Early menstruation is not necessarily a sign of aging. Early menstruation is generally a normal physiological phenomenon if it does not exceed 1 week. Because menstruation is affected by life habits, mental stress and other factors, it may occasionally occur early or late, usually within 7 days is normal. If menstruation is more than 1 week early, it may be caused by gynecological diseases or menstrual disorders. Some of the more common factors are uterine fibroids, endometritis, endocrine disorders, and so on. However, if older women continue to experience early menstruation, it may be due to ovarian failure. If early menstruation occurs frequently, it is recommended that the patient consult a doctor in time to identify the cause and treat the symptoms.
