During pregnancy, if a woman has low amniotic fluid, the following symptoms may occur: 1. the pregnant woman will feel pain during fetal movement, because the low amniotic fluid will limit the fetus’ range of motion, so there will be abdominal pain during fetal movement; 2. the pregnant woman’s stomach will be smaller, because the abdominal circumference and fundal height of the pregnant woman are related to the size of the fetus and the amount of amniotic fluid. If the amount of amniotic fluid is low, it will cause the abdominal circumference and fundal height of the pregnant woman to be smaller than the normal gestational months; 3. The pregnant woman will feel that the number of fetal movements is reduced or too frequent, because when the amount of amniotic fluid in the abdomen is low, it will cause the fetus in the abdomen to suffer from lack of oxygen, resulting in abnormal fetal movements. During pregnancy, if the above symptoms occur, women should be highly alert to the low volume of amniotic fluid caused by, should promptly go to the hospital to identify the cause of the disease, and then for treatment.
