Almost menopausal birth control ring can cause bleeding, but vaginal bleeding also does not exclude endometrial hyperplasia, adenomyosis, endometrial cancer and so on. The birth control ring is a common intrauterine contraceptive device. If a menopausal woman has a dislodged or displaced birth control ring, bleeding will occur, and the patient should consult a doctor in time to have the birth control ring removed by a professional doctor. In addition to bleeding caused by the birth control ring, bleeding during menopause can also be caused by disease. Endometrial hyperplasia is most common in women around the age of 50, and may be caused by long-term estrogen stimulation without progesterone antagonism. Patients will experience abnormal bleeding, which may be accompanied by lower abdominal pain, uterine fluid and other symptoms. Adenomyosis is most common in women aged 30-50 years old, the etiology of which is still unclear. It may be caused by post-curettage, endometrial inflammation, etc. Patients will have prolonged menstrual period, mostly accompanied by abdominal pain and other symptoms. Endometrial cancer mainly occurs in postmenopausal and perimenopausal women, mainly manifested by abnormal bleeding, mostly accompanied by hidden pain in the lower abdomen, weight loss and other symptoms. If abnormal bleeding occurs when you are about to go through menopause, you should go to the hospital in time to avoid delaying your condition.
