Sudden bleeding after three years of menopause may be caused by acute vaginitis, cervical lesions, endometriosis and so on.
1. Acute vaginitis: Generally speaking, after menopause, due to the decrease of hormone level, the secretion will be reduced, and at the same time, the ability of the vagina to resist external bacterial invasion will also be reduced, so it is easy to be attacked by bacteria. If the inflammation is acute, it will be accompanied by burning sensation, vulvar itching, and occasionally there will be bloody discharge.
2. Cervical lesions: common as cervical polyps, cervical precancerous lesions, etc., can also lead to abnormal vaginal bleeding.
3. Endometriosis: this is the most common cause of postmenopausal bleeding, some of which are caused by uterine fibroids, endometriosis, etc., which will be accompanied by endometrial thickening.
Therefore, if bleeding occurs after menopause, then it is recommended to consult a doctor in time and choose the appropriate way to deal with it, so as to avoid delaying the condition.
