What are the specific causes of endometriosis?

Endometriosis has many symptoms, the most typical of which is dysmenorrhea. So, what is the specific cause of endometriosis?

Endometriosis is a disease in which endometrial tissue grows outside the uterine cavity and has the ability to grow and function. If a woman with endometriosis becomes pregnant, the ectopic endometrium may undergo decidual changes.

The occurrence of endometriosis is related to the body's immune function, genetic factors, environmental factors, etc. The following is a detailed introduction to the specific causes of endometriosis:

1. Iatrogenic endometrial transplantation

This is an artificial process in which the endometrium is transplanted to certain parts of the uterus, and is more common in cesarean sections, early and mid-pregnancy curettage, episiotomy during delivery, and induced abortion.

2. Benign metastasis

Hemolymphatic, benign metastasis. This is a rare cause. Distal endometriosis such as the lungs, meninges, pericardium, limbs, etc. occurs when endometrial fragments are transferred to a certain organ or tissue through the blood circulation or lymphatic system.

3. Endocrine dysfunction

Regardless of the source, the growth and changes of ectopic endometrium are related to ovarian endocrine. Estrogen can promote growth, while progesterone can inhibit growth. Clinically, it is found that most patients lack progesterone, which promotes the occurrence and development of the disease.

4. Deficiency of immune defense function

The endometrium flows back into the abdominal cavity with menstrual blood, which is like a foreign body, activating the body's immune system and mobilizing a large number of immune cells and body fluids to eliminate it. If the body's immune function is defective, it will develop into endometriosis.
