What is dangerous high hCh during pregnancy?

Pregnancy can be confirmed by a blood or urine test for human chorionic gonadotropin. This hormone is produced by a blastocyst (a fertilized egg in the next stage of division) after implantation in the uterus and in villi of the placenta. The task of the hormone is to maintain the production of progesterone of the ovarian yellow body, which is necessary for the development of the fetus. It should be borne in mind that increased hCG during pregnancy can indicate some abnormalities in the development of the fetus. In men, as well as in non-pregnant women, the presence of hCG in the blood can indicate testicular or ovarian cancer and other types of oncology.

As a rule, the level of gonadotropin in the blood is below 5 mU / ml, it is considered as negative, that is, the absence of pregnancy. The result above 25 MED / ml is considered positive and indicates that the woman is pregnant. Because embryo implantation can occur at different times after ovulation (an average of ten days), the growth of hCG during pregnancy begins several days after fertilization.

The embryo that moves through the uterine tube to the uterus consists of an embryonic node (a cluster of cells) and the surrounding layer known as the trophoblast. It is there that the production and secretion of gonadotropin begins, which reaches the ovaries, where it stimulates the newly formed yellow body to produce progesterone.

The chorionic hormone gonadotropin can be detected by blood and urine tests. A blood test can detect the presence of hCG and accurately determine the amount of hormones. This test can be used to determine if a woman is pregnant, whether the child develops normally or if the elevated hCG level is associated with cancer. The level of the chorionic hormone gonadotropin is often taken into account when screening birth defects. This test is usually conducted between the 15th and 20th week of pregnancy. In addition to blood, a urinalysis is also performed. This test does not provide an accurate measurement of hCG level, but shows the possible presence of a hormone. Urine for analysis should be collected immediately after awakening, because in the first portion the hgc level is the highest.

At the beginning of pregnancy, hGH is very low, and only with the passage of days its concentration will be doubled approximately every 48 hours and reach its maximum at 7-12 weeks, after which it will slowly decrease. Concentration xGh should grow twice every third week of pregnancy. When the value reaches 1200-6000 MDL / mL, growth will occur every 96 hours. Very high hCG in pregnant women can be associated with the pathology of the placental tissue, or indicate the occurrence of choriocarcinoma. In addition, increased hCG during pregnancy can be a consequence of multiple pregnancies. An abnormal increase in the level of gonadotropin can also occur in the case of an ectopic pregnancy, with birth defects in child development or miscarriage.

It is increased hCG in pregnancy is a symptom of molar pregnancy. As a result of a genetic error, after the fertilization of the egg, an abnormal growth of cells in the form of blisters in the placenta begins. And although a woman may have usual symptoms of pregnant women, such a chromosomal anomaly is extremely dangerous, since it can develop into a malignant form.

It should be remembered that increased hCG during pregnancy can cause nausea and vomiting. Unfortunately, such etiology is not fully understood. But most often an abnormal level of hCG occurs in women under 20 and after 35 years.

Of course, you should not compare the hCG level of different pregnant women on the same terms. His concentration may be quite different, vary throughout the period of bearing the baby and depend on the health and lifestyle of the woman herself. Most importantly, when hg is in the normal range and increases with weeks.
