weakest. This frighten me, does this suggest I might have some condition that I don't know? BMD scan have no data on L5, will it even weaker than L4? Why my L4 so special?
The doctor tell me no worry, he only care about the overall density. But I'm afraid, since this is quite abnormal. Please tell me what can you read from the result, or do I need some other test. Any reply is appreciated.
