The cause of the disease is not known precisely and progress in recent years still do not allow elucidation of the origin of this disease. It is known however that hiperfoliculemia (overproduction of the hormones estrogen by the ovaries) and a poor function of the immune system influences it.
The theory of the reverse menstruation suggests that during menstruation some of the menstrual tissue goes back into the fallopian tubes and stops in the abdomen, where they increase. Some experts believe that this happens to all women and that an immune system problem or a hormonal one allow this tissue to grow and develop endometriosis. According to another theory, there is a hereditary predisposition to the appearance of endometriosis. In addition, a weak immune system may contribute to the development of endometriosis.

Another theory suggests that endometrial tissue is sent from the uterus in other parts of the body through the lymphatic system or blood veins. Another theory says that the disease is found in the genes of families or that some families have predisposition to endometriosis. Other researchers claim that the remains of tissue from the time when she was only one embryo can determine the development of endometriosis along the years or that some adult tissues retain the property they had in the embryo stage, that of transforming reproductive tissue in certain situations. Researchers found that exposure to dioxin causes endometriosis.
Also we must not forget the major role in developing these diseases and others that the accumulation of toxins in the body in all tissues and body fluids (under the theory of “broken blood” after which he guided Valeriu Popa in everything was good its peers).
