endometriosis is associated with a woman's monthly cycle. depending on where it is located determines the symptoms (it can be anywhere, but most common is the pelvic area). I had extreme constipation requiring laxatives on a regular basis, then diarrhea during cycle, extreme pelvic pain which pain killers did not stop, strong headaches, very heavy bleeding sometimes out of control. The all pain and bleeding got worse as i got older.
Then it seemed like food of anykind made me sick, even bland foods. often i could only stand a few bites before feeling nauseated. Mild exercise helped some (if i was not in too much pain). Salty foods seemed to help with the nausea. since endometriosis was also on bladder, it hurt just before having to pee, but emptying bladder helped. i had a large ovarian cyst made up of endometriosis. it was pressing on bladder and intestines, and was reason for all the symptoms. It is fed by estrogen, and i learned the hard way what foods made it worse. Do not eat flaxseed as they are very high in natural estrogen. My dr put me on a low fiber diet due to it being on my intestines, and to cook fruits and veggies as all plants have some estrogen in them and cooking helps kill it. also no food with added hormones.
