Women are generally called menopausal after the age of 50, when they have been amenorrheic for more than one year continuously. Normally, normal menopausal women do not have vaginal bleeding again. Vaginal bleeding again after menopause is called postmenopausal bleeding. Postmenopausal bleeding is not a disease, but a clinical condition. Postmenopausal bleeding is likely to indicate some kind of pathology and often attracts the attention of many women. Most of them can go to the hospital promptly after bleeding, but there are many women who, due to lack of awareness, start to become worried once they have postmenopausal vaginal bleeding, worrying if they are suffering from some kind of cancer. Later on, after her daughter’s persuasion, Auntie Liu visited the hospital and was examined and found to have age-related vaginitis. So, what are the causes of postmenopausal vaginal bleeding? What gynecological diseases should I be aware of? Postmenopausal bleeding is usually caused by the following reasons 1.Malignant tumors of reproductive organs, the most common one is endometrial cancer, which accounts for about 80% of malignant lesions, others are cervical cancer, ovarian cancer, fallopian tube cancer, vulvar and vaginal tumors, etc. 2.Benign lesions of reproductive organs, such as uterine fibroids, endometrial polyps, cervical polyps, etc., and some inflammatory lesions such as endometritis, senile vaginitis, etc. 3. Postmenopausal bleeding caused by endogenous or exogenous estrogen. Vaginal bleeding can be caused when estrogen fluctuates. Similarly, bleeding can also occur when the endometrium receives the action of foreign estrogen. For example, if older women take medications or supplements, they may bleed after taking estrogen or progestin drugs or supplements containing these hormones. About the causes of postmenopausal vaginal bleeding in women. A retrospective study on 446 patients with postmenopausal vaginal bleeding showed that. Inflammation caused postmenopausal vaginal bleeding in 241 cases, accounting for 54.0%, and malignant tumor caused bleeding in 56 cases, accounting for 12.6%, of which endometrial cancer had the highest incidence. Therefore, most postmenopausal bleeding is caused by benign gynecological diseases, and inflammatory diseases are the most common among benign diseases. However, the longer the time of menopause, the higher the incidence of malignant tumors. For patients with postmenopausal vaginal bleeding, detailed medical history, gynecological examination, cervical cytology and histological examination should be performed to clarify the cause, exclude organic lesions and provide early treatment. Medically, it is not difficult to diagnose postmenopausal bleeding, and with individualized treatment, good results will be achieved. In short, for postmenopausal bleeding to be alert, but never fear, once the postmenopausal bleeding, worry, fear is useless, to timely hospital consultation, obstetrician and gynecologist will help patients to clarify the cause as soon as possible, to achieve early detection, early treatment. Just like Aunt Liu, never delay the best time to treat the disease, to be able to live happily with their own bodies.
