Does the fetus with 27 weeks pregnancy have the best calcium supplement effect? First of all, it is necessary to determine whether the fetus at 27 weeks of pregnancy is too small because of calcium deficiency, or it may be caused by other reasons. If it is determined that it is caused by maternal calcium deficiency, it is necessary to supplement calcium in time. So what is the effect of calcium supplementation?
1, green leafy vegetables
Vegetables not only contain a lot of potassium and magnesium, but also help maintain acid-base balance and reduce calcium loss, such as small rapeseed, Chinese cabbage, kale and celery. According to recent research, vitamin K in green leafy vegetables is the formation factor of osteocalcin, which is necessary for calcium deposition in bones.
2. Sesame
Sesame paste is also a very good calcium supplement food, and its calcium content is not inferior to cheese. Sesame itself has a hard shell, and the digestibility of nutrients is relatively low. But after grinding into sesame paste, the digestibility will be greatly improved, and sesame paste is delicious. Eating 1 tablespoon sesame paste can contain about 200 mg of calcium.
3. Dairy products
Half a catty of milk contains 300 mg of calcium, and also contains a variety of amino acids, lactic acid, minerals and vitamins, which can promote the digestion and absorption of calcium, so milk is the best calcium supplement food. As the most easily absorbed calcium source, milk can be used as the main food for daily calcium supplementation.
4, kelp and shrimp skin
Kelp and shrimp skin are also high-calcium seafood. As long as you eat 25 grams a day, you can supplement 300 milligrams of calcium, reduce blood lipids and prevent arteriosclerosis. However, shrimp skin contains trace amounts of nitrosamine carcinogens, which should be eaten in moderation.
Don't worry too much about how the biparietal diameter of the fetus is too small at 27 weeks of pregnancy. The small fetus may also be due to the inaccurate holiday cycle, and the result of BC will be small. Usually pay attention to eat more nutritious food and corn and sweet potatoes.
Double crown diameter is also called BPD, and double crown diameter of fetal head. Refers to the length of the widest part between the left and right sides of the fetal head, also known as the "large transverse diameter of the head". Doctors often use it to observe the child's development and judge whether there is an imbalance between the head and pelvis and a natural delivery.
The biparietal diameter of the fetus should reach 9.3 cm or more at full term. According to the general rule, after 5 months of pregnancy, it basically coincides with the month of pregnancy, that is, the BPD of 28 weeks (7 months) is about 7.0 cm, and that of 32 weeks (8 months) is about 8.0 cm, and so on. After 8 months of pregnancy, it is normal to grow about 0.2 cm per week on average. When the expected delivery date cannot be determined by CRL in the early stage, BPD is often used for forecasting; After the middle period, it is often necessary to measure these data when estimating fetal weight.
Experts remind: it is not scientific enough to see whether the fetus is male or female with double top diameter. But the fetal weight is calculated by biparietal diameter examination, and the formula is: fetal weight = biparietal diameter *900-5200 (g).
Femoral length (FL) is a commonly used index for doctors to observe fetal development when using B-ultrasound (or color ultrasound) to examine pregnant women during pregnancy.
Femur and humerus are both typical long tubular bones in human body, which are divided into two ends. The femur is the largest long bone in the human body, which refers to the thigh bone; The humerus is located in the upper arm, also known as the upper arm bone. So as the name implies, the length of femur is the length of femur, and the length of humerus is the length of upper arm bone.
Femoral length and humeral length are both fetal biological indexes to predict fetal weight. However, fetal humeral length is superior to femoral length in predicting fetal weight.
