Uterine bleeding can occur at any age. Frequent causes are diseases of the uterus (tumors, inflammation, endometriosis), tumors and disorders of hormonal function of the ovaries. Uterine bleeding may be a manifestation of blood disorders with a violation of its coagulation system. Often, uterine bleeding complicates the course of pregnancy, childbirth and the postpartum period, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net Uterine bleeding in children under 12 years of age (before the onset of puberty). In newborn girls, during the first week (usually on the 5th-6th day) of life, bleeding from the genital tract may appear. This is due to the sloughing of the superficial layer of the mucous membrane of the uterus due to the termination of the action of the maternal sex hormones circulating in the fetus before birth. Bloody discharge from the genital tract ceases on its own 24-48 h.

In the following years, until the onset of puberty, M. are extremely rare and are a symptom of a special type of ovarian tumors that produce female sex hormones. In most cases these tumors are benign. Under the influence of female sex hormones produced by the ovarian tumor, the thickening of the mucous membrane of the uterus periodically occurs followed by its rejection, which is manifested by acyclic, ungentle menstrual-like secretions from the genital tract. Along with this, there are such signs of puberty that are not characteristic of the age of the girl, such as the enlargement of the mammary glands, the embryos of the external genital organs.

When bloody discharge from the genital tract occurs, a girl under 12 must immediately contact a pediatric gynecologist. If the diagnosis confirms the diagnosis of an ovarian tumor, the operation (removal of the ovary) is carried out without delay, since the tumor can be malignant. The examination reveals other causes of bloody discharge from the genital tract in children: foreign bodies and malignant tumors of the vagina.
