- Low water - a rare anomaly of pregnancy
What are the amniotic fluid
Amniotic fluid surrounds the developing fetus, along with the fruit they are enclosed in the amnion (periconceptional bag). Using amniotic fluid all metabolic processes occurring between the pregnant woman and fetus, ensuring its growth and development. The amniotic allocated and all metabolites fetus (urine, mucus, exfoliated superficial layers of the skin and so on). In the amniotic fluid the fetus is in limbo, which protects it from external physical influences. When it is time delivery, amniotic fluid under pressure to the cervix and cause to unfold.
The amniotic fluid contains proteins, free amino acids (and their degradation products, e.g., urea), hormones, minerals, vitamins and enzymes.
In the first six weeks of pregnancy, amniotic fluid is very small, but over time, their volume increases and 38 weeks is about one and a half liters. In the next two weeks, the amniotic fluid becomes smaller (about 600 ml) - a sign that will soon begin delivery.
What malovidie and its causes
Water shortage - a small amount of amniotic fluid (less than 500 ml). Water scarcity is rare (3-4 cases per 1000 births). The causes of water scarcity are not fully understood. Typically, water scarcity due to insufficient development of the epithelium lining the inner surface of the amnion or decrease its secretory capacity.
In most cases, water scarcity develops in prolonged pregnancy. Often it develops in one of the identical twins

when polyhydramnios another, due to the uneven distribution of the total circulating in placenta blood. Such a condition can occur in chronic diseases, after an infection, metabolic disorders

and hormonal levels, smoking, alcohol abuse, as well as gestosis (late toxicosis of pregnancy). Water scarcity can lead to stunted growth and development of the fetus.
Signs of water scarcity
With a significant oligohydramnios in women may appear weak, aching pain in the abdomen
Abdominal pain: when to sound the alarm?
, Dry mouth, nausea
Nausea - there may be problems with the nervous system
When oligohydramnios often have spontaneous abortions and premature births. Pregnant experiencing pain during movement of the fetus. During labor, contractions are painful and ineffective, cervical dilatation is slow. Childbirth is prolonged, at the opening of membranes follows only a little thick, viscous, colored meconium (fetal feces) liquid.
After twenty weeks of pregnancy, the baby starts to move a lot and if the amniotic fluid is small, then they lose their cushioning function, whereby the child may get injured. Furthermore, a stay in a relatively stationary state may contribute to violations of the spine and the large joints (mainly the hip). It is also possible merging of the fruit with the amnion and education had malformations. The fetus suffers from a lack of oxygen that can cause disorders of the central nervous system, so often for health reasons such women performed caesarean section. Water shortage contributes to low birth weight and insufficient and vitality.
The diagnosis is made by water scarcity was insufficient (compared to the normal for the period) the size of the uterus, its thick consistency, limited mobility of the fetus. Confirmed diagnosis of fetal ultrasound (including ultrasound Doppler study of blood flow in the arteries of the uterus, umbilical cord and brain of the fetus). ALWAYS cardiotocography (CTG) - Simultaneous recording fetal heart rate and uterine contractions, which gives an indication of the health of the fetus.
How to treat oligohydramnios
After identifying oligohydramnios pregnant women prescribed drugs that improve blood circulation and metabolism in the placenta. If, despite treatment, the child's condition is not improving (according to ultrasound and CTG), then a sufficient gestation performed cesarean delivery.
Pregnancy at oligohydramnios usually ends successfully in cases where there is a woman doctor regularly and get timely adequate treatment.
