Menstrual disintegration generally refers to anovulatory dysfunctional uterine bleeding, and not all women who experience this symptom indicate that they are approaching menopause. Anovulatory dysfunctional uterine bleeding is a common gynecological disorder. Some women who have reached menopause will experience this type of menstrual abnormality due to changes in hormone levels in their bodies, and will usually experience menopause after a period of time. Adolescent women also experience anovulatory dysfunctional uterine bleeding. In addition to approaching menopause, many kinds of causes, such as endocrine disorders, overwork, excessive obesity, polycystic ovary syndrome and other factors may lead to the development of this disease. When a woman experiences symptoms similar to anovulatory dysfunctional uterine bleeding such as heavy menstrual periods and prolonged periods, she must seek medical attention in time and take reasonable measures under the guidance of a gynecologist.
