The former children never supplemented calcium, and they still grow tall and strong and physically strong. Nowadays, parents start to add calcium before the child is born, but they are often told by doctors: “Children have rickets, and quickly replenish calcium!†Why is the more attention is paid to growth and development? Is it the problem of calcium supplementation or is there any hidden feeling? Ma Yougang, deputy chief physician of Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University explained that rickets in children are not as high as some doctors say. Even if a child has calcium deficiency, it is usually not because of insufficient calcium intake. "More often, we find that vitamin D deficiency leads to the inability of calcium to be absorbed. Therefore, the emphasis should not be on calcium supplementation. Instead, it should be vitamin D supplementation, commonly known as cod liver oil. According to reports, whether the baby eats breast milk or formula milk, Milk is the main food, and eat well, calcium intake is enough before 4 months, do not have to add extra. However, in order to promote the absorption of calcium, vitamin D should be supplemented from the second week after the birth of the child, and the supplemental amount is 400 IU per day. The lack of calcium in children is due to lack of dimensional D What is the real calcium deficiency, many parents actually did not make it clear. Mai Yougang said that infants in the first year need 400-800 mg of calcium per day. If it is three or four months before the baby, drink 120-150 milliliters each time, drink 6-7 times a day to calculate, almost a day to drink about 1,000 ml of milk. Since there is 30-40 milligrams of calcium per 100 milliliters of mother's milk, 300-400 milligrams of calcium in 1,000 milliliters of breastmilk is sufficient to meet the baby's physiological needs. Even if you drink formula milk, the calcium content is similar because it is similar to that of breast milk. Therefore, as long as the child uses milk as the main food and eats well, there will be no problem of insufficient calcium intake. What is the cause of calcium deficiency in the end? He pointed out that in addition to intake, calcium must be absorbed by the body to play a role. However, calcium absorption must rely on the help of vitamin D, which means that as long as vitamin D is insufficient, it will also be calcium deficiency. Therefore, light supplements calcium to children and does not Supplement vitamin D, which is also ineffective. After the baby is born 2-3 weeks should fill D The vitamin D in the baby's body can have three sources: one is the vitamin D reserve from the mother's womb and breast milk, and the second is ultraviolet radiation on the skin, which converts dehydrocholesterol into vitamin D3, which is then metabolized by the kidneys into active vitamin D. Add extra cod liver oil to consume vitamin D. However, vitamin D intake may be affected by various factors in these three links. He added that urban children do less outdoor activities, and air pollution obstructs the sun. Due to insufficient UV radiation, there is insufficient dimension D. Pregnancy, maternal discomfort when supplemented by Victoria D, will also affect the baby's dimensional D reserve. If parents also ignore the additional supplement of cod liver oil, the child is more likely to have vitamin D deficiency. “If you want to prevent calcium deficiency, you should start supplementing cod liver oil 2-3 weeks after your baby was born, because this time the basic vitamin D brought from your baby's womb has basically run out.†Mai Yougang said, “In fact, after the mothers are pregnant, During the three months and during breast-feeding, cod liver oil should be properly supplemented, and attention should be paid to taking children out of the sun. At least half an hour to 1 hour is required for daily outdoor activity.†Appropriate calcium supplement after adding Food Supplement for 4 months The child grows up to 4 months old and begins to add complementary food. Due to the relatively small amount of calcium contained in food supplements, it is recommended that children at this age should make appropriate supplements to calcium tablets. Mai Yougang pointed out that for normal children, 1-2 tablets (about 50 mg) of calcium supplements are basically enough, and the rest is best supplemented by foods, such as allowing children to eat egg yolks, deep-sea fish, pig livers, etc. High-calcium foods, milk also insist on drinking. At the same time, vitamin D supplementation is still the same, eat 400 international units a day. However, the exception is for children who grow fast and have diseases (such as diarrhoea, infections, and malnutrition), because growing faster means more calcium and vitamin D, while having diseases means insufficient calcium intake and poor absorption. , If not targeted supplements under the guidance of a doctor, I'm afraid it will lead to calcium deficiency, or even cause other more serious complications. Mai Yougang also reminded that you should not equate your child with calcium deficiency and calcium deficiency. Accurately speaking, calcium deficiency can cause bones to be poorly calcified and cause "deformation". Not long ones may be related to insufficient energy supply and lack of growth hormone, and there may be diseases. The reasons for this are very complicated. It is recommended that you do a check first and do not blindly add calcium. What are the symptoms of calcium deficiency performance? The most common form of calcium deficiency in children is rickets. Rickets is due to poor bone calcification caused by vitamin D deficiency, mainly manifested as cranial, costal valgus, chicken breast, X-shaped leg or O-shaped leg. In general, there are not many patients who have reached this level of severity, mainly patients with mild rickets, which can be manifested as poor sleep, provocation, hyperhidrosis, and baldness at night. There are such symptoms to seek medical attention early, do not blindly calcium. Too much calcium can cause constipation, increase kidney burden and impair kidney function. If parents have concerns about their children, they can check whether they have caused adverse effects by checking blood and checking urine.
