Causes and manifestations of acute polyhydramnios

Prenatal check-up is an important policy advocated by the country to prevent various fertility problems. Hospitals have also invested a lot of advanced equipment in this regard. For expectant mothers and fathers who are about to give birth, the awareness of voluntarily participating in prenatal check-ups has gradually increased. These are conducive to the early detection of some diseases during pregnancy, such as acute polyhydramnios. So let's discuss this issue below and do some popular science.

When the amount of amniotic fluid exceeds 2000ml during pregnancy, it is called polyhydramnios. The incidence rate is 0.5% to 1%. A sharp increase in the amount of amniotic fluid within a few days is called acute polyhydramnios; a slow increase in the amount of amniotic fluid over a long period of time is called chronic polyhydramnios. When there is excessive amniotic fluid, the appearance and shape of the amniotic fluid are no different from those in normal cases.

1. Cause

According to statistics, the cause of more than 1/3 of polyhydramnios is unknown, which is called idiopathic polyhydramnios. 2/3 of polyhydramnios may be related to fetal malformations, pregnancy complications and complications.

1. Fetal malformation: about 1/4. The most common malformations are those of the central nervous system and digestive system.

2. Multiple pregnancy.

3. Placental and umbilical cord lesions.

4. The mother and child’s blood types are incompatible.

5. Diseases of pregnant women: diabetes, hypertension, acute viral hepatitis and severe anemia, etc.

2. Clinical manifestations

1. Acute polyhydramnios is less common. It usually occurs between 20 and 24 weeks of pregnancy. The amniotic fluid increases dramatically and the uterus enlarges significantly in a short period of time, producing a series of compression symptoms: abdominal distension, difficulty in movement; painful expression; difficulty breathing, cyanosis, and even inability to lie flat.

2. Chronic polyhydramnios is more common. It often occurs in late pregnancy. The amniotic fluid slowly increases over several weeks and the symptoms become milder. No obvious discomfort or only mild compression symptoms: chest tightness, shortness of breath, can be tolerated.

Through the above popular science information, regarding the problem of acute polyhydramnios in pregnant women, although the cause of more than 30% is unknown, it is still very important to discover this problem in time during the prenatal check-up. We need to pay attention to various clinical manifestations at all times. Once the problem of acute polyhydramnios occurs, we must go to a professional hospital for further examination in time and deal with it as soon as possible to avoid more serious situations.
