Amniotic fluid is the environment in which the fetus lives, and low amniotic fluid generally means that there is some abnormality in the fetus. Generally speaking, in a full-term pregnancy, an ultrasound indicates that the amniotic fluid index is less than 5 cm or the maximum amniotic fluid depth is less than 2 cm, which is called low amniotic fluid. Pregnant women should first check the cause of low amniotic fluid, except for the decrease in amniotic fluid caused by placental dysfunction, and also except for fetal urinary system developmental malformations. In the clear exclusion of fetal malformations, if the pregnant woman has too little amniotic fluid, can be supplemented by the following common methods: 1, diet: increase the amount of water, pregnant women need to take in about 1500ml of water per day, if the amniotic fluid is just low, then you can increase the amount of water through the daily soup, eat water-rich fruits and vegetables, such as watermelon, cucumber, cantaloupe, etc. to replenish the body water, increase the amount of amniotic fluid 2, increase exercise: choose soothing exercise, by accelerating the blood circulation of the whole body, is conducive to the production of amniotic fluid; 3, injection of amniotic fluid: when the amount of amniotic fluid is drastically reduced doctors can use professional instruments to inject saline directly into the amniotic cavity, thus alleviating the problem of low amniotic fluid within a short period of time; 4, intravenous infusion: mainly to increase the blood volume of pregnant women to improve the low amniotic fluid; 5, drug therapy: if the amniotic fluid is caused by If the amniotic fluid is low due to microcirculatory disorders in pregnant women, under the guidance of a doctor, you can apply drugs that unblock or improve microcirculation to increase the amount of amniotic fluid. If the fetal movement is too frequent or reduced, you must monitor the fetal heart rate and receive treatment in time. The woman should pay attention to rest, avoid strenuous exercise and collision with the abdomen, do not wear high heels to prevent falls.
