What causes uterine eversion?

Uterine eversion is also called uterine endometriosis, and there are many reasons that cause it. Some of them may be caused by menstrual blood and endometrial fragments falling off during menstruation reaching the abdomen, laying the foundation for the disease, or it may be caused by congenital factors. So what are the specific reasons? The editor has found four typical inducing factors. If you suffer from this type of disease, you can check to see which one it belongs to.

1. Implantation Theory

Menstrual blood flows backwards and endometrial implantation occurs. During the menstrual period, menstrual blood flows downstream from the cervix and vagina. However, a small amount of menstrual blood or other reasons mixed with shed endometrial fragments flow into the abdominal cavity through the fallopian ducts and implant on the surface of the pelvic organs to form endometriosis lesions.

2. Metaplastic endometrium

Serosa epithelium, metaplastic intima. During the human embryonic development period, the ovarian surface epithelium, peritoneum, vaginal rectal diaphragm, and umbilicus are all derived from the metaplasia of the body cavity epithelium. These tissues can be transformed under the stimulation of gonadal hormones, inflammation, and mechanical factors to form another type of tissue, which can also metaplasia into the endometrium.

3. Benign metastasis

Hematolymph, benign metastasis. This is a relatively rare cause of the disease. Endometriosis that occurs in the lungs, meninges, pericardium, limbs, and other distant parts is caused by the transfer of endometrial debris through the blood circulation or lymphatic system and retention in certain organs or tissues.

4. Iatrogenic endometrial transplantation

This is an artificial process that causes the endometrium to be transplanted to certain parts of the uterus. It is common in cesarean sections, curettage in early and mid-term pregnancy, episiotomy during delivery, and artificial abortion.

No matter what the cause of the disease is, timely treatment is the most important thing. Once the disease is caused by blood and lymph, it will not only harm the uterus, but also threaten the lungs and even the brain, so it should not be underestimated.
