The most common clinical cause of persistent menstrual failure during perimenopause is due to functional uterine bleeding during menopause. Functional uterine bleeding during perimenopause occurs because of the corresponding changes in hormone levels in the body during perimenopause. Ultrasound examination is recommended to rule out the possibility of organic lesions. If the endometrium is normal and there are no fibroids in the pelvis or uterus, symptomatic treatment can be given. Oral tranexamic acid or anorectic blood treatment can be given. Most of the patients will have clean menstruation after 3-5 days of hemostatic treatment. If it still stops, progesterone can be used to give treatment if organic lesions are excluded. Most of the vaginal bleeding will be cleared in 24-48 hours after medication, but it is important to note that bleeding may still occur after progesterone is discontinued, so take it as prescribed.
