Stasis dysmenorrhea is one of the symptoms of pelvic stasis syndrome. Pelvic stasis syndrome (also known as pelvic stasis) is a specific condition caused by chronic pelvic venous stasis and is one of the main causes of chronic pelvic pain in gynecology, mostly seen in menstruating women aged 30-50. The causes are mainly the following three: 1. Any factors that make the pelvic veins flow out of the pelvis poorly or obstructed can lead to pelvic venous stasis. 2. Compared with men, the gynecological pelvic circulation is very different in anatomy, circulatory dynamics and mechanics, which is the basis for easy formation of pelvic stasis. 3, As women do not pay attention to diet and rest during menstruation and often eat cool food, etc., they may cause stasis of blood. Patients with stasis dysmenorrhea should implement the policy of “prevention first” and take preventive measures to avoid or reduce the occurrence of pelvic stasis by addressing the causes of pelvic stasis. Pay attention to the combination of work and rest, avoid excessive fatigue, for long-term standing or sitting workers, when possible, should carry out interval exercises and appropriate activities. Pay attention to eating less greasy and indigestible food, less fried, smoked, barbecued, raw and cold, stimulating food and high salt and high fat food.
