Low water - a rare anomaly of pregnancy
- water shortage - a rare anomaly pregnancy
Amniotic fluid is a part of the child's life support systems.It protects and assists in the development of muscles, limbs, lungs and digestive system.Amniotic fluid begins to produce shortly after the amniotic sac is formed, that is, approximately twelve days after conception Conception, ovarian cycle, fertilization and genetics baby .First, it consists of water coming from the mother, and then, about the twentieth week, it becomes a major constituent of fetal urine.In the second trimester, the baby starts to breathe and swallow amniotic fluid.Sometimes the level of the amniotic fluid is too low or too high.
There are several different methods for determining the level of amniotic fluid, but more often it is done with the help of the amniotic fluid index.
Low levels of amniotic fluid occurs in approximately 8% of pregnant women (compared to an increased level of amniotic fluid detected in 4% of women).Water shortage may develop at any time during pregnancy, but most often it happens during the last trimester.The risk of water scarcity increases dramatically if the pregnancy lasts longer than the estimated life.Water shortage causes complications about 12% of pregnancies that lasted more than 41 weeks.
reasons for water scarcity
- Birth defects - problems with the development of kidney and urinary tract that can cause reduced production of urine,This in turn leads to low amniotic fluid.
- Placental problems - If the placenta does not provide the baby with enough nutrients, processing fluid in the body of the child can be broken or completely stop.
- rupture of membranes may cause both rapid outflow of fluid and its slow leak.Premature rupture of membranes can also lead to a decrease in the level of amniotic fluid.
- excess of pregnancy, especially for more than two weeks, as is the cause of water scarcity.
- maternal complications, such as dehydration, hypertension Hypertension - dangerous consequences , pre-eclampsia, diabetes and chronic hypoxia, can lead to a reduction in amniotic fluid.
The dangerous oligoamnios
Risks associated with oligohydramnios, often depend on the duration of pregnancy.Amniotic fluid is essential for the development of muscles, limbs, lungs and digestive system.In the second trimester, the baby begins to breathe and swallow amniotic fluid, which contributes to the growth and strengthening of the lungs.Amniotic fluid also helps to develop the child's muscles and limbs, providing plenty of room to move.The most serious complications may, if oligohydramnios develops in the first half of pregnancy.Among these complications:
- Compression of fetal organs, and as a result, birth defects;
- increased risk of miscarriage Miscarriage - whether it can be insured? or stillbirth.
- Possible complications of oligohydramnios in the second half of pregnancy:
- intrauterine growth restriction;
- Premature birth;
- Various complications during childbirth, which can sometimes lead to forced cesarean section.
choice of treatment when oligohydramnios mainly depends on gestational age.If you have not yet reached full-term pregnancy, the doctor will carefully monitor your condition;but otherwise it is often recommended to artificially induce labor.
During delivery liquid to fill the amniotic fluid can be introduced through the intrauterine catheter - it helps reduce the risk of situations in which it may be necessary cesarean section.
