The normal range of amniotic fluid index at 24 weeks of pregnancy is 5-20cm, it is best to have regular ultrasound check, if it is higher or lower than this value is not normal. This may be caused by abnormal amniotic fluid, which may be a multiple pregnancy, fetal malformation, etc. It is best to have further ultrasound examinations to see how the baby is developing. If the baby is developing normally then there is nothing to worry about, but if the fetus is deformed it is best to go to the hospital to induce labor to avoid affecting the baby’s development after delivery. If the amniotic fluid is low, it is best to drink more water, and it is recommended to drink soy milk, etc., which can promote the increase of amniotic fluid. It is best not to overwork during pregnancy, do not eat spicy and stimulating food, do not contact with radiation, do not take drugs, etc., to avoid causing fetal malformations.
