骨質疏鬆會否影響跌倒？

會容易跌倒, 因為骨骼是好像一條鎖鏈, 互扣住.
骨質疏鬆是骨骼互扣不緊而引致, 所以會容易跌倒.

yes, they are inter-related.

however, you can do sometimg to prevent this happen, like do more exercise or take drugs.

my family doctor in Tai Wai (Dr. Ho) is quite good on this and he can tell you what happen (because my friendi have seen him 1 months ago for the same problem),
he gave my friend drugs to prevent 骨質疏鬆 (only one tablet per week)
he is very nice and may be you can see him if he can help you.
His clinic Tel no 2634 5530

Hope he can help you.
