一些中老年人在体检时,发现自己的血钙水平明显增高,便认为自己体内不缺钙而无需补钙了。其实,这是一种误解。在正常情况下,体内的钙大部分以磷酸钙和碳酸钙的形式储存于骨骼中,血液中的钙还不到全身总量的1%。一旦血钙低于生理水平,神经肌肉兴奋性会立即升高,引起肌肉自发性收缩,医学上称之为抽搦(俗称抽搐),还会引起低血钙、高血磷现象,导
Some middle-aged and elderly people found that their blood calcium levels were significantly higher when they were on physical examination, and they thought they did not have calcium deficiency without calcium supplement. actually it is a kind of misunderstand. Under normal circumstances, most of the body’s calcium is stored in the form of calcium phosphate and calcium carbonate in the blood, the calcium in the blood is less than 1% of the total body. Once the serum calcium below the physiological level, neuromuscular excitability will immediately rise, causing spontaneous muscle contraction, medically known as pumping 搦 (commonly known as convulsions), can also cause hypocalcemia, hyperphosphatemia phenomenon, guide
