Constipation is a very common gastrointestinal dysmotility disorder that is caused by a variety of factors and is related to menstrual irregularities. Patients with irregular menstruation are usually prone to hormonal abnormalities and mental stress. Hormonal abnormalities when the ratio of estrogen and progesterone is out of balance lead to pelvic congestion, which can cause constipation by compressing the intestines. Constipation can also be apparent if you are more nervous before or after your period. In view of the above, it is recommended to consume more coarse cellulose food, try to avoid excessive emotional excitement and tension, and avoid intake of spicy and stimulating food. In addition, you can take Chinese herbal medicine to regulate menstrual disorders, and constipation can be improved.
