What are the causes of habitual miscarriage?

Habitual miscarriage is a more serious form of miscarriage. After pregnancy, the embryo is difficult to stabilize and miscarriage will occur after a period of pregnancy. The embryo cannot thrive in the uterus. Habitual miscarriage casts a shadow on every happy family that wants to have a child. So, what is the cause of habitual miscarriage? Let's listen to the experts' introduction.

Reason 1: Hormone secretion imbalance

Normal ovulation depends on the normal secretion of various hormones, each of which plays an important role. 15% of patients with habitual miscarriage have symptoms of menstrual hormone imbalance, that is, one or more hormones are secreted too much or too little, the most common of which is progesterone and androgen problems. Take progesterone as an example. If the secretion of this hormone is insufficient, the fertilized egg will not be able to implant correctly in the uterus. Abnormal egg development may lead to insufficient progesterone secretion.

Reason 2: Uterine disease

Problems with the tissue inside the uterus can also cause miscarriage, and women often don't discover these problems until they become pregnant. Uterine fibroids are one culprit. Most fibroids grow on the outside of the uterus and don't pose a threat to pregnancy. But those that grow inside the uterus can take up space for the developing embryo and affect the blood supply to the embryo. Another uterine disease that can affect pregnancy is the septum, which prevents the egg from implanting properly and blocks blood flow to the placenta.

Reason 3: Chronic disease

Maintaining good health during pregnancy is essential, but it is difficult for women with chronic diseases to do so. 6% of recurrent miscarriages are caused by severe diabetes, thyroid disorders, or heart, kidney, liver diseases. But poor maternal health does not mean that you cannot raise a healthy baby. Pregnant women with chronic diseases can have a normal delivery under the guidance and monitoring of experienced obstetricians.

Reason 4: Poor immune system function

The pregnant woman's body is supposed to be an ideal incubator, a warm, nutritious place where safety is paramount. However, if the mother's immune system is compromised, the antibiotics that help the mother fight viruses will be passed on to the fetus and kill the growing creature. Experts disagree on the possibility that a poor immune system can cause miscarriage. Many doctors believe that less than 5% of recurrent miscarriages are caused by immune system problems.

Reason 5: Bad habits

It's very rare for a woman to have a miscarriage caused by environmental or lifestyle factors. Moderate exercise, sex, and computer work won't affect pregnancy. And that one glass of wine you had before you learned you were pregnant won't cause any trouble. But since there's no safe amount of alcohol to drink, it's safest not to drink.

Reason 6: Chromosome mutation

Fertilization is not a simple combination of sperm and egg. 23 pairs of chromosomes must combine successfully to form an embryo. In this complex combination process, a small mistake will lead to serious gene mutation. The direct result of gene mutation is that the embryo cannot survive. If the error in the combination process occurs early, you may not even realize that you are pregnant, and the fertilized egg will be expelled from the body, and the form is like a menstrual period; if it happens later, the result will be a dead fertilized egg or even a fetus without a heartbeat.

Warm reminder: Habitual miscarriage can cause great damage to women's bodies, and even more seriously, psychological damage. If habitual miscarriage occurs for a long time, infertility may also occur. Therefore, for habitual miscarriage, relevant prevention work needs to be done in daily life. Only by knowing the cause can targeted treatment be carried out.
