So, does Syndrome X have an "endo diet" in it, or can anyone recommend a website or book that would have this info?

My friend has just had a lap, inc a bowel section, where they removed 40cm. She's reconering but in a lot of pain. Shes been advised, I think, to have hormone medication (not sure what the right terms are here, and whether or not it would be HRT) but I think shed prefer diet if it would help.

thanks
