Fetal movement usually appears from 18-20 weeks of pregnancy, if earlier than 18 weeks, no fetal movement throughout the day is usually normal, can wait for the fetal development to 18 weeks and then observe; if 18 weeks of pregnancy only after no fetal movement, need to pay attention to whether caused by the following reasons: 1, pregnant women abdominal fat is too thick: if the pregnant women abdominal fat layer is thick, coupled with the fetal movement is slight, may make pregnant women think there is no fetal movement; 2, fetal distress: maternal blood oxygen deficiency, poor placental function or umbilical cord bypass and other factors lead to fetal hypoxia. The fetus is in intrauterine distress: insufficient maternal blood oxygen, poor placental function or umbilical cord encirclement and other factors lead to fetal hypoxia, making fetal movement abnormal. With the aggravation of hypoxia fetal movement can be reduced or even stopped; 3, fetal development stop: due to the influence of factors such as embryonic chromosomal abnormalities or poor maternal uterine cavity environment, it may cause the fetus to stop developing, thus not feeling fetal movement. During pregnancy, attention should be paid to the reasonable intake of nutrients, and the intake of vitamins and proteins can be increased appropriately to maintain the normal growth and development of the fetus. Pay attention to avoid overeating to avoid increasing the risk of gestational diabetes and gestational hypertension. In addition, pregnant women can count the fetal movement during pregnancy, and if there is any abnormality, they should seek medical attention in time to improve the relevant examination and give appropriate treatment and handling measures.
