Amniotic fluid is produced on the 8th day after fertilization, and as the gestational week increases, amniotic fluid is slowly produced during the process, reaching 800-1000 ml at full-term gestation. early gestation amniotic fluid is produced through epithelial secretion of the amniotic membrane and amniotic transit, and as the gestational week increases, fetal urine becomes the main source of amniotic fluid after mid-gestation, and as the amniotic membrane slowly increases in size, by late gestation The fetal lungs are involved in the production of amniotic fluid, with approximately 350 ml of fluid secreted daily from the alveoli to the amniotic cavity. The amount of amniotic fluid needs to be closely monitored during pregnancy to determine whether it is normal or not. If the amniotic fluid volume is abnormal, it may indicate fetal hypoxia, and the fetal heartbeat and fetal movement need to be monitored to determine if the fetus is developing normally. If the amniotic fluid volume is too much, the pregnant woman should pay attention to monitoring her blood sugar, drink less water and exercise properly; if the amniotic fluid is too little, you can replenish it by drinking more water and infusion to maintain the normal development of the fetus. In daily life, pregnant women should pay attention to a light diet, avoid staying up late and overworking, and should maintain a moderate amount of exercise and sufficient sleep to promote the development of the fetus in the body.
