Aunt refers to menstruation. It is normal to have menstruation without stomach pain.
The formation of menstruation is related to the spasm and contraction of the endometrial spiral artery, resulting in ischemia, necrosis, and exfoliation of the distal blood vessel wall and tissues; when menstruation occurs, endometrial debris, cervical mucus, and shed vaginal epithelium are discharged from the body with the menstrual blood.
Some women do not have special symptoms during menstruation and do not have stomach pain, but sometimes, due to pelvic congestion and the effect of prostaglandins, they may experience a feeling of lower abdomen and lumbosacral region falling. In addition, some women may experience pain due to uterine contractions. Therefore, when menstruating, the presence or absence of lower abdominal pain can be normal.
If the pain is unbearable during menstruation, it is recommended to consult a doctor to find out if it is related to other diseases such as endometriosis and to follow the doctor’s instructions for targeted treatment.
