Bowel disorders do not usually interfere with normal menstrual flow. Normal menstruation depends on the normal secretory function of the hypothalamic-pituitary-ovarian axis, and intestinal disorders do not usually affect the normal secretory function of this axis. Menstrual flow is closely related to many factors, such as the hypothalamus, pituitary, ovaries, uterus, external environment, and psychological state. If the intestinal disease seriously affects the patient’s mental health, making the patient overly stressed or stressed, then endocrine disorders may also occur and lead to menstrual irregularities. Therefore, when menstrual disorders occur, it is important to go to the hospital for relevant examinations to exclude organic lesions and endocrine disorders before considering the influence of other factors.
