Causes of slow embryo development

Conceiving a baby is something that every woman both looks forward to and fears. With the opening of the second-child policy in the past two years, the number of new mothers has begun to increase, but not every woman can go smoothly from pregnancy to delivery. The human body is great and full of unknowns, especially the baby in the embryonic period. This is why every mother has to go for regular prenatal checkups to observe the baby's growth. Some babies may develop slowly or even stop growing. Do you know why?

Fetal growth process: After one month in the uterus, the fertilized egg begins to divide and proliferate, and implants in the uterus. The primitive forms of the organs begin to appear, and blood circulation begins to be established. The fetus is mainly differentiated in the first two months in the uterus. The face, limbs and fingers and toes begin to form. The heart and certain digestive organs develop rapidly. The amniotic cavity is formed, and the embryo lives in the comfortable amniotic fluid. After three months in the uterus, the reproductive organs of the fetus begin to differentiate, testicles appear in males and ovaries appear in females, the heart, brain, liver, and kidneys begin to move, and the limbs can make slight movements. The characteristics of the fetus are basically formed. During the 4 to 6 months in the uterus, the fetus increases rapidly in length and weight, each organ has certain functions, the limbs move more powerfully, the mother can feel the fetal movement, and the fetal heartbeat can be heard from the pregnant woman's abdomen. By the end of 6 months, the fetus can reach 30 cm in length and weigh about 1500 to 2000 grams. The fetus increases rapidly in length and weight during the 7 to 9 months in the uterus. Organ activity is further enhanced. After 10 months in the uterus, the fetus increases in length to about 50 cm and weighs 3000-3500 grams. Its skin is pink, subcutaneous fat is well developed, hair is about 2-3 cm long, nails extend beyond the fingertips, limbs are active, and it is able to survive outside the mother's body.

The causes of fetal growth retardation include: ① maternal factors, such as maternal malnutrition, picky eating, hyperemesis gravidarum, insufficient intake of protein and vitamins, smoking, drug abuse, mental stress, pregnancy-induced hypertension syndrome, pregnancy complicated by medical diseases, etc.; ② fetal factors, such as chromosomal abnormalities and fetal malformations, intrauterine viral infection, and multiple pregnancies; ③ placental factors, such as placental malformations, decreased placental function, umbilical cord that is too long or torsion and knotting, etc. In addition, pregnant women's exposure to harmful chemicals, X-ray radiation, and environmental pollution around their lives and work during pregnancy also have a certain impact.

Precautions for pregnant women during pregnancy: Pay attention to nutritional combination and have a balanced diet. Avoid eating irritating foods, such as spicy foods. Use less electronic products, reduce radiation, etc.......
