Why can a pregnancy interrupted even at the earliest stages be a serious blow to a woman's health? The fact is that from the very beginning, pregnancy causes serious changes, restructuring in many organ systems of the female body, primarily in the central regulatory systems - nervous and endocrine (hormonal). A close functional relationship between the mother's organism and the embryo appears from the very moment of fertilization. Even before the introduction of a fertilized egg into the wall of the uterus, the development of the embryo is influenced by hormones: estrogens, progesterone, prostaglandins and other biologically active substances. They also prepare the inner layer of the uterus - the endometrium - for implantation of the embryo. Under the influence of hormones and biologically active substances, a gradual restructuring begins in the entire body of the expectant mother, especially pronounced in the so-called hormone-dependent organs: mammary glands, ovaries, uterus, external genitalia.
Any external intervention leading to an abortion is the cause of a sharp hormonal breakdown in a woman's body. This explains the insecurity of abortion, carried out even at the shortest time. A significant mismatch in the work of the central nervous and endocrine systems, caused by external interference, disrupts the normal functioning of the endocrine glands: the pituitary gland, thyroid gland, ovaries, adrenal glands - and contributes to the occurrence of nervous disorders of varying severity: exacerbation of autonomic dysfunction, mental disorders, sometimes with the development of depression, neuroses, etc.
