Bleeding after sex may be a physiological condition, or it may be caused by pregnancy-related diseases, endocrine abnormalities, cervical lesions and other pathological conditions.
1. Physiological conditions: intercourse before menstruation may promote relatively early shedding of the uterine lining, resulting in a small amount of bleeding; if you have ovulation bleeding during intercourse, you may also have a small amount of vaginal bleeding; when the cervix has columnar epithelium displacement, intercourse may touch the columnar epithelium, resulting in a small amount of bleeding. Occasionally, the vaginal wall may be cracked due to sexual intercourse.
2. Pregnancy-related diseases: such as preeclampsia, ectopic pregnancy, trophoblastic diseases;
3. Endocrine abnormalities: such as abnormal ovarian function, hypothalamic pituitary abnormality, thyroid function abnormality, etc. All of the above conditions can lead to irregular vaginal bleeding;
4. Cervical lesions: such as cervical polyps, chronic cervicitis, pre-cancerous cervical lesions, cervical cancer, submucosal fibroids, endometrial polyps, adenomyosis, endometrial cancer, etc., which can lead to abnormal vaginal bleeding.
Vaginal bleeding during sex should be treated promptly to find the cause of the problem and to avoid any delay in the treatment.
