Juvenile bleeding accounts for 1accounts for 10-20 % of all cases of dysfunctional uterine bleeding (2-3 % of school-age girls suffer from juvenile menstrual bleeding). The disease most often occurs in girls whose mothers had a pathological pregnancy, and the patients themselves suffered from acute and chronic infections.
As a rule, dysfunctional uterine bleeding during puberty is anovulatory in nature and occurs as follicular atresia. Depending on the duration of the follicle's existence, bleeding begins either at the expected period or after a delay in menstruation. Bleeding is usually profuse, not accompanied by pain, and quickly leads to anemia in the patient. Secondary disorders of the blood coagulation system often develop.
Dysfunctional uterine bleeding during the reproductive period can occur against the background of ovulation or be anovulatory, maintain cyclical bleeding or become acyclical.
In many cases (with follicle and/or corpus luteum insufficiency, with short-term rhythmic persistence of the follicle), women are not bothered by bleeding as such, patients are more concerned about the absence of pregnancy or its spontaneous termination. However, with follicle insufficiency, complaints of moderate or scanty blood discharge after menstruation, and a shortening of the menstrual cycle appear. Corpus luteum insufficiency may be accompanied by the appearance of spotting blood before the onset of menstruation. Such menstrual cycle disorders do not pose an immediate threat to health and life and do not require emergency care.
Significant or heavy bleeding accompanies menstrual cycle disorders that occur as a type of follicle or corpus luteum persistence, as well as as a type of follicular atresia. The onset of bleeding is preceded by amenorrhea of varying duration. Such bleeding is also typical for women in the premenopausal period. More than half of all cases of acyclic bleeding against the background of anovulation occur during this period of a woman's life.
