General food can not play the role of long amniotic fluid, pregnant women in the late stages of pregnancy if there is too little amniotic fluid, you need to terminate the pregnancy in time to take Caesarean section. Low amniotic fluid is the amount of amniotic fluid less than the expected value of the corresponding gestational age, such as less than 300ml of amniotic fluid in late pregnancy, low amniotic fluid seriously affects the prognosis of the fetus. Its etiology is complex and varied, and may be caused by fetal structural abnormalities, placental hypoplasia, amniotic membrane pathology, and maternal blood volume insufficiency. As food does not have any efficacy or effect, usually eating does not work to increase amniotic fluid. Pregnant women can drink more water appropriately on a daily basis. If the amniotic fluid is low and the pregnant woman’s pregnancy has reached 36 weeks and the fetal lungs have fully matured, the pregnancy can be terminated, and cesarean section can be performed. If low amniotic fluid is combined with fetal malformation, the patient needs to be injected with isacridine via amniocentesis under ultrasound guidance so as to induce labor. Pregnant women with low amniotic fluid should go to regular hospitals to undergo relevant examinations to find out the growth and development of the fetus and cooperate with doctors to take therapeutic measures.
