What is a frozen pregnancy
By this name it is customary to understand a state when an embryo (or fetus) does not grow and does not develop and dies. Frozen pregnancy is also known as failed.
This can happen at different times, however, as a rule, it is observed at the beginning: 3-4 weeks and 7-11 weeks are considered critical.
Another dangerous period is from the 16th to the 18th week.
Women are very upset by this event. Naturally, they have questions: “Why did this happen to me?”, “Will this happen again?”, “Can I get pregnant again? To endure and have a baby safely? ”
Let’s try to figure it out.
What happens during a failed pregnancy?
Normally, the egg is fertilized by a sperm, enters the uterus, attaches to the wall of the uterus and begins to divide. A placenta is formed, an embryo is formed, and its internal organs are laid.
Sometimes the embryo stops growing, does not develop and dies in the uterus.
An embryo in an egg dies during a dead pregnancy
A frozen pregnancy, in contrast to a miscarriage, does not have obvious manifestations at first. It is determined by the results of a gynecological examination, ultrasound examination, and analyzes.
A special case of a missed pregnancy is anembrinia, when the fetal egg is empty – there is no embryo in it.
Causes of Frozen Pregnancy
Genetics is to blame
Breakdowns in chromosomes, genes are the most common cause, this happens early on. Violations are so serious that the embryo becomes unviable and dies.
Genetic abnormalities are either inherited or appear in this particular pregnancy due to exposure to a damaging factor, such as exposure to alcohol, a drug or radiation exposure.
These are all hormones.
When a child is born, hormonal changes occur: the body produces progesterone in large quantities. When progesterone is not produced enough or the body has a lot of androgens, pregnancy can stop.
All infections are dangerous for embryo development, but TORCH infections are especially terrible. It is they who are guilty in the late stages of deformities, and in the first weeks – of a frozen pregnancy.
Pregnancy may end due to infections
For some pathologies, antibodies are produced in the mother’s body that tend to destroy the cells of the embryo, recognizing them as foreign.
Blood clotting disorder
Due to the high viscosity of the blood, the embryo will experience oxygen starvation and eventually stop developing. A disease leading to such an effect is, for example, antiphospholipid syndrome. It is characterized including the formation of blood clots with blockage of blood vessels. If the vessels are clogged in the uterus, placenta, the embryo will receive less oxygen and nutrition.
Frozen Pregnancy: Risk Factors
mother’s age before 18 and after 35 years, father’s age after 35 years;
episodes of “fading” that occurred in previous pregnancies;
in vitro fertilization;
imbalance of sex hormones;
polycystic ovary syndrome;
inflammatory genital infections;
repeated abortions, intrauterine devices;
diabetes mellitus, hypothyroidism;
heart failure, arterial hypertension;
connective tissue diseases;
harmful addictions (alcohol, drugs, tobacco).
How to determine a frozen pregnancy
If this is the first trimester
The trouble is that during this period, pathology does not manifest itself in any way. Even test strips will show a positive result for some time. However, there are still indirect signs of a missed pregnancy.
1. At first, the state of health improves: nausea in the morning, vomiting ceases, and the heightened sensitivity to smell disappears.
2. They become soft, the mammary glands cease to be rude and hurt, their size decreases.
3. Another sign is that basal temperature decreases.
In the future, the embryo decomposes, the uterus rejects it. The following symptoms appear:
there are bloody veins in the discharge;
the state of health worsens due to intoxication – the stomach hurts, dizziness occurs, weakness is felt;
basal temperature rises sharply.
The doctor reveals a failed pregnancy. Carrying out an examination, he sees that the uterus does not fit the gestational age.
An ultrasound scan shows that the embryo has no heartbeat.
With a frozen pregnancy, all tests should be taken.
A study on hCG gives a decrease in its content in the blood.
When a miscarriage does not occur, the embryo must be removed, then curettage is performed. Otherwise, a strong inflammatory process that turns into sepsis is likely.
If this is the second trimester
How to understand that the pregnancy froze in the II trimester? Pathology is manifested primarily by the fact that the child no longer moves. When stirring is absent for more than two days, this is a serious reason for visiting a specialist.
