What causes excessive amniotic fluid during pregnancy?

　　female During pregnancy, B-ultrasound indicates that if the amniotic fluid index (AFI) exceeds 18 cm, it can be judged as polyhydramnios. Of course, the amniotic fluid index is different in different trimesters. For example, it is mostly about 500cc during pregnancy, 300 to 400cc in the second trimester, and about 1,000cc in the third trimester. fetus The amount of amniotic fluid swallowed and the amount of urine excreted will affect the amount and composition of amniotic fluid, so under normal circumstances, as long as the examination does not reveal too much or too little, there is no need to worry.

　　What are the specific symptoms of polyhydramnios?

　　Pregnant women usually feel that their abdomen distended pain , in severe cases, symptoms such as shortness of breath and inability to lie down may occur. Abdominal examination will reveal tightness in the abdominal wall, skin It is shiny, the entire abdominal circumference, and the fundus of the uterus are larger than normal pregnancy. The fetal heartbeat cannot be clearly distinguished, and the fetal head has an obvious floating feeling.

　　Polyhydramnios is very dangerous

　　clinical The main symptoms of polyhydramnios are high blood pressure, edema, proteinuria, and in severe cases, convulsions, which threaten the normal development of the mother and fetus. Clinically there are many premature birth , umbilical cord prolapse, early placental separation, etc. are all closely related to polyhydramnios in pregnant women.

　　What are the causes of polyhydramnios?

　　The causes of polyhydramnios can be mainly divided into fetal causes and maternal causes.

　　Fetal factors: than the fetus nerve Tube malformations, fetal digestive tract malformations, excessive fetal urine, abnormal development of the urinary system, excessive fetal size, early fetal water rupture, poor fetal development, insufficient placental function, etc. It can be said that as long as the fetal own factors are one of the main reasons for polyhydramnios or too little amniotic fluid.

　　Maternal factors: Pregnancy-complicated diseases such as diabetes, high blood pressure, the mother's body being affected by hypovolemia, too little water absorption, or some other drugs may affect the amniotic fluid index of the fetus.

　　Therefore, for pregnant women, as long as polyhydramnios or too little amniotic fluid is detected, treatment and prevention should be carried out from these aspects. If there is acute polyhydramnios, or fetal malformation has been detected, it is recommended to terminate the pregnancy and end the pain as soon as possible.

　　What are the clinical methods to prevent and treat polyhydramnios?

　　If it is oligohydramnios, you should increase the amount of water you drink. If it is polyhydramnios, you should pay attention to reducing the amount of water you drink, lie down and rest more, pay more attention to ensuring a low-salt diet, pay more attention to observing the growth of the fetus at any time, pay attention to judge whether there are any abnormalities in the development of the fetus, and pay attention to whether the amniotic fluid index is within the normal range.

　　If everything in the fetus is normal and you want to keep the fetus, you can try amniocentesis decompression or prostaglandin synthase inhibitor treatment. If the problem causing polyhydramnios can be found, the amniotic fluid index can also be adjusted by treating the cause.

　　After going through the above treatment methods, you should pay attention to the treatment during the delivery period. You should pay attention to the method of artificial rupture of membranes as early as possible. If you are already in labor, you should pay attention to the use of uterotonic prophylaxis. Postpartum Heavy bleeding and so on.

　　For women during pregnancy, whether polyhydramnios or oligohydramnios will have a great impact on the life safety of the fetus and mother, it is recommended to check the amniotic fluid index for timely and scientific prevention and treatment.（99healthy Special article on the website (www.99.com.cn).
