Non-menstrual exercise bleeding may be physiological or pathological. Physiological reasons are that there may be a small amount of bleeding during exercise before and after menstruation and during ovulation, while pathological reasons are mainly gynecological inflammation, cervical polyps, cervical erosion, submucosal fibroids and other diseases. Some women may have vaginal bleeding during ovulation due to estrogen deficiency, but this usually does not require special treatment and can be observed during follow-up visits. If there is vaginitis, cervicitis or cervical erosion, exercise may cause bleeding. Diseases such as cervical polyps and submucosal fibroids can also cause bleeding after non-menstrual exercise, which requires treatment of the original disease under medical supervision.
