Yeah it is always a good idea with these things to see someone who specialises in it. I just know with my sister she had surgery twice so after that is when she started looking in to seeing the naturopath and started diet changes etc. The endo would prob have a lot to do with the bloating. It can also be common for women with endo to have IBS to so she may have a touch of that, which could be causing bloating and discomfort to and painful no# 2's, so that might be worth looking in to as well. I don't live in Melb so can't recommend anyone sorry!
