It is normal to have menstrual cramps without stomach pain. Dysmenorrhea is one of the common gynecological symptoms, which refers to pain and swelling in the lower abdomen before, during and after menstruation, accompanied by lumbar pain or other discomforts, and in severe cases, it may affect normal life and work. Some women experience dysmenorrhea during menstruation and some do not. Dysmenorrhea can be categorized into physiological dysmenorrhea and pathological dysmenorrhea. Physiological dysmenorrhea refers to the production of prostaglandins by the endometrium of the uterus during menstruation, and the high level of prostaglandins can cause excessive uterine contraction and vascular spasm, resulting in uterine ischemia and hypoxia, and dysmenorrhea occurs. Pathological dysmenorrhea is usually caused by women suffering from certain diseases such as endometriosis. Therefore, it is normal to have menstrual cramps without stomach pain, but if you have dysmenorrhea, you need to consult a doctor in time.
