Amniotic fluid is closely related to the health of the baby and mother, and the amount of amniotic fluid can affect the health of the fetus and mother to a certain extent. At 33 weeks of pregnancy, it belongs to the late stage of pregnancy. At this time, some pregnant mothers may experience a shortage of amniotic fluid. So, what is the reason? What are the symptoms of oligohydramnios? Let's take a look.
What are the reasons for oligohydramnios at 33 weeks of pregnancy
Firstly, amniotic membrane rupture leads to oligohydramnios. Even a small tear on the amniotic membrane can cause some amniotic fluid to flow out. This situation may occur at any stage of your pregnancy. However, it is more common near production. If you notice that your underwear is wet, you will notice that your amniotic fluid is leaking; Or when the doctor performs an examination on you, it may also be discovered.
Secondly, placental issues lead to insufficient amniotic fluid. If there is a problem with the placenta, such as partial abruption, the placenta cannot provide sufficient blood and nutrients to the baby, leading to the interruption of amniotic fluid circulation in the fetus.
Thirdly, certain disease factors can lead to oligohydramnios. Some diseases can also lead to oligohydramnios, such as chronic hypertension, preeclampsia, diabetes and lupus.
What are the symptoms of oligohydramnios
Firstly, during fetal movement, pregnant women may feel significant abdominal pain; Placental dysfunction often results in reduced fetal movement.
Secondly, the uterus is sensitive, and slight stimulation can easily cause contractions.
Thirdly, during prenatal check ups, it can be found that the pregnant woman's uterine height and abdominal circumference are both smaller than the gestational age, and the fetal movement is more restricted, resulting in a feeling of tight wrapping of the uterus around the fetus.
Fourthly, there is obvious labor pain after delivery, and most contractions are not coordinated. When conducting a vaginal examination, it may be found that the anterior amniotic sac is not obvious, the fetal membrane is tightly attached to the exposed part of the fetus, and there is very little amniotic fluid leakage during artificial rupture.
In summary, there are various and complex reasons for oligohydramnios. Oligohydramnios can affect delivery and even lead to difficult labor. Therefore, expectant mothers must take it seriously, communicate more with doctors, regularly check their bodies, understand their own health status and the health status of their babies, and take relevant preventive measures.
