Postmenopausal bleeding requires prompt medical attention to clarify the diagnosis, and the length of bleeding time cannot be used to judge whether it is normal or not. Benign postmenopausal vaginal bleeding is mostly caused by senile vaginal inflammation or cervical inflammation, and may be accompanied by itching symptoms, which can be clearly diagnosed through gynecological examination, vaginal secretion examination and cervical cytology under the guidance of a doctor, and can be restored to normal after active treatment. Repeated irregular vaginal bleeding may also occur after menopause, and it is necessary to be on high alert for gynecological malignant neoplastic diseases such as cervical cancer, endometrial cancer, etc. It is necessary to assist in diagnosis through cervical cytology, cervical biopsy, colposcopy, ultrasonography, and hysteroscopy under the guidance of a doctor, and when the diagnosis is made clear, it is necessary to comply with the instructions of the doctor to take active treatment. When postmenopausal bleeding occurs, it is necessary to go to the hospital in a timely manner to identify the cause and actively deal with it.
