In habitual miscarriage, treatment must start before conception. Before conception, the cause of the disease should be identified, and through treatment an intrauterine environment suitable for the survival of the fetus should be created. The earlier the patient receives treatment, the less the fetus will be affected by some adverse factors in the mother’s body. The treatment of habitual abortion varies according to the cause. The traditional classification of immune miscarriage can be divided into two categories, each with different treatment methods. If the HLA antigen compatibility between the couple is too large and the closed antibody is lacking, the treatment can be used to stimulate the production of closed antibody with lymphocytes from the husband or a third party, just like the body is vaccinated to produce antibody. Lymphocytes are administered every 2-4 weeks for 4 times as a course of treatment. Second, miscarriage caused by anatomical abnormalities of the uterus Most miscarriages caused by anatomical abnormalities of the uterus are late miscarriages, and treatment should be surgical correction, hysteroscopic surgery, or post-pregnancy cervical cerclage, depending on the specific cause. Miscarriage caused by other causes Miscarriage caused by endocrine disorders should be treated according to the specific causes. For example, patients with luteal insufficiency can be treated by progesterone supplementation, while diabetic women and patients with abnormal thyroid function should be stabilized before considering pregnancy. Do I have to be bedridden to keep the baby? The traditional concept of fetus preservation is to ask patients to nourish and minimize activities in order to achieve the goal of fetus preservation. In fact, this is a misconception. The so-called fetus preservation treatment should be aimed at various causes, according to the intrauterine unfavorable factors, and eliminate them one by one, so that the embryo can pass the ten months successfully. If the intrauterine unfavorable factors are not swept away, even if the patient is careful and bedridden during pregnancy, he or she will still miscarry. Only patients with active bleeding and some patients with habitual abortion due to anatomical factors need to be relatively bedridden; most patients do not need to be absolutely bedridden. To make a sapling grow strong, the first thing to do is to improve the soil in which it lives, and also to make the roots of the sapling as deep and firm as possible, so that it can absorb more nutrients and grow in the storm. Therefore, it is necessary to create an intrauterine environment suitable for the survival of the fetus, and early fetal preservation treatment can make the embryo absorb more nutrients to make the fetus stronger. The theory of fetal origin proves that a person’s physical condition in adulthood is closely related to the condition in the womb during the fetal period. Patients with habitual miscarriage should be treated from before conception and under the supervision of a doctor from the beginning of pregnancy to preserve the fetus. The medical staff of our department has returned from studies and training in Shanghai and Guangzhou and has achieved promising results in carrying out fetal preservation treatment, with a success rate of 85-90%.
