Characteristics of functional uterine bleeding in women at different stages

Dysfunctional uterine bleeding is caused by dysfunction of the nervous system and endocrine system, which is manifested by irregular menstrual cycle, prolonged bleeding time, heavy menstrual blood volume, and even heavy bleeding or continuous bleeding. It is divided into three types according to the onset period of women:

Dysfunctional uterine bleeding during puberty

Because the ovarian function and ovulation mechanism are not perfect during adolescence, due to high study pressure, mental stress or intense exercise, malnutrition, etc., ovarian dysfunction and abnormal sex hormone secretion may occur, resulting in irregular vaginal bleeding. At the time of menarche, the hypothalamus-pituitary-ovarian axis is in the process of gradual maturation, so within two years of menarche, irregular menstrual cycles are relatively normal and can generally be adjusted and restored by themselves. The basal body temperature curve is monophasic, which belongs to anovulatory functional uterine bleeding.

Dysfunctional uterine bleeding during pregnancy

Most of them are ovulatory, and most of them occur in the recovery period after childbirth or miscarriage. Generally speaking, the gonad axis of women of childbearing age should be in a stable state. Abnormal uterine bleeding is mostly organic lesions, such as inflammation, fat, uterine fibroids, endometriosis, etc., and should be checked and diagnosed in time at the hospital.

Dysfunctional uterine bleeding during menopause

Due to the gradual degeneration of ovarian function, menopausal women cannot produce mature follicles and ovulate, thus losing the normal cyclical changes of female hormones and causing irregular vaginal bleeding. Most cases are anovulatory functional uterine bleeding. Postmenopausal bleeding is the most common symptom. Vaginal bleeding occurs one year after menstruation stops. It is a symptom caused by non-organic, benign, or malignant lesions of the internal reproductive organs. Since menopausal women have more organic lesions, pathological examinations must be performed to find the cause.
