Causes of Dysfunctional Uterine Bleeding During Menopause

Dysfunctional uterine bleeding, referred to as "dysfunctional uterine bleeding", is a common gynecological disease. Women with menopausal functional uterine bleeding present with irregular uterine bleeding, irregular menstrual cycles, varying lengths of menstrual periods, varying amounts of bleeding, sometimes bleeding for several months, and anemia. The basal body temperature is monophasic, and the vaginal exfoliated cells are mainly bottom-layer cells, or middle and lower-layer cells. Cervical mucus crystals are poorly developed fern-shaped, and the endometrium is cystic hyperplasia or glandular hyperplasia. In blood endocrine examinations, the pituitary gland secretes elevated follicle-stimulating hormone, etc.

After women enter menopause, their ovarian function begins to decline, the hormone level of the ovaries decreases, and the feedback function to the hypothalamus and pituitary gland is lost, causing the gonadotropin secreted by the pituitary gland to increase to varying degrees. Although the remaining follicles in the ovaries also develop, they do not ovulate. Under the long-term effect of estrogen, the endometrial glands show a continuous hyperplasia reaction, which can cause mild hyperplasia, adenocystic hyperplasia, or adenomatous hyperplasia. When the estrogen level fluctuates greatly, the endometrium will shed incompletely, causing irregular uterine bleeding.

Traditional Chinese medicine believes that women's menstrual period is exhausted after 79 days, kidney qi is weak, and Chong and Ren meridians are weak, with kidney deficiency as the main cause. As menopausal women's kidney qi gradually declines, their organs lose function, and their spleen qi is weak, they often have no power to control and cause metrorrhagia. Therefore, menopausal functional uterine bleeding is more often manifested by the spleen failing to control blood type, such as sudden or continuous bleeding, pale color and thin blood, fatigue and shortness of breath, pale complexion, swollen eyelids, pale and fat tongue, and weak pulse. Treatment should be to invigorate qi and strengthen spleen, and consolidate Chong and Ren meridians.
