The point is, the doctors couldn't conclusively determine bulimia either. You'd think there would be evidence in her mouth, gums, teeth, esophagus etc, of habitual vomiting, but nothing.
One of Terri's close friends testified that she had lunch with her shortly before her collapse, and Terri only ate a bagel, and she was concerned that Terri ate so little.
My point is that as far as I know eating very little is NOT characteristic of people with bulemia, just the opposite -- they gorge themselves and purge.
Years before Terri met Michael, she lost a lot of weight using Nutrisystem -- a healthy way of losing weight.
Put all this together, and I find it extremely unlikely, that Terri had bulemia.
But no mention is made and no attention is paid to the above facts.
