The pain of girls’ abdominal cramps may be caused by dysmenorrhea, intestinal diseases, gynecological diseases and other reasons. 1. Dysmenorrhea: the pain mostly starts after the onset of menstruation, and the pain is the most intense on the first day of menstruation, and lasts for 2 to 3 days before it subsides. The pain is spasmodic and may be accompanied by nausea, vomiting, diarrhea, dizziness and weakness. 2. Intestinal diseases: such as acute enteritis, small bowel tumor, small bowel torsion, small bowel intussusception and other intestinal diseases, which may cause the intestinal tract to be stimulated by inflammation and compressed by the swelling, which may lead to spasmodic contraction of the intestinal wall, causing cramp-like pain in the abdomen. 3. Gynecological diseases: such as adnexitis, pelvic inflammatory disease and other gynecological diseases, in addition to causing hidden pain in the abdomen, cramp-like pain, but also lead to soreness or swelling in the lower back. At the same time, it will also be accompanied by symptoms of increased leukorrhea. When girls experience the symptoms of cramping pain in the abdomen, they should pay attention to cold and warmth, and avoid eating cold, spicy and stimulating foods. If the symptoms are serious and continue to be unrelieved, it is recommended to go to the hospital in time for abdominal ultrasound, uterine adnex ultrasound, blood routine, stool routine, leukorrhea routine and other tests, to clarify the cause of the disease, and actively carry out targeted treatment.
