Low placentation in pregnancy: what is it?
As a rule, the placenta is attached in close proximity to the bottom (the highest point) of the uterus, since it is here that the most favorable conditions for its normal functioning are created, in particular, the blood flow in the vessels is perfectly adjusted. Normally located is the placenta, formed at a distance of at least 6 cm from the uterine throat.
Cases when the placenta is formed in the lower part of the uterus, called low placentation. This happens if the egg is inserted into the lower part of the uterine walls.
Causes of low placentation in pregnancy
Experts call several reasons why the placenta in a pregnant woman may be low lying. One of them lies in the anatomical features of the organs of the reproductive system of women. To contribute to this can be both congenital pathologies (physiological anomalies), and acquired due to the impact of negative factors. Low placentation may be a consequence of past inflammatory processes, sexual infections and vascular diseases of the pelvic organs, or surgical interventions in the field of gynecological organs. In the risk group for the formation of low placentation are also pregnant women of advanced age.
Placentation is most common in women who give birth not to the first child. Notice this when carrying out an ultrasound. The position of the uterus is constantly diagnosed by physicians. In particular, ultrasound is done - in 16, 24-26 and at 34-36 weeks, can also carry out dynamic echographic research.
What is dangerous is low placentation
Because the placenta is close to the pharynx, it partially, and sometimes even completely - blocks the opening. As a consequence, there is a risk of bleeding, detachment of the placental coat and miscarriage.
The low placenta can also negatively affect the baby, because in the lower part of the uterus there is not such a good blood supply to the vessels as in its upper sections, and therefore it is possible that the fetus may lose oxygen and necessary nutrients.
However, it is not worthwhile to raise panic. In fact, the interruption due to low placentation results in less than 10% of all pregnancies with this pathology. Increasingly with increasing pregnancy, the placenta simply rises to the top and becomes in its place - and this can happen as in the middle of the term, and at the very end of pregnancy.
Symptoms of low placentaPregnancy with low placenta is characterized by low blood pressure (25% -34% of cases), late gestosis, lack of oxygen, tested by a baby. But in general, if the location of the placenta is not critically low, the woman does not observe any signs of this condition, and pathology is determined accidentally during the passage of the planned ultrasound.
If the placenta is located very low, the woman may display common symptoms of the threat of abortion: pulling the lower abdomen and lower back, bleeding from the vagina. It is worth keeping an eye on the signals of your body - detachment of the placenta is absolutely painless, so you need to observe mainly whether there are bloody discharge.
Low placentation: treatment
Pregnant should be very cautious: physical stress is undesirable, you can not overstrain yourself, you should give up sex. The fact is that under heavy loads, the pressure in the placenta can rise, which will cause severe bleeding. Therefore, in no case can you make sharp movements, even you must go to bed very carefully, do not go on transport, so as not to "shake" again. Even coughing is undesirable. When sitting, it is best to lift the legs slightly - this will improve blood circulation. If the doctor offers to lie down for preservation, then it is simply necessary. When bloody discharge from the vagina appears, go to the hospital immediately.
If the birth is close, and the placenta has not been put in place, then you should rely only on doctors. If the baby lies head to the yawn of the uterus, then there will be no cesarean. If there is a breech or foot presentation, then most likely - prokesareat. And, most likely - planned.
