Late pregnancy amniotic fluid stomach distension needs etiologic treatment, drug treatment, amniocentesis to release amniotic fluid, termination of pregnancy, and so on. 1. Etiological treatment: when the ultrasound examination of amniotic fluid, to actively etiological treatment, the most common is combined with gestational diabetes, maternal hyperglycemia will lead to increased fetal blood glucose, which produces hyperosmolar diuresis, making the amniotic fluid increase. Need under the guidance of the doctor strict diabetic diet, and appropriate exercise to control blood glucose, if necessary, need insulin therapy. 2. Drug therapy: indomethacin antidiuretic treatment can be given under the guidance of a doctor before the 32nd week of pregnancy, which can inhibit fetal urination and reduce amniotic fluid, and weekly ultrasonography to monitor the amount of amniotic fluid during the period of medication. 3. Amniocentesis to release an appropriate amount of amniotic fluid: when the symptoms are serious, the doctor can release an appropriate amount of amniotic fluid through the abdominal wall amniocentesis to relieve the symptoms, but also to closely observe the pregnant woman’s blood pressure, heart rate, respiration, and changes in the fetal heart. If necessary, amniotic fluid can be released again in 3~4 weeks to reduce the pressure in the uterine cavity and relieve the symptoms. 4. Termination of pregnancy: When the amount of amniotic fluid increases repeatedly and the symptoms are serious, the pregnancy can be terminated when the pregnancy is ≥34 weeks, and when the fetal lungs are immature, termination of pregnancy should be considered after promoting the maturation of the fetal lungs.
