Why enrich the calcium and return the calcium deficiency all the time
Q: It is 65 year old this year such as I, be begun from 50 year old to enrich the calcium, taken by a lot of kinds of calcium tablets,but before speak some celestial body by I calcium deficiency also when not examining. Someone says the method that I enrich the calcium is wrong, someone says I have not selected calcium tablet correctly. I'd like to ask you, how should the elderly enrich the calcium? Qin Ying in Beijing answers: The normal absorption rates to various calcium pharmaceutical of people are generally about 30%, have no difference domestically and import oral calcium pharmaceutical, but select arbitrarily for use. But if the human body lacks the gastric acid, the absorption of various calcium preparation is obviously different. Because all internal organs function of the elderly's organism fails gradually, especially decline of the digestive system, 20%~60% of the old persons will present achlorhydria, is shown as nutrition absorbs slowing down, digestive juice to secrete and reduce. It is an important factor influencing the gastric acid to secrete that the mucous membrane of stomach withers, it is between twenty and fifty and achlorhydria can cause dissociation and uptake of calcium to be obviously lower than. So the elderly take the correct method of enriching the calcium, choose appropriate calcium preparation it is particularly important. Medicines can roughly be divided into two kinds inorganic calcium preparation and organic calcium preparations enriching the calcium on the market at present. Old patient should one-sided to choose the intersection of calcium and the intersection of element and the intersection of content and high inorganic calcium. If the element content of calcium of calcium carbonic acid is up to 40%, but its water-solubility is low, under the environment of achlorhydria, it is slow to disintegrate, dissociation is incomplete, extremely apt to cause the gastrointestinal tract to stimulate symptom, extremely unfavorable to the old patient. The elderly should choose the intersection of water-solubility and fine organic the intersection of calcium and preparation first, such as amino acid chela shut calcium, the intersection of citron and the intersection of acid and calcium, the intersection of glucose and the intersection of acid and calcium, the intersection of acetic acid and calcium, the intersection of lactic acid and calcium,etc., because they are slilghtly influenced by gastric acid. In addition, factors such as structure and preparation craft of calcium preparation,etc. have influence greatly on the absorption of calcium pharmaceutical. Such as ultra little powder calcium preparation and amino acid calcium preparation carbonic acid, it is the living beings that utilize degree higher calcium pharmaceutical. The chela utilizes the chela to shut technology and hold single calcium in place with a net and mix together with, release calcium ion slowly to shuts calcium, increase the absorption rate of calcium. By contrast, the absorption summit of single calcium causes the blood the density of calcium ion rises rapidly, discharge by the renal supersession, will bring certain presure to kidney. Need to pay attention to, because of old patient's achlorhydria, oral calcium preparation should generally or take in two meal after a meal, uncomfortable by reducing the stomach. In addition, the stimulus of the food will make the gastric acid secrete and increase, promote the dissociation of calcium preparation. If necessary, can also give the clothes with acid fruit juice such as acid, malic acid of the citron, in order to improve the acidity of the gastric acid. Moreover, vitamin D can promote the gastrointestinal tract uptake, bone ore, bone of calcium to take shape, the reabsorption to calcium of strengthening the kidney, preventing the occurrence of kidney stone and mediation blood calcium level,etc.. So, when the elderly enrich the calcium, should supplement sufficient vitamin D, in order to enable calcium to be utilized by the organism to the maximum extent.
