Waiting for a baby is always a test of the female body for strength, especially when it comes to expectant mothers older than 30-35 years. But there are situations when the "interesting position" of the "age" Mom requires particularly careful control. What you need to know about late pregnancy after IVF and miscarriage, and also taking place against a background of various chronic diseases?
ECO: technology to help
Pregnancy, resulting from IVF, always requires increased attention. After all, unfortunately, it is not always possible to preserve it. According to various sources, about 30% of such pregnancies are interrupted before the 12-14 weeks period.
The main factors that lead to miscarriages of pregnancy after IVF:
- immunogenetic (eg, chromosomal changes in the cells of the parents);
- infectious (presence in the maternal body of a latent virus or bacterial infection - herpes simplex virus, cytomegalovirus, enterovirus, etc.
- endocrine. Stimulation of ovulation leads to hormonal changes. For hormonal support of pregnancy, which has occurred with the help of IVF, it is necessary to regularly determine in the blood the content of hormones responsible for its preservation - estradiol and progesterone.
- Early and frequent ultrasound to assess the dynamics of the fetus, ovary and uterus. Also, ultrasound examines the location of the embryo (low location can trigger miscarriage), the absence or presence in the uterine cavity of free fluid (eg, blood clots), detachment of the fetal egg, etc. All this allows to detect the threat of interruption in advance and take appropriate measures.
- Preimplantation diagnostics for the detection of chromosomal pathologies and certain genetic diseases, the passage of biochemical and ultrasound screenings to reduce the risk of congenital malformations of the fetus after IVF (they can be related to both the mother's ages and the causes of male infertility).
- Strict monitoring of the cervix (in the second trimester, itch-cervical insufficiency often develops and rapidly progresses, which in the worst case scenario can cause spontaneous miscarriage).
- Prevention of the development of viral or bacterial infection.
- The intake of vitamins-antihypoxants (C, E, beta-carotene, as well as folic acid) from the earliest pregnancy.
- probability of miscarriage;
- risk of intrauterine fetal pathologies;
- high infectious index.
Spontaneous abortion can provoke a variety of causes: genetic disorders and fluctuations in the hormonal background, pathologies of the cervix, external factors and stress. In addition, the female body at the age of thirty is often not able to take out the baby without the competent help of medical specialists. It may be due not so much to the fact that the older a woman, the more difficult it is for her to physically endure pregnancy, but also with the fact that with age in an egg, women undergo genetic changes, resulting in a fetus with genetic abnormalities that are often incompatible with life .
Most women successfully become pregnant again a year after the spontaneous abortion.
The risk of miscarriage depends both on the type of pathology leading to infertility and the age of the woman: up to 35 years - 10.5%, 35-39 years-16.1%, more than 40 years -42.9%.
What do you need to remember?
- Very often miscarriages occur due to chromosomal abnormalities of embryos, and with age they usually become frequent. During the period of pregnancy planning, it is advisable to undergo genetic counseling: a geneticist will examine your specific case and find out how likely the complications of the genetic plan are.
- Contact your doctor to have your new pregnancy under strict medical supervision, starting from the very shortest time.
- Adjust your diet for healthy food, drink plenty of water, do not forget about vitamins and rest more. Alcohol and smoking are banned!
- Keep a positive attitude. A long-awaited pregnancy can be difficult emotionally: memories of previous losses do not recede immediately.
Waiting for the baby is a serious pressure on the body, which can trigger a relapse of many "sleeping" before the disease. The greater the age of the future mother, the higher the likelihood that she has chronic sores. To diseases that complicate the course of pregnancy include:
- diseases of the cardiovascular system (hypertension, heart disease);
- diseases of the respiratory system (bronchitis, asthma);
- kidney disease (pyelonephritis, glomerulo-nephritis, urolithiasis);
