When is vitamin ae examination for pregnant women done? This kind of examination can not be used as a routine examination during pregnancy, but it can still be done if conditions permit.
If all the tests are normal after pregnancy and there is no abnormal vaginal bleeding, it is not necessary. Vitamin AE is essential for pregnancy. I suggest you eat folic acid on time, strengthen nutrition, have more rest, and don't fry greasy, spicy and irritating foods. There is no need to do it without exception.
There is no need to do routine examination of vitamin AE in the second trimester, just pay attention to a balanced diet and nutrition. There is no routine examination of vitamin AE in the second trimester, so eat more foods containing vitamin AE. During pregnancy, we must pay attention to a happy mood, moderate exercise, regular work and rest, and balanced nutrition.
It is recommended to do it in the first trimester. This examination is a routine examination of pregnancy test, which is to detect the contents of vitamins A and E in pregnant women. Lack of vitamins A and E in the body is very harmful, which not only affects pregnant women, but also affects the development of the fetus. In addition, it is suggested to actively supplement sufficient folic acid in the early pregnancy, pay attention to moderate exercise, pay attention to diet, eat more fresh vegetables, fruits, bean products, lean meat, fish, chicken and other foods, and pay attention to pregnancy tests on time.
Generally speaking, after a woman is pregnant, the body's demand for nutrients will continue to increase. If a pregnant woman lacks vitamins, there will definitely be some symptoms corresponding to vitamin deficiency. For example, she lacks vitamin D during pregnancy, and pregnant women are prone to leg cramps due to calcium deficiency. So if conditions permit during pregnancy, she can go to the hospital for a check-up. However, the normal diet of pregnant women can maintain a balanced nutrition, and the lack of vitamins can be said to be minimal.
What is the purpose of checking vitamin ae during pregnancy? Lack of vitamin A in expectant mothers will lead to skin thickening, epithelial dryness, hyperplasia and keratinization, and may also cause symptoms such as abortion, embryonic hypoplasia or fetal growth retardation. When it is seriously lacking, it will also cause fetal malformation.
Lack of vitamin E in early pregnancy can lead to congenital malformations of infants, such as encephalocele, anencephaly, scoliosis, umbilical hernia, toe deformity and cleft lip, and also lead to low birth weight of infants. In addition, some studies believe that the lack of vitamin E in pregnant women can easily lead to anemia in infants.
Lack of vitamin D in pregnant women may lead to calcium deficiency in the fetus. Will affect the growth and development of fetal bones. Rickets may occur at birth and develop into rickets in childhood, leading to a series of adverse conditions such as bone softening, fracture and bone deformation, growth retardation, physical pain, physical weakness and so on. Therefore, after three months of pregnancy, pregnant women need to supplement calcium regularly, and at the same time, properly bask in the sun to promote the absorption of calcium, drink more high-calcium milk at ordinary times, and have a comprehensive and diversified diet to avoid picky eaters and partial eclipse.
Vitamins A and E have important effects on lung development, brain development, physical development and immunity of fetuses and children's offspring. MVAD will lead to fetal rat lung hypoplasia and structural disorder, and with the passage of time, this difference will become more and more significant, eventually leading to uneven atelectasis (atelectasis) and excessive expansion of the lung (emphysema), and the total compliance of the lung will decrease. At the same time, vitamin AE deficiency affects brain development, learning and memory, spinocerebellar ataxia, brain enlargement and deformation, and inhibits the expression of nerve growth factor. Excessive vitamin AE can damage fetal cognitive function, neuronal malformation, and so on.
The imbalance between vitamins A and E will also have an important impact on spontaneous abortion, premature delivery, premature rupture of membranes, anemia during pregnancy and hypertension. The imbalance of vitamin A and vitamin E, the decrease of antioxidant effect, is not enough to resist free radical damage, affect DNA modification and protein synthesis, and endanger embryo development, thus causing spontaneous abortion, premature delivery and premature rupture of membranes. At the same time, vitamin A affects iron metabolism and hemoglobin synthesis, leading to anemia in pregnant women. If vitamin A is not corrected, anemia will be difficult to improve, and so on.
