Causes of amniotic fluid during pregnancy

Amniotic fluid is an excess accumulation of amniotic fluid that exceeds the normal amniotic index. Although amniotic fluid is extremely important for fetal development, an excess of amniotic fluid can pose a number of risks and affect maternity and pregnancy.

1. Amniotic fluid function

The amniotic sac is produced about the 12th day after fertilization of the egg. In the first quarter of pregnancy, amniotic fluid issential and similar to the mother's plasma. In the second and second quarters of pregnancy the amniotic fluid becomes debilitating.

The volume of amniotic fluid gradually increases until the beginning of the last 3 months of pregnancy and from there it is determined until the full month of pregnancy. During the 37th to 41st week, the volume of amniotic fluid decreases by 10%. From the 42nd week er, the volume of amniotic fluid decreases very quickly, about 33% in a week.

2. What is amniotic fluid?

Amniotic fluid residue or amniotic fluid disorders are conditions where too much amniotic fluid forms during pregnancy. Amniotic fluid is now a fairly common condition. Amniotic fluid is considered normal when reaching 250 -600 ml at the age of 16-32 weeks. The amount of amniotic fluid increases with gestational age and by about the 34th week of pregnancy the amniotic fluid will reach 800ml and remain until the 36-week-old fetus will reach a peak of 1000ml. After that, it will gradually decrease to about 600 – 800ml around the time before birth. Pregnant women have amniotic fluid when the amount of amniotic fluid exceeds over 2000ml.

To diagnose multiple amnioticfluid, the doctor will perform an ultrasound and take the results of an indirect estimate of the volume of amniotic fluid. The mother was diagnosed with amniotic fluid index (A.F.I) through an ultrasound of 12-25cm . Most amniotic fluid is more than 25 cm.

3. Consequences of multiple amniotic fluid

Too much amniotic fluid can cause the mother's uterus to become tense and lead to premature birth or rupture of the amniotic membrane early (amniotic sac). Multiple amniotic fluid is also associated with birth defects in the fetus. When the amniotic fluid sac ruptures, a large amount of fluid fluid re-stagnant the uterus can increase the risk of placenta peeling (premature detaching) or umbilical cord prolapse (when the umbilical cord falls through the cervical hole).

Multiple amniotic fluid makes the fetus easily rotate because there is a lot of amniotic fluid around. This means that you have a fairly high risk of inverted birth. Most cases of multiple amniotic fluid are mild and due to the gradual accumulation of amniotic fluid in the second half of pregnancy. Severe amniotic fluid can cause shortness of breath, premature birth or other signs and symptoms.

If you are diagnosed with multiple amniotic fluid, your doctor will carefully monitor your pregnancy to help prevent complications. The doctor will treat depending on the severity of the disease. Mild amniotic fluid can be cured on its own. Severe amniotic fluid requires treatment, such as drainage of excess amniotic fluid.

4. Causes of amniotic fluid during pregnancy?

Amniotic fluid is the fluid that surrounds and buffers the fetus inside the uterus, which comes from the baby's kidneys and into the uterus from the baby's urine. Fluid is absorbed when the baby swallows and through breathing movement.

The amount of epidemic increases until the 36th week of pregnancy, then gradually decreases. If the fetus produces too much urine or does not swallow enough, amniotic fluid accumulates and causes multiple amniotic fluid. Sometimes doctors can't figure out the cause of multiple amniotic fluid. Factors related to amniotic fluid include:

  • Diabetes during pregnancy
  • Gastrointestinal abnormalities prevent the ingestion of amniotic fluid
  • Abnormal swallowing due to problems with the central nervous system or chroma abnormalities
  • Twin Blood Transfusion Syndrome
  • Heart failure
  • Congenital infection (acquired during pregnancy).

4.1 Who often suffers from multiple amniotic conditions?

Multiple amniotic fluid can affect people of all ages. You can control this disease by minimizing risk factors. Refer to your doctor for more details.

4.2 What factors increase the risk of multiple amniotic conditions?

There are many risk factors for multiple amniotic fluid such as:

Multiple pregnancies

Multiple pregnancies increase the risk of multiple amniotic fluid
  • Congenital malformations of the brain and spine
  • Obstruction of the digestive system
  • Genetic problems (problems with herededable chroma).

4.3 What are the signs and symptoms of amniotic fluid residues in pregnant women?

Mild amniotic fluid is usually asymptoatic. However, each woman may experience different symptoms. Symptoms may include:

  • The abdomen is larger than gestational age, it is difficult to hear the gestational heart rate.
  • The measurement of the abdominal ring (through the navel) is greater than 100cm, the abdomen is glossy, abdominal pain, shortness of breath, ingestion eating, breathing is also more difficult.
  • Dilated veins can lead to hemorrhoids during pregnancy.

Usually the pregnant mother will have an amniotic fluid at the 30th week, however there are also some pregnant mothers who have an amniotic fluid at the 20th week of pregnancy.

You may experience other symptoms that are not mentioned here. If you have any questions about signs of illness, consult your doctor.

4.4 When do you need to see a doctor?

You should contact your doctor if you have the following symptoms:

  • Shortness of breath
  • Abdominal pain
  • Abdominal obstruction

If you have any of the above signs or symptoms or have any questions, please consult your doctor. Each person's location is different, so consult a doctor to choose the most appropriate option.

3 months between pregnancy is a period of strong development of the fetus and prone to multiple amniotic fluid, for the prevention of multiple amniotic fluid and timely treatment, the pregnant woman needs:

  • Comprehensive fetal malformations screening using superior 4D ultrasound techniques.
  • Screening for gestational diabetes, avoiding causing many dangerous complications for both mother and baby.
  • Control the mother's weight appropriately to assess the state of health of the pregnant woman and the development of the fetus.
  • Understand the signs of premature birth (especially in people with multiple pregnancies or a history of miscarriage, premature birth) for timely pregnancy therapy.

To protect mothers and babies during pregnancy, Share99 provides a full maternity service to help monitor the health status of pregnant women comprehensively. With the above examination package, mothers are periodically examined with leading obstetrician, perform a full range of tests, important screenings for obstetrics and gynecology, consult and intervene promptly when detecting abnormalities in the health of mothers and babies. From there, it is intended to intervene promptly, avoiding the health effects of mothers and babies.
