Many people ask me, “I’m pregnant for the first time and I’ve been very careful, how can I have a fetal abortion? What should I do? Actually, there is no need to be nervous and anxious if it is a single fetal abortion. Just like planting a crop cannot guarantee that every seed will germinate, we humans cannot be that good with every embryo. Studies have shown that more than half of the causes of abortions are due to problems with the embryo itself, such as chromosomal abnormalities. Such embryos should have been eliminated! The human body is amazing. In fact, the little baby in the womb is a homozygous graft for the mother because half of the baby’s genes come from the father! We humans reject any foreign tissue, but not the baby of “foreign origin”, which is a very complex mechanism. From the moment the embryo enters the uterus, it is constantly communicating with the uterus in a unique way. The mother’s uterus can sense whether the embryo is a good seed or not, and if she thinks it is not, she will try to reject it (and of course, she can make mistakes). This is the law of nature, the survival of the fittest. Of course, there are other factors that can cause fetal abortion, such as increasingly heavy environmental pollution (like the nuclear leak in Japan after the earthquake, I wonder how many fetal abortions there will be!) . In recent years, we have also felt that there seems to be more and more abortions and pregnancy has become difficult. Environmental pollution is something that we cannot resist. In addition to embryonic chromosomal abnormalities and environmental contamination (both of which we cannot solve), some patients do have organic diseases or immune problems. Therefore, patients with more than 2 fetal stoppages are usually subjected to systematic examination, including blood group, biochemical, endocrine and some immunological tests, and treated accordingly. However, medicine has limitations. So far, we have not been able to find the exact cause of many patients suffering from recurrent miscarriage, and only attempted treatment is available. Therefore, there is no need to be overly nervous when you unfortunately have a miscarriage, just relax and your next pregnancy will most likely go well. If you have more than 2 consecutive miscarriages, you should not take it lightly and should go to a regular hospital (preferably one with a reproductive specialty) for systematic treatment, rather than trusting in various prescriptions and drugs.
