Stomach pain during menstruation may be caused by elevated prostaglandin levels, uterine diseases, environmental factors and other reasons.
1. Elevated prostaglandin content: During menstruation, lysosomal enzymes dissolve the endometrial cells, thus increasing the prostaglandin content, resulting in excessive contraction of uterine smooth muscle and vascular contracture, causing the uterus to be in a state of ischemia and hypoxia, and the patient manifests the symptoms of abdominal pain.
2. Uterine diseases: such as endometriosis, adenomyosis, etc., due to the abnormal contraction of the endometrium and myometrial junction area, resulting in increased pressure in the uterine cavity, menstrual blood discharge is impeded and pain is triggered.
3. Environmental factors: prolonged extreme cold environment may cause vasoconstriction and stagnation of pelvic blood circulation, thus causing pain.
Menstrual stomach pain can also be caused by other reasons, it is recommended that the patient timely consultation, under the guidance of the doctor for treatment, to avoid delay in the condition.
