Endometriosis is the growth of endometrial cells in places within your body in which they do not naturally grow.
Every month when it is time for you to have a period, your body sheds the inner lining of your uterus through your vagina. This is called menstruation. The cells that are inside the lining of your uterus are called endometrial cells. During menstruation when your uterine lining begins to break loose to be shed, a reaction occurs. Each of the endometrial cells releases microscopic amount of prostaglandin which causes the uterus to cramp and contract to expel the lining.
The uterus should contract from the top to the bottom in order to effectively expel the lining. In patients with endometriosis, the uterus contracts from the bottom up and can force endometrial cells up through the fallopian tubes and into the abdominal cavity. The endometrial cells then attach themselves inside the abdominal cavity where they continue to live.
Now, every month as you move through your cycle, these growths (in addition to the normal endometrial cells inside your uterus) swell up with prostaglandin which can cause nausea, vomiting, diarrhea, bloating, cramping (mild to severe), and flu like symptoms.
