Athena has several good ideas. I was eating vegetable protein, not whey, smoothies made with fruit and veggies plus yogurt most of the time for 8-12 months before having my diversion to an ileostomy. When I did have meat it was chicken and didn't have beef for at least a year either.
My surgeon at Mayo's was a woman and she spent 3 hours lysing adhesions during the lapro surgery to divert me. I still had pain but could eat more solid foods again. She then spent 5 hours, out of an 8 hour surgery, lysing them during the j-pouch removal surgery.
The local surgeon that did my j-pouch and hernia surgeries told me that there was noting to do and I'd have to live with it. He had ordered a barium x-ray test done and there were no blockages. I looked at those x-rays. The barium made my intestines white on the film. Of course I wasn't having an obstruction problem when the test was performed. I felt he just ordered a test so he could dismiss my problem.
My GI at Mayo's was a man and I didn't feel dismissed, like I did with the local surgeon. I think it was the higher caliber of doctors at Mayo's not necessarily the sex of the doctor that was the difference.
