The moonbats adopted it, and Michael seized on it for his own alibi. But I gather it was invented by a lawyer for purposes of bringing the malpractice suit. (I think this is from Diana Lynne's book, but at the moment I don't have the book at hand to reference.) When Michael's legal team could not find any malpractice, one lawyer [who was mentioned by name] suggested suing for failure to treat [nonexistent] bulimia. The doctors' lawyers went along with it because it tended to implicate Terri in her own collapse and thus both exonerate the doctors and greatly reduce the settlement.
Later, the Medical Examiner, in his autopsy report, all but mocked the bulimia theory, albeit in polite medical language. He shot it full of holes. There you have retroactive proof, if any were needed, that the lawsuit was fraud.
But then, we didn't need an autopsy to make the point. We said it loud and clear in Free Republic long before Terri was put to death. The case that Terri's injury was not due to bulimia was overwhelming -- and it was proven correct.
The mystery remains: what caused her collapse? The one innocent explanation (bulimia) is gone. The one possible suspect has told several different stories about what happened that night. Either one of his stories is true and the rest are lies, or none is true and they all are lies.
So where's Columbo?
"In fact, when medical examiner Jon Thogmartin undertook the collection of Terri's medical records to launch his autopsy, he reported that he tracked her initial Humana Hospital-Northside admission records to Fox's office. According to Thogmartin, attorneys on both sides of the malpractice case conceded to the bulimia theory because there was nothing else 'to hang their hats on.'"
So: A consulting lawyer for Michael Schiavo had physical control of the medical records and made up the theory. Bad enough Fox was phishing the med records to contrive a malpractice case. But what was never revealed to the court or to the malpractice jury was the bone scan. I wonder if Fox had that document too? If he did, and suppressed it, the malpractice suit had to be premeditated flim-flam. Evidence that Terri was the victim of trauma would have gotten the suit thrown out of court on the spot.
I will hope and assume there is an innocent explanation for Mr. Fox's course of action; but it eludes me. For that matter, one looks in vain for evidence of integrity in any of Michael Schiavo's lawyers.
Actually the bulimia was invented by the ambulance chasing lawyers to blame the Doctor for malpractice for not seeing it and the fact that it would cause a potassium deficiency.
