Endometriosis is defined as endometrial tissue growing in places outside the uterus. This could be around the ovaries, uterus, bowel or lining of the pelvic cavity. So far, no one has conclusively proven the cause of endometriosis, but there's three main theories.

1. Backward menstruation
2. Weakened immune system
3. Hereditary factors

Backward Menstruation

Backward menstruation is also known as a retrograde menstruation. This is where the lining of the uterus is shed during the period, then some of the menstrual fluid flows backwards into the fallopian tubes instead of normally exiting through the vagina. The fallopian tubes allow the menstrual fluid to drip into the pelvic cavity so that the menstrual fluid sticks to whatever it comes in contact with and starts to grow.

Weakened Immune System

While it's been noted that four to ten per cent of menstruating women develop endometriosis, it has been observed that backward menstruation occurs in almost all women. Since not all women get endometriosis, the weakened immune system theory states that because of the immune systems of some women, they may be more susceptible to endometriosis, while those with a stronger immune are able control or eliminate endometrial tissue growth outside the uterus.

The Hereditary Factor

It's been observed that endometriosis seems to run in families, thereby suggesting a genetic link. The theory goes that some families may have a hereditary risk factor that allows abnormal cells to grow in the pelvic cavity.

What to Do

Usually, endometriosis causes pain around the time of the period, but for some, unfortunately it can be a constant pain. If you have painful periods, pain in the pelvis, pain when ovulating, IBS, bladder pain or constant bladder infections, uncomfortable intercourse, or reduced fertility, see your doctor to determine if it is endometriosis. If the doctor determines that the cause of the pain is endometriosis, your doctor can then recommend a course of action.

Once you know for sure if it's endometriosis or not, you may also want to talk to someone at your local health food store and see if they have anything to boost your immune and ask about any supplements that can assist with proper female system functionality. There are lots of products on the market to assist with bodily functions, the key is to ask "who do you know that's getting good results and what is she using?"
