Why talk about this topic?
Because many people go to the hospital to draw blood and find out, heh! My blood calcium is normal, so I think there is no calcium deficiency. Of course, bones are certainly fine, but this idea is very, very wrong.
Why do you say that? Because the calcium in our body is mainly divided into two parts:
The first part, in our blood, is only 1 percent.
The second part, inside the bones and teeth, is 99 percent.
Although there is only 1% calcium in the blood, this 1% is particularly important. Because it maintains your basic life activities, such as this 1% of your heart can beat normally, and this 1% of you can only hold things or walk to have strength. If this calcium is particularly low, let alone take something, you can't even lift a hand.
Therefore, our body itself is a very intelligent machine, when this blood calcium is low, we must ensure my most basic life activities, that is, we must ensure that I am alive. So, just a little bit lower, it will take calcium from the bones. to supplement this 1%. Therefore, our blood calcium is generally not low; But little by little, the process of taking calcium from the bones is not perceived by the body.
This is actually a bit like cash and bank cards, calcium in the blood is equivalent to cash, and calcium in the bones is equivalent to bank cards. When you don't have enough cash to spend and can't support your daily life, you must go to the bank card to withdraw it. This happens unconsciously, and you don't realize it, until one day you find out, hey, there's not much money in the card; The calcium in the bones is also lost little by little, unknowingly.
Therefore, whether your blood calcium is normal or abnormal, and whether you have leg cramps, palpitations, palpitations, etc., you must check bone density. Only by checking bone density can you know whether your bone density is normal and whether it is really calcium deficiency?
