Amblerous waters and their possible pathologies
Amniotic fluid (amniotic fluid)ensure the normal development and formation of the fetus throughout the pregnancy. Their composition is very diverse: proteins, fats, carbohydrates, vitamins, salts, hormones and other substances useful to the child. The fetus is formed at week 8 of pregnancy and increases as the child develops. The baby himself feels favorable only if the mother has a norm of amniotic fluid.
Their number corresponds to a certain periodpregnancy. So, at the 10th week they should be 30 ml, 14 - 100 ml, 18 - 400 ml, and 38 - 1000 ml. After 38 weeks, the amount of amniotic fluid begins to decrease, reaching about 800 ml before delivery. If the woman paces the time, the volume can reach 500 ml, and this figure is critical, because an insufficient amount of this liquid can cause problems during childbirth.
With ultrasound examination regularlydetermine the amount of amniotic fluid. Their norm, as stated earlier, correlates with the period of pregnancy. At an early stage of fetal development, the color of the amniotic fluid is transparent and similar to the coloration of human blood plasma. This similarity exists, because the amniotic fluid is just formed from it: the blood is filtered by the amniotic epithelium.
In later terms, when it developsthe urinary and respiratory system of the child, the color changes: the amniotic fluid acquires a cloudy color, because the sebaceous glands begin to function. Also, they begin to contain particles of the baby's epithelium, villi, elements of original grease.
The amniotic fluid is refreshed every three hours. It passes through the fetal body, removing the products of metabolism. Until the 23rd week of pregnancy, this process is carried out through the skin.
One of the important components of amniotic fluidis the urine of the fetus, which the kidneys begin to produce very actively at the end of pregnancy. By the time its amount is 600-800 ml per day. So, from the moment when the formation of the kidneys ends, the fetus itself begins to actively produce amniotic fluid.
Sometimes there are situations when amniotic fluid is produced in insufficient quantities. Then there is the development of hypohydrate, which can have the following reasons:
- Hypertension in the mother.
- Infectious diseases of the pregnant woman, which cause a lack of water in 40% of cases.
- Inflammation of female genital organs.
- Violation of the kidneys in the fetus.
- Metabolic disorders in the mother.
Malignant can develop at the initial stagepregnancy and often remains unrecognized. The main symptom is pain in the abdomen, which can significantly increase when the fetus moves.
Treatment of lack of water as such is not carried out. All the efforts of doctors are aimed at preventing possible pathology of the fetus. A control over the water is carried out using ultrasound.
Amelong water can be produced abovepermissible norm. This phenomenon is called polyhydramnios and is more common than the opposite. Symptoms of it are weight in the lower abdomen, pain, general malaise and swelling of the legs. In this connection, the blood circulation of the pregnant woman, her breathing and the functionality of certain organs are disturbed. The fetus actively begins to swim in the amniotic fluid, as a result of which the umbilical cord can encircle the neck and body. If the doctor suspects polyhydramnios, ultrasound is prescribed, diagnosis for intrauterine infection and malformations of the child is performed.
As a conclusion, we note that the lack of water as wellnegatively affects the fetus, as well as polyhydramnios. Ultrasound diagnostics makes it possible to recognize similar pathologies at early stages of development and to preserve the health of the mother and her child.
