Endometriosis refers to endometrial tissue that grows outside of the uterus. It could occur around the ovaries or uterus, the bowel, or the lining of the pelvic cavity. Although no one has yet proven endometriosis' cause, there are three main theories.

1. Reverse menstruation

2. A weak immune system

3. Hereditary factors

Backward Menstruation

Also known as retrograde menstruation, backward menstruation can also be called this. This happens when the uterine lining is removed during the period. The menstrual fluid then flows backward through the fallopian. The fallopian tubes allow menstrual fluid, which is a liquid that drips into the pelvic cavity, to enter the pelvic. This allows the fluid to stick to any object it touches and start to grow. You can also browse this website to learn more about endometriosis causes.

Weakened Immune System

It has been reported that between 4-10% of women who have ever had endometriosis are menstruating. However, almost all women experience backward menstruation. Endometriosis can occur in all women. However, not all women will get it. The weakened immune system theory suggests that women with weaker immune systems are more likely to develop endometriosis. Women with stronger immune systems, however, can control or eliminate any endometrial tissue from the uterus.

The Hereditary Factor

Endometriosis is a condition that runs in families, suggesting a genetic connection. Some families might have a genetic risk factor that allows abnormal cells in the pelvic cavity to grow.
