The best calcium supplementation time for pregnant women
Every pregnant woman needs calcium supplements. Because the calcium needed for fetal bone formation is entirely derived from the mother, the amount of calcium consumed by expectant mothers is much greater than that of ordinary people. It is not enough to rely on dietary calcium alone. How pregnant women supplement calcium has always been a topic of concern for every expectant mother.
Why do pregnant women need calcium?
According to the Chinese Dietary Nutrition Reference (DRI) formulated by the Chinese Nutrition Society, the standard supply of calcium for pregnant women in the early stages of pregnancy is 800 mg per day; in the second trimester, 1000 mg per day; and in the late pregnancy, 1200 mg per day.
The dietary habits of pregnant women, which are based on common foods, have only 400-700 mg of calcium per day, which is difficult to meet the supply standards. The hazard of calcium deficiency in pregnant women is very serious. First, it will cause maternal calf spasm, muscle twitching, pregnancy-induced hypertension, loosening of postpartum teeth, pelvic pain, joint pain, etc.; Second, it will affect the health of the fetus, resulting in incomplete fetal teeth, bone and osteoporosis, softening, blood Coagulation is not normal, congenital throat softening disease.
Is it good to start calcium supplementation in the first few months of pregnancy?
To understand the good start of calcium supplementation in the first few months of pregnancy, we must first understand the law of pregnant women's demand for calcium. In the early stages of pregnancy, the calcium requirement of pregnant women is about the same as that of normal people, so no special calcium supplement is needed. After 4 months of pregnancy, pregnant women's daily calcium demand gradually increased from 1000 to 1200 mg. At this time, the amount of calcium contained in our daily diet has failed to meet the baby's growth needs, so the remaining calcium needed to be taken from calcium-containing foods or high-quality calcium.
A few months of pregnancy start calcium supplementation, from the above analysis shows: pregnant women calcium supplement, not the sooner the better, nor the more the better. Under normal circumstances, calcium supplementation from pregnant women can start from the fourth month of pregnancy.
Of course, if the pregnant woman is pregnant, it may not be in the 4th month that there are obvious symptoms of calcium deficiency such as: leg cramps, loose teeth, pregnancy-induced hypertension syndrome, joints, pelvic pain, etc. If the pregnant woman has the above symptoms One, shows that pregnant women have calcium deficiency, but also need timely calcium.
How should calcium be added during pregnancy? Is the method of supplementing calcium normally correct?
One Note: The best calcium supplement time is before bedtime
Most people eat calcium tablets always follow the instructions on the calcium tablets instructions "take after meals." Chen Hao said that calcium is not ideal after a meal. The so-called "taking after meals" in the instructions is to avoid the stimulation of gastric mucosa by calcium tablets. Taking calcium tablets after meals, calcium combined with oils to form calcium soap can cause constipation. Combining with vegetables to form calcium oxalate, it is easy to form stones, which are not conducive to the absorption of calcium.
So when should you eat calcium tablets? Chen Yu introduced that the best calcium time is before going to sleep. Blood calcium levels are generally higher during the day and lower during the night. At night, especially in the middle of the night and early morning, low blood calcium levels can stimulate the secretion of parathyroid glands, accelerate the decomposition of bone calcium, produce decalcification, cause hypocalcemia, and cause severe convulsions.
Calcium supplementation before going to sleep can provide a source of calcium for calcium regulation at night, blocking the use of bone calcium in the body. And calcium is related to the stability of the autonomic nervous system, has a sedative effect, and helps sleep.
Two Note: It should not be light soup drink milk calcium
Many pregnant women do not know how much calcium should be eaten. Human nutrition clearly stipulates that 800 mg of calcium should be given in the first trimester of pregnancy and 1000-1200 mg in the second trimester, while in the third trimester it should be 1200-1500 mg and the maximum amount is 2,000 mg. The daily meals can only provide less than 400 milligrams of calcium. A cup of 250 ml of milk contains about 300 milligrams of calcium. Some pregnant women asked if they could drink two glasses of milk a day. "It's still best to have a cup of milk. Milk has a lot of lactose. Drink two cups of milk (500 milliliters). The total caloric intake is 270 kcal, which is more than 200 thousand daily increase for pregnant women." Cards, pregnant women will get fat, and the required calcium is still not enough."
Most people think that bone soup is the most calcium, so light soup does not eat meat. Chen Yu reminds you that: Calcium is far from enough! “Bone calcium is basically insoluble in soup. 1 kilogram of bone weighs 3-4 hours. 1 kilogram of bone soup contains only 20-50 milligrams of calcium. Tang Yuanyuan can not supplement calcium.†This means that relying solely on meals, soups and milk is far less than the demand for supplemental calcium, clinically found that osteomalacia, bone loss is very common, 70% -80% of mothers have light or heavy The performance of calcium (sleep awakening, muscle twitching, etc.) disappears through scientific calcium supplementation.
The concentration of sodium citrate required for the erythrocyte sedimentation test is 3.8%, and the ratio of anticoagulant to blood is 1:4. This is a special test tube for the erythrocyte sedimentation rate. The sample type is plasma, which is suitable for erythrocyte sedimentation. Immediately after blood is drawn, it is reversed and mixed 5-8 times. It should be shaken again when it is used. The difference between it and the test tube for coagulation factors is that the concentration of anticoagulant is different from the proportion of blood and cannot be confused.
