- Water shortage during pregnancy - to which it can lead?
- Amniotic fluid, their composition and functions
During pregnancy, the baby is in a liquid-filled cavity, called the amniotic sac. The walls of the amniotic sac consisting of two membranes - chorion and amnion. Before birth, they are broken and the amniotic fluid flows out - this is called a withdrawal of amniotic fluid.
Amniotic fluid serves several important functions:
- Protect the child from various damages, for example, in cases where a pregnant woman is hit in the stomach or other injuries.
- It helps develop the baby's lungs and digestive system.
- To protect the child from infection.
The child regularly ingests a certain amount of amniotic fluid, and it is derived from the mother's body in the form of urine. Thus, the level of the amniotic fluid varies daily.
The amount of amniotic fluid increases with pregnancy. Of only a few milliliters in early pregnancy, it increases to 800-1000 ml of the thirty sixth week of pregnancy. Since the thirty-eighth week it gradually decreases, and so it goes up to the birth. A condition characterized by too small amount of amniotic fluid is called oligohydramnios. An excess of amniotic fluid is called polyhydramnios.
How is oligohydramnios?
The doctor may suspect oligoamnios if, according to the ultrasound, body length and weight of the child is too small compared with the average for a given gestational age.
Increased likelihood of water scarcity in women who have faced such violations during a previous pregnancy and / or who have had babies whose weight was below normal. Such women and expectant mothers, who have disorders of blood pressure, lupus and other diseases, further examined to identify water scarcity.
During the ultrasound measure the depth of the four pockets of amniotic cavity and folded the values obtained, calculate the amniotic fluid index (AFI). Each week of pregnancy corresponds to a certain index AFI. Slight variations are allowed, however, a big difference from the norm indicates the presence of a problem.
Causes of water scarcity
In addition to the withdrawal of amniotic fluid, can cause oligohydramnios:
- Problems with the placenta
- Medications taken by the expectant mother
- Health problems in the child
The withdrawal of amniotic fluid
Water may be varied rapidly, directly and in large volumes, and can be - very slowly, gradually. Sometimes they can be mistaken for an episode of urinary incontinence which is often observed in the later stages of pregnancy.
If you suspect that your water breaks, but are not sure, contact a doctor in. If this happens too early, you will probably be discharged medication to prevent infection. Depending on the duration of pregnancy after the withdrawal of amniotic fluid doctor may suggest that you call the birth with the help of drugs, or to wait a bit. In the latter case, the child should be checked regularly before birth will start naturally.
Problems with the placenta
Water shortage can be caused by a condition in which the placenta can not provide the child with enough blood and nutrients. This happens, for example, lupus, high blood pressure, pre-eclampsia and diabetes. The poor functioning of the placenta will inevitably affect the development of the child. If such violations doctors constantly monitor the health of mothers and children and sometimes designate special treatment.
Some drugs may cause oligohydramnios. Among these angiotensin-converting enzyme (ACE) inhibitors - drugs used to treat high blood pressure
Blood pressure - dangerous if his swing?
And nonsteroidal anti-inflammatories such as ibuprofen
Ibuprofen: anti-inflammatory drug
. Typically, these drugs are not appointed during pregnancy.
Health problems in the child
Low amniotic fluid can be related to the fact that the child's body does not produce or urine to pass in sufficient quantity. This may be a sign of its existing disorders of the kidneys, heart, or chromosomal abnormalities.
